If you’ve ever been in a supplement store, you know just how many protein powder varieties there are. Even if you know your fitness goals—losing weight, building muscle, or maintaining your daily protein intake—it is overwhelming to choose the best protein powder out of all of them.
Our team of certified nutrition coaches, personal trainers, weightlifting coaches, and elite athletes has collective decades of experience in the fitness industry. Each of us consumes protein powder regularly, including the best whey proteins, casein proteins, collagen proteins, and plant-based proteins; in fact, we’ve tried over 150 protein powders over the years.
For this best-of list, we consulted with Laila Ouldibbat, RD, a New York City-based registered dietitian who’s pursuing a Ph.D. in Biological Sciences, and Perry Nix, MS, RD, LD, to give you our top picks for the best protein powder. We followed our in-depth protein powder testing methodology to evaluate each product on the following factors, giving them a score of 1 to 5 for each category:
- Formulation: Protein powders were given a 4 out of 5 if they contained at least 20 grams of protein, with considerations for added ingredients. We also looked for any use of artificial ingredients, which some users may wish to avoid. Perfect 5-out-of-5 scores were given to products high in protein that didn’t use any artificial ingredients or fillers.
- Taste: An average protein powder tasted fine to our testers; not the best, but not the worst—our standard for a 3-out-of-5 rating. The highest taste scores were awarded to the flavors we loved and looked forward to having again.
- Transparency and third-party testing: Has it been tested for potential contaminants and banned substances? Are there any certifications of analysis (COAs)? For a 3 out of 5, the manufacturer seems fairly transparent, but the product is not certified by a major organization like NSF, Informed Choice/Sport, or Banned Substance Control Group (BSCG).
- Price per serving: The average protein powder we’ve tested costs around $1.85 per serving. We give 3 out of 5 stars to proteins that cost between $1.50 and $1.90 per serving.
We worked with an independent, accredited lab—Ellipse Analytics—to test and rate more than 150 protein powders for purity and label accuracy. The lab analyzed each protein powder for the presence of heavy metals, harmful chemicals, and pesticides, since frequent or significant exposure to these substances can negatively impact your health. The protein powders below ranked in the top 50% of the samples tested. Finally, we asked Dr. Jennie Stanford, MD, with a degree in nutrition and dietetics, to medically review this content for accuracy and updated studies.
The GGR team helped over 13,500 people find their ideal protein powder in 2024; now let’s find yours.

Best Overall Protein Powder: Transparent Labs 100% Grass-Fed Whey Protein Isolate
Updated by: Matt Dustin, CSCS, PN1-NC
Our testers love Transparent Labs 100% Grass-Fed Whey Protein Isolate because we know exactly what’s in it, and almost every flavor we’ve tried is a 5 out of 5 on taste. Yes, it’s a little more expensive than other protein powders but you get what you pay for.
At a Glance
- Above-average protein content
- Excellent formulation
- Strong third-party testing
- Expensive, but high-quality
Transparent Labs 100% Grass-Fed Whey Isolate has an excellent formulation, earning 5 out of 5 stars for this category. Laila Ouldibbat, R.D., likes the short ingredient list—there are only five—and the fact that it’s free of artificial dyes, preservatives, and fillers. Most importantly, it’s essentially pure protein, with 28 grams coming from the macronutrient responsible for building muscle and increasing satiety (the feeling of being full), while containing minimal amounts of fats and carbohydrates.1
Formulation: 5/5
Taste: 5/5
Solubility: 5/5
Why We Like Transparent Labs 100% Grass-Fed Whey Protein Isolate
Transparent Labs’ whey isolate has one of the highest protein contents we’ve seen with 28 grams per scoop. It also has a short, simple ingredient list and is very low in carbs and fat.
Anthony O’Reilly, CPT, CNC, tried the seasonal Peppermint Hot Chocolate flavor and gave it 5 out of 5 stars for the taste. He said, “Peppermint Hot Chocolate: It’s exactly that—all you need is some whipped cream and marshmallows to complete the scene.”
If you’re an athlete, you’ll also be happy to hear that Transparent Labs products have been checked by Informed Sport for any banned substances. GGR also enlisted Ellipse Analytics—an independent, accredited lab—to test Transparent Labs’ whey isolate. It ranked as an “Above Average” product overall, meaning it passed our rigorous quality screen for both protein content and purity.
Anthony also noted that he didn’t experience any digestive stress from using this product, which may happen when regularly using whey proteins.
“I’ve been taking Transparent Labs protein for about a month, and overall I have to say I’m a big fan,” Anthony explains. “I haven’t experienced any stomach or digestive issues after drinking it, as I sometimes do with other whey protein powders—several customer reviewers said the same thing.”
The powder easily mixes into the liquid of your choice and leaves behind no clumps—this is one of the smoothest protein powders I’ve ever had.
Anthony O’Reilly, CPT, CNC
Alternatives
If there’s one callout we have with Transparent Labs whey protein isolate, it’s the price. At $1.99 per serving, it’s not cheap, and it only earns 3.5 out of 5 stars for its value. However, Transparent Labs recently began offering Whey Isolate in 4-pound tubs, which brings the cost per serving down to roughly $1.82. Also, they are known to offer occasional sitewide sales, so you can stock up at a discount.
Also, you get what you pay for, and Transparent Labs provides high-quality ingredients with clear labeling and third-party testing. Just know that it’ll cost more than similar products on the market.
If you’re interested in trying a whey protein isolate but prefer something more affordable, we recommend trying Dymatize ISO 100. Depending on the size of the tub you order, ISO 100 can cost as little as $1.00 per serving.
Testing Breakdown
Here’s how Transparent Labs 100% Grass-Fed Whey Protein Isolate scored for each of our testing categories.
Vs. The Average
Transparent Labs whey isolate is above average in nearly every category. Here’s how it compares to the average protein powder.
| Transparent Labs 100% Grass-Fed Whey Protein Isolate | Average Protein Powder | |

Best Clean Protein Powder: Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate
Updated by: Matt Dustin, CSCS, PN1-NC
Legion Whey+ is a clean, sustainable protein powder that also is macro-friendly and a great option for anyone looking for a clean protein supplement. Many of our testers have bought this with their own money because they love the taste and easy mixability.
What our tester says:
“It tastes like the milk at the bottom of a bowl of Cinnamon Toast Crunch.”
At a Glance
- Grass-fed whey protein isolate
- No artificial sweeteners
- Research-backed formulation
- Plenty of tasty flavors
Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate is a third-party tested whey protein powder that’s become a favorite of ours, and we appreciate that each serving has a balanced macronutrient profile that contains no artificial sweeteners or fillers. This clean protein powder earns 5 out of 5 for the formulation due to its all-natural, high-quality ingredients.
The GGR team has tried several flavors of Legion Whey+ and found most, if not all, to be very tasty and enjoyable.
Formulation: 5/5
Taste: 4.5/5
Solubility: 5/5
Why We Like Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate
Legion Whey+ contains no artificial ingredients and is tested by Labdoor, a third-party laboratory that ensures supplements are free from heavy metals and banned substances. In other words, athletes and those looking to prioritize all-natural supplements can take this clean protein powder with peace of mind knowing it’s antibiotic-free, hormone-free, GMO-free, and sugar-free.
We also love the flavors. Anthony O’Reilly, a certified nutrition coach and certified personal trainer, awarded the Cinnamon Cereal flavor a 5 out of 5 on taste and says, “It tastes exactly like the milk at the bottom of a bowl of Cinnamon Toast Crunch. It’s delicious.”
I’ve purchased multiple Legion flavors, myself, and find them all to be very tasty without any unpleasant or overpowering taste from artificial sweeteners.
The Vanilla option is perfect for my morning fruit smoothie because it adds a hint of flavor, and gets me more than 20 grams of protein.
Kate Meier, NASM-CPT, USAW-L1, CF-L1
Alternatives
Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate uses clean ingredients with no artificial additives, and the company is very transparent about its formulations, with research-backed doses and third-party testing.
However, one callout is that protein content ranges from 22 to 24 grams, depending on the flavor, which is slightly lower than average. For the relatively high cost, we’d like to see a slightly higher protein content, though this won’t be a dealbreaker for everyone.
Anthony also pointed out that some of the ingredients may cause digestive issues, noting, “Some flavors contain sunflower creamer, xanthan gum, and sunflower lecithin, and though these natural ingredients aren’t harmful from a nutrition standpoint, they may cause digestive problems in some people.”
If you want something that’s a bit higher in protein but still earns 5 out of 5 stars for the formulation, we recommend Transparent Labs 100% Grass-Fed Whey Protein Isolate. It still contains sunflower lecithin, but skips the xanthan gum and sunflower creamer.
Testing Breakdown
Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate scored exceptionally well for its formulation, solubility, and potential side effects. You’ll find more of our ratings in the following chart.
Vs. The Average
Here’s how Legion Whey+ stacks up against the competition. It’s a little bit lower in protein, but wins in most other categories.
| Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate | Average Protein Powder | |

Best Plant-Based Protein Powder: Swolverine Plant Protein
Updated by: Matt Dustin, CSCS, PN1-NC
Swolverine Plant Protein is a high-protein, plant-based blend that includes both pea protein isolate and pumpkin protein, offering a complete amino acid profile. It tastes great, but our testers reported that solubility can be a slight issue.
At a Glance
- Plant-based protein blend with pea protein isolate and pumpkin protein
- Non-GMO, dairy-free formula
- Contains added dietary fats
- No artificial sweeteners
Swolverine Plant Protein is a high-quality formula that’s made of pea protein isolate and pumpkin protein, providing a complete amino acid profile that helps it earn 5 out of 5 stars for the formulation. This isn’t always the case with plant proteins, which is one of the reasons we love this dairy-free, lactose-free formula and think it’s one of the best vegan protein powders.
It also includes added healthy fats from virgin olive oil, medium-chain triglycerides (MCTs), and coconut oil to provide a smooth taste and increased satiety, or how full you feel after drinking it.
Formulation: 5/5
Taste: 5/5
Solubility: 4/5
Why We Like Swolverine Plant Protein
Many plant-based protein powders are either low in protein, high in calories, or don’t contain the full spectrum of essential amino acids. Swolverine addresses all of these, delivering a high-quality formula that contains all the amino acids you need to recover from a tough workout.
It’s available in three flavors, and our tester was pleasantly surprised by the taste, which she says is delicious, without being overwhelmingly sweet. She notes, “The cinnamon flavor with a hint of salted caramel was delish, and I recommend this to someone who wants a sweet-tasting protein powder that isn’t actually stomach-sickening sweet.”
Swolverine is also third-party tested, GMO-free, and free of all artificial sweeteners and additives.
This is a good plant protein. It’s sweetened with stevia and uses primarily pea protein isolate—both good.
Bob Iafelice, MS, RDN, LDN
Alternatives
We think this is one of the better plant-based options on the market due to its formulation, taste, and high-quality ingredients. It’s hard to find a plant-based protein that can outshine Swolverine when it comes to these three main categories.
However, one callout we have is the solubility. It earned 4 out of 5 stars, which is impressive for a plant-based protein, but still may bother some.
“It was pretty foamy when I first shook it,” says our tester. “There were no visible clumps or chunks in the bottom, but there was slight separation once it settled, so more shaking could be useful. It’s definitely a bit gritty in the water mixture. Adding more water and mixing it more helped get rid of this chalky texture, and it overall is way better than most plant-based protein powders.”
We also wish the label was a bit more transparent, “The main drawback is the absence of an amino acid profile showing the amount of BCAAs, particularly leucine,” explains Bob Iafelice, RD and one of our expert contributors. “Other good plant proteins list BCAAs—this is an important piece of information to know.”
If you want a plant-based formula with better solubility, we recommend Ora Organic Daily Superfood Plant Protein. It earned 5 out of 5 stars for solubility, with our tester noting that it mixes surprisingly well with no clumping.
Testing Breakdown
Here’s how Swolverine scored, using our protein testing methodology.
Vs. The Average
Here’s how Swolverine Plant Protein compares to the average protein powder. While it’s more expensive than most dairy-based protein powders, it’s very competitive when it comes to both calories and protein per serving, which isn’t the case with most plant-based powders.
| Swolverine Plant Protein | Average Protein Powder | |
| Price per serving | $2.06 | $1.85 |
| Calories per serving | 140 | 130 |
| Protein per serving | 25 g | 25 g |
| Available flavors | 3 | 8 |
| Third-party tested? | Yes | Yes |
Best Chocolate Whey Protein Powder: Kaged Whey Protein Isolate
Updated by: Matt Dustin, CSCS, PN1-NC
Kaged Whey Protein Isolate is a fast-digesting protein powder with 25 grams of protein and just one gram of sugar per serving. Available in three flavors, we highly recommend Kaged if you’re a choco-holic.
At a Glance
- Low-calorie whey protein isolate
- Added digestive enzymes
- Contains artificial sweeteners
- May be a little clumpy in a shaker cup
After trying Kaged whey isolate in chocolate, our tester, Nicole Davis, CPT, PN1-NC, gave it 4.5 out of 5 stars for the taste. “I tried Chocolate and it’s one of the best chocolate proteins I’ve tried,” she told me. “In fact, I reordered, which is rare. It’s a strong chocolate flavor without tasting artificial.”
Unlike other powders that contain solely whey protein isolate, Kaged features ProHydrolase for enhanced protein absorption and muscle recovery. It’s also a clean product with minimal ingredients, though it does contain sucralose, which some may prefer to avoid. It’s available in limited flavors, but the Chocolate flavor is the best-tasting chocolate protein powder we’ve tested.
Formulation: 4/5
Taste: 5/5
Solubility: 3.5/5
Why We Like Kaged Whey Protein Isolate
Kaged products are Informed Sport certified, so athletes can use them with peace of mind that they’ve been checked for banned substances. GGR also tested Kaged’s whey isolate using Ellipse Analytics, an independent, accredited lab, for label accuracy (protein content), as well as purity (heavy metals, bisphenols, phthalates, and pesticides). It scored as “Meets Standard” overall, which means that it passed our rigorous quality screen.
In addition to having strong third-party testing, Kaged also does an excellent job with its flavors. Nicole likened the Chocolate flavor to “one of those Carnation instant breakfast mixes.”
It’s mostly natural with minimal ingredients, but they fumbled at the 5-yard line by including sucralose as a sweetener along with the stevia. That said, the macros are great for those on a cut.
Destini Moody, RD, CSSD, LD
Alternatives
Kaged is one of the best-tasting chocolate proteins we’ve ever tried, but as Nicole pointed out, solubility may be an issue, despite this being a whey protein isolate. Kaged only earns 3.5 out of 5 stars for solubility.
“It’s a bit chunky when mixed with cold milk or water in a shaker bottle, even using a shaker ball,” says Nicole. “I’ve also blended it in a shake with ice, and that ends up fine. I had the same experience with both chocolate and vanilla.”
If you want a high-quality whey protein isolate that has excellent solubility with no floaters or clumps, we recommend Transparent Labs 100% Grass-Fed Whey Protein Isolate.
Testing Breakdown
Here are the individual category scores for Kaged Whey Protein Isolate.
Vs. The Average
Kaged matches the average protein in nearly every category, with the exception of available flavors. Here’s a comparison that breaks down the details.
Kaged Whey Protein Isolate | Average Protein Powder | |
| Price per serving | $1.70-$2.20 | $1.85 |
| Calories per serving | 100-120, depending on the flavor | 130 |
| Protein per serving | 25 g | 25 g |
| Available flavors | 3 | 8 |
| Third-party tested? | Yes | Yes |

Best Whey Protein Powder: Momentous Grass-Fed Whey Protein
Updated by: Matt Dustin, CSCS, PN1-NC
If you are willing to pay a premium price for a high-quality grass-fed whey protein, the Momentous brand is a solid choice. It is cold-pressed and put through a micro-processing filtration that’s supposed to preserve the protein’s amino acid profile. While we cannot confirm that, we know it tastes darn good and did not upset any stomachs during testing.
At a Glance
- Smooth, delicious consistency
- Grass-fed whey isolate
- Contains added digestive enzymes
- Only available in four flavors, including unflavored
Momentous Grass-Fed Whey Protein utilizes grass-fed dairy, which has higher concentrations of antioxidants and omega-3 fatty acids compared to grain-fed dairy.7 The dairy is sourced from European cows that have not been administered antibiotics or growth hormones. As such, it earns a stellar 5 out of 5 for its formulation and the title of best whey protein powder available today.
It’s expensive, but worth it for those who want the best.
Formulation: 5/5
Taste: 4.5/5
Solubility: 5/5
Why We Like Momentous Grass-Fed Whey
The first thing we love is the formulation. Momentous uses a grass-fed whey protein isolate, which is easier to digest than a whey concentrate since a lot of the fat and lactose has been removed.
It’s also delicious, and both of our testers were very impressed with the flavor. Momentous earned 4.5 out of 5 stars for its taste, according to our expert product tester.
“We tried chocolate; It has a rich taste, it tastes very much like cocoa; it tastes a lot like hot chocolate (only we mixed it with ice cold water),” our tester explains. “I would buy this and I’d drink this again based on taste. Goes down really smoothly, really easily.”
Unlike other powders that solely contain whey protein isolate, Momentous also has ProHydrolase2 for improved protein absorption and muscle recovery.
It was ok with water, but very good with milk. With milk, the flavor reminded me of vanilla bean ice cream.
Anthony O’Reilly, CPT, CNC
Alternatives
We’re huge fans of Momentous Grass-Fed Whey. From the clean formulation to the excellent taste and solubility, this is one of the best whey protein isolates we’ve tested. It’s naturally sweetened with stevia, but still earns 4.5 out of 5 stars for the flavor.
However, just like a good steak, you get what you pay for, and Momentous isn’t cheap. We think it’s worth the price for those who want the best of the best, but it’s certainly on the pricier end of the protein spectrum. It costs $2.39 per serving, while the average protein only costs $1.80 per serving. As such, Momentous only earns 1 out of 5 stars for the price per serving.
For a more affordable, yet still high-quality whey protein isolate, you may want to try Dymatize ISO 100 instead.
Testing Breakdown
Here’s a complete breakdown of how Momentous Grass-Fed Whey scored according to our testing methodology.
Vs. The Average
Momentous is expensive, but it excels in nearly every other category. Here’s a look at Momentous Grass-Fed Whey Protein versus an average protein powder.
| Momentous Grass-Fed Whey Protein+ | Average Protein Powder | |
| Price per serving | $2.39 | $1.85 |
| Calories per serving | 90-100, depending on the flavor | 130 |
| Protein per serving | 23.3 g | 25 g |

Best Budget Protein Powder: Dymatize ISO 100
Updated by: Matt Dustin, CSCS, PN1-NC
Available in 13 different flavors that will satisfy a wide range of taste buds, Dymatize ISO 100 is stacked with 25 grams of protein, including 5.5 grams of BCAAs and 4.4 grams of glutamine designed to enhance muscular growth and recovery. However, keep in mind that it’s sweetened with sucralose, and some flavors contain artificial ingredients.
At a Glance
- Delicious flavors
- Easy to mix
- Hydrolyzed whey isolate
- Third-party tested
At around a dollar per serving—depending on the size and flavor you choose—Dymatize ISO 100 is one of the most affordable protein powders available and gets a 5 out of 5 on our pricing scale.
Dymatize ISO 100 utilizes 100% hydrolyzed whey protein isolate, which helps maintain a high protein content per serving while keeping the fat and carbohydrate contents low. It mixes well, and there are plenty of interesting flavor options.
Formulation: 4/5
Taste: 3.5/5
Solubility: 4.5/5
Why We Like Dymatize ISO 100
With 25 grams of hydrolyzed whey protein isolate and just a gram or two each of fat and carbohydrates (depending on the flavor), Dymatize ISO 100 gets a 4 out of 5 for its formulation.
We deducted a point, though, because there may be some ingredients that people want to avoid, like sucralose and food coloring.
It’s available in a variety of flavors, too, including some notable collaborations with brands like Dunkin’ and Post Fruity Pebbles. The flavors are pretty sweet, but this can be adjusted by using more liquid to mix your shake.
It was a little thin with water; I like it, but it’s nothing different from other chocolate protein powders. With milk, though, it tasted and felt more rich.
Amanda Capritto, CPT, CNC
Alternatives
Dymatize ISO 100 is an excellent choice for those looking for an affordable, third-party tested whey isolate protein powder. However, some of the flavors are a bit sweet, and we know that some may wish to avoid artificial sweeteners. “For me, I need to be careful about which flavor I choose,” notes Ben Emminger, NASM-CNC, NASM-CSNC. “Some tastes are practically tooth-rotting and not something I especially look forward to post-workout.”
Overall, this earns 3.5 out of 5 for the flavor, so it’s slightly better than average, but we’ve had better.
If you’re looking for an alternative that’s free of artificial ingredients and received a 5-out-of-5-star rating for its flavor, we recommend Transparent Labs 100% Grass-Fed Whey Protein Isolate instead.
Testing Breakdown
Multiple team members tested Dymatize ISO 100, and here’s how it scored.
Vs. The Average
Despite the flavor being a bit sweet for our taste, Dymatize ISO 100 still outshines the average protein powder in nearly every category, as you can see in the table below.
| Dymatize ISO 100 | Average Protein Powder | |
| Price per serving | As low as $1.00 per serving | $1.85 |
| Calories per serving | 110-120, depending on the flavor | 130 |
| Protein per serving | 25 g | 25 g |
| Available flavors | 14 | 8 |
| Third-party tested? | Yes | Yes |

Best Organic Protein Powder: Ora Organic Daily Superfood Plant Protein
Updated by: Matt Dustin, CSCS, PN1-NC
Ora Superfood Plant Protein combines a vegan protein and greens blend. Each serving has at least 21 grams of protein, 3 servings of greens, and digestive enzymes. Every single batch is third party tested for quality. Customer reviews are largely positive, customers like the high quality ingredients. There were mixed reviews on the taste including multiple complaints about the stevia aftertaste.
At a Glance
- Organic pea and rice protein
- Good mixability
- High cost per serving
- Third-party tested
When looking for the best organic protein powder, we were highly impressed with the formulation of Ora Organic Daily Superfood Plant Protein, which earns 4 out of 5 stars. This clean formula is certified USDA organic, with no artificial sweeteners or ingredients.
As plant-based proteins can cause bloating in some users, Ora also has a digestive enzyme blend to enhance absorption and reduce bloating. Each serving provides 23 grams of protein and contains only 130 calories.
Formulation: 4/5
Taste: 4/5
Solubility: 5/5
Why We Like Ora Organic Daily Superfood Plant Protein
As is the case with any of the best organic protein powders, the Ora Organic Daily Superfood Protein bears the USDA Organic seal that states it’s free of synthetic or genetically-modified organisms (GMOs). It leads the pack because of what’s inside, mainly a superfoods blend for increased vitamin and mineral intake and an enzyme blend to help with digestion.
Certified nutrition coach and former GGR performance editor Anthony O’Reilly says he’s not sure if it’s the digestive enzyme blend, but he had no bloating or gas after trying Ora Organic’s Vanilla Chai flavor. He rated the taste a 4 out of 5. “It was more chai-flavored than anything else, and I typically like my chai with a little more spice,” he says. “I still think this would be great in an iced coffee or with almond milk.
While this is a clean formulation and third-party tested, I wish they would detail an amino acid profile on the label—I especially want to know how much leucine is in a plant-based protein to ensure it’s a clinically effective dose.
Bob Iafelice, MS, RDN, LDN
Alternatives
While the formulation is excellent, this protein is very expensive, costing $2.99 per serving. With the average protein costing only $1.85 per serving, we give this a 1 out of 5 for the price per serving.
Anthony O’Reilly tested the Vanilla Chai flavor and pointed out that while the flavor is pleasant, it’s not exactly on point with the classic chai experience.
“It tasted like the type of chai you’d get at some type of hipster cafe,” says Anthony. “Which is to say, it didn’t taste like authentic chai but more like ‘chai-flavored.” I like my chai to have a little more spice. Vanilla and cinnamon were the dominant flavors.”
Overall, this is a good protein powder, but it’s quite expensive.
If you’re looking for a different all-natural protein powder that’s a bit more affordable, we recommend Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate. It’s a dairy-based product, but free of all artificial ingredients and sweeteners.

Best-Tasting Protein Powder: Nutricost Whey Protein Concentrate
Updated by: Matt Dustin, CSCS, PN1-NC
Nutricost Whey Concentrate contains 25 grams of high-quality whey protein concentrate per serving and is available in five flavors. It’s gluten-free, non-GMO, manufactured in a GMP-compliant facility, and third-party tested. Our team thoroughly enjoyed the taste, which is one of the most important factors when evaluating a protein powder.
At a Glance
- Great flavors
- Budget-friendly protein
- Whey protein concentrate
- Third-party tested
Nutricost Whey Protein Concentrate is a high-quality protein source that’s both affordable and delicious. Our testers tried both the chocolate peanut butter and vanilla flavors, and gave this formula 4.25 out of 5 for the taste. The flavor is excellent, but the presence of artificial sweeteners may leave an unpleasant aftertaste for some individuals.
At about $1.00 per serving, Nutricost Whey Concentrate is also super wallet-friendly and earns 5 out of 5 stars for the price.
Formulation: 4/5
Taste: 4.25/5
Solubility: 4.5/5
Why We Like Nutricost Whey Protein Concentrate
This budget-friendly whey protein is simple, affordable, and packed with plenty of delicious protein in each scoop.
Athletes will be happy to know that Nutricost is third-party tested, though it’s not by a major lab, so we’re giving it a 4 out of 5 in the transparency category. This could still be a great protein powder for runners and gym-goers, though.
Kate Meier, NASM-CPT, USAW-L1, CF-L1, also gave this protein 5 out of 5 stars for the solubility, saying, “It mixes extremely well, even in just a shaker cup.”
As a reminder, whey protein concentrates contain much more lactose than whey protein isolates, so it might not be the best choice for those with dairy sensitivities.
I don’t LOVE peanut butter, and I wasn’t too jazzed about trying the Chocolate Peanut Butter flavor. BUT the ‘peanuty’ flavor is just right—not too powerful and doesn’t overpower the chocolate. I really, really liked it.
Kate Meier, NASM-CPT, USAW-L1, CF-L1
Alternatives
This delicious, affordable whey protein concentrate is one of the best-tasting proteins we’ve tested, and it’s very affordable. For those looking for taste and quality on a budget, it’s hard to beat.
However, the only callout is the fact that it’s a whey protein concentrate, which contains more fat and lactose than something like a whey protein isolate. This is the main reason we only gave it 4 out of 5 stars for the formulation, and for protein users like myself who are sensitive to dairy, whey concentrates can cause some bloating and digestive discomfort.
If you’re sensitive to dairy, you may want to consider something like Dymatize ISO 100 instead—an affordable whey protein isolate that’s still available in plenty of great flavors, but has most of the fat and lactose removed for easier digestion.
Testing Breakdown
For a closer look at Nutricost Whey Protein Concentrate, here’s a detailed look at how it scored.
Vs. The Average
Here’s how Nutricost compares to the average protein powder. If you can stomach whey protein concentrate without any digestive issues, Nutricost wins in nearly every category.
Nutricost Whey Protein Concentrate | Average Protein Powder | |
| Price per serving | $0.87 – $1.28 per serving | $1.85 |
| Calories per serving | 130-150, depending on the flavor | 130 |
| Protein per serving | 25 g | 25 g |
| Available flavors | 5 | 8 |
| Third-party tested? | Yes | Yes |

Best Casein Protein Powder: Transparent Labs Casein Protein
Updated by: Matt Dustin, CSCS, PN1-NC
Transparent Labs Casein Protein provides 25 grams of protein per scoop and is extremely popular among users. This grass-fed protein powder is ideal for nighttime use, especially if you’re looking to maximize muscle growth and recovery.
At a Glance
- Formulated with grass-fed casein protein
- Mixes very well
- Strong formulation
- Third-party tested
Transparent Labs is our favorite casein protein powder because it tastes great and is more easily mixed into liquid than other options (casein is naturally thicker than whey). It earns a 4.5 out of 5 for its formulation, too, with a solid 25 grams of protein in each serving.
Beyond this casein’s yummy taste and consistency, it rated highly in our independent testing, as well. GGR worked with independent and accredited lab Ellipse Analytics to test more than 150 protein powders for label accuracy and purity. Transparent Labs’ casein was rated as “Meets Standard” overall, meaning it’s in the top 50% of samples we tested and has passed our strict quality screen.
Formulation: 4.5/5
Taste: 5/5
Solubility: 4.5/5
Why We Like Transparent Labs Casein Protein
Transparent Labs Casein protein powder is one of the best protein powders for weight loss because it digests more slowly than whey protein or any plant-based protein types, meaning it keeps you fuller for longer and can help you more easily achieve the caloric deficit that’s necessary for weight loss.
Most casein proteins are also thick, clumpy, and don’t always have the best taste. Transparent Labs breaks the mold with this casein powder, and it’s the most soluble, delicious casein we’ve tested. It earns a 5 out of 5 for taste, and a 4.5 out of 5 for solubility.
Amanda Capritto, CPT, CES, CNC, CF-L1, CSNC, says, “It mixes into a nice, thick shake or into delicious pudding! Unlike with most casein powders, I don’t find it particularly difficult to break up all the clumps with this one.”
This stuff tastes very close to Jell-O chocolate pudding out of the little plastic tubs, and I crave it.
Amanda Capritto, CPT, CES, CNC, CF-L1, CSNC
Alternatives
Casein protein serves a very specific purpose. It’s thick, slow-digesting, and often used before bed, or to stay full between meals. That said, it’s not the best protein powder to have after a workout, as it can take hours to fully digest.
At $1.99 per serving, it also costs more than the average protein powder, and earns 2.25 out of 5 stars for the price per serving.
If you’re looking for a fast-digesting protein source that uses the same high-quality ingredients with rigorous third-party testing, Transparent Labs 100% Grass-Fed Whey Protein Isolate is a fast-digesting alternative from the same brand.
Testing Breakdown
Here’s how Transparent Labs casein scored based on our testing protocols.
Vs. The Average
While it costs more and is only available in one flavor, Transparent Labs still has just as much protein and fewer calories than the average protein powder.
| Legion Transparent Labs Casein Protein+ | Average Protein Powder | |
| Price per serving | $1.99 | $1.85 |
| Calories per serving | 120 | 130 |
| Protein per serving | 25 g | 25 g |
| Available flavors | 1 | 8 |

Best Protein Powder for Muscle Gain: Optimum Nutrition 100% Gold Standard Whey
Updated by: Matt Dustin, CSCS, PN1-NC
Optimum Nutrition Gold Standard 100% Whey is a team favorite for its budget-friendly prices and taste. Our team has tried multiple Optimum Nutrition flavors, and every one is ranked a 4 or 5 out of 5.
At a Glance
- Affordable protein
- Over 20 flavors to choose from
- Contains sucralose
- Third-party tested
Optimum Nutrition 100% Gold Standard Whey is one of the most well-known, popular protein powders on the market, and has built a strong reputation for good reason. It’s affordable, packed with protein, and there’s a flavor for practically every taste preference.
Laila Ouldibbat, R.D., is a fan of the formulation, too, which she gave 4.5 out of 5 stars. For one, it contains 24 grams of protein per serving from a mix of protein sources (whey isolate, concentrate, and hydrolyzed whey protein) that come from hormone-free cows. It also contains 5.5 grams of branched-chain amino acids (BCAAs) in support of improved muscle endurance and recovery.
Formulation: 4.5/5
Taste: 4.5/5
Solubility: 5/5
Why We Like Optimum Nutrition 100% Gold Standard Whey
With 24 grams of protein in each serving, added digestive enzymes to help reduce any bloating, and over 20 flavors to choose from, this is one of the most versatile protein powders on the market. It’s a little higher in calories than a pure whey isolate, as well, making it a great choice for building muscle.
We also tested four flavors of Optimum Nutrition Gold Standard 100% Whey with an independent, accredited lab, Ellipse Analytics, for label accuracy and purity, which includes heavy metals, bisphenols, phthalates, and pesticides, and all met our quality screen.
Speaking of flavors, Optimum Nutrition currently offers 23 flavors to choose from, so you’re sure to find something you enjoy. We love to see this, as we know all too well that taste preferences vary from person to person.
For example, two of our expert testers tried the same flavor, Chocolate Peanut Butter Cup, and had mixed results. One tester said, “You should just do real peanut butter because this is too powdery,” while our other tester loved the taste, comparing it to a Christmas morning treat.
I ordered Delicious Strawberry and it’s amazing. I wouldn’t have normally picked this flavor, but my husband said this was his favorite protein back in the day and it didn’t disappoint. Even my kids liked it.
Nicole Davis, PN1-NC, CPT
Alternatives
This is an excellent choice for those looking for a high-quality protein that can support muscle growth. However, it’s not a pure whey isolate, and it’s slightly higher in calories than some other options.
It also contains artificial sweeteners, which is why we docked half a point and gave this 4.5 out of 5 for the formulation, as some prefer to consume all-natural products.
If you prefer a pure whey protein isolate that’s free from artificial sweeteners, we recommend our pick for the best overall protein powder, Transparent Labs 100% Grass-Fed Whey Protein Isolate.
Testing Breakdown
Here’s a complete breakdown of how Optimum Nutrition 100% Gold Standard Whey scored based on our protein testing methodology.
Vs. The Average
Here’s a look at how Optimum Nutrition 100% Gold Standard Whey compares to the average protein powder. As you can see from the table, it’s above average in nearly every category.
| Optimum Nutrition 100% Gold Standard Whey | Average Protein Powder | |
| Price per serving | $1.08-$1.66 (depending on flavor and container size) | $1.85 |
| Calories per serving | 120-130, depending on the flavor | 130 |
| Protein per serving | 24 g | 25 g |

Best Collagen Protein Powder: BUBS Naturals Collagen Protein Powder
Updated by: Matt Dustin, CSCS, PN1-NC
BUBS Naturals Collagen Protein is a collagen protein powder for people on the move. Not only does it mix well with most liquids, but it can also be purchased in travel packets for convenience. This collagen supplement is also certified by NSF Sport, the official third-party certification for the U.S. Anti-Doping Agency (USADA).
At a Glance
- Third-party tested
- Paleo, Keto, and Whole30 approved
- Grass-fed collagen
- Zero added sugars or artificial sweeteners
There are 18 grams of protein per scoop and 20 grams of bovine collagen peptides in BUBS Collagen Peptides, earning it a 3.5 out of 5 for formulation. It should be noted, however, that collagen doesn’t contain tryptophan, an essential amino acid, and it may not be as effective for muscle recovery as whey protein.
RELATED: Best Collagen Supplements
Instead, collagen is often used to promote healthy hair, skin, and nails, and it may be effective4 to support healthy joints. According to Laila Ouldibbat, R.D., collagen can also be used like any other protein powder to increase satiety, which is the feeling of fullness between meals.
We gave the formulation a 3.5 out of 5 because it has less protein than the average protein powder that it’s being compared to for this guide. As a collagen supplement, though, this is still one of the best options on the market.
Formulation: 3.5/5
Taste: 3.5/5
Solubility: 4/5
Why We Like BUBS NATURALS Collagen Protein Powder
Each scoop contains 20 grams of collagen peptides, including Type 1 and Type III collagen peptides. We like to see this blend, as different types of collagen peptides may support different areas of the body. Collagen peptides have potential benefits not only for skin but also for bones and joints, which is important for those looking to maintain physical strength.8
In our independent testing with Ellipse Analytics, where they tested 150 protein powders for label accuracy and purity, this product was rated as “Meets Standard” overall, meaning it was in the top 50% of samples we tested. Check out our Independent Supplement Testing Glossary for more information on what we tested for.
Our tester, Kate Meier, NASM-CPT, USAW-L1, CF-L1, added, “They have small travel packs that I took with me on a trip. I had no issues flying with them, they are single-serving so you can take it on-the-go. Maybe expensive and slightly unnecessary, but I found them to be super useful!”
It dissolves pretty well in coffee. You can see some floaties around, and when mixed in a cup of cold water, some sediment remains at the bottom. But I would still drink this every day.
Kate Meier, NASM-CPT, USAW-L1, CF-L1
Alternatives
If you’re looking for a collagen formula, this is the best one we’ve tested. However, as previously noted, collagen isn’t the best protein source for building muscle. Instead, it’s mostly used to support healthy hair, skin, and nails.
Since this was being compared to traditional protein powders, it didn’t score as well for the formulation, as collagen is an incomplete protein that’s lacking some essential amino acids.
For fitness enthusiasts who want to prioritize muscle recovery and growth, we recommend a traditional whey protein instead, like Momentous Grass-Fed Whey Protein.
Testing Breakdown
Here’s how our tester scored this collagen formula using our supplement testing methodology.
Vs. The Average
Even though collagen isn’t exactly in the same category as most whey proteins, here is how it compares to the average protein powder. It’s lower in protein, but it’s also not likely to be used as a traditional protein powder.
| BUBS NATURALS Collagen Protein Powder | Average Protein Powder | |
| Price per serving | $1.67 | $1.85 |
| Calories per serving | 70 | 130 |
| Protein per serving | 18 g | 25 g |

Best Unflavored Protein Powder: NOW Sports Whey Protein Isolate
Updated by: Matt Dustin, CSCS, PN1-NC
NOW Sports Whey Protein Isolate is an unflavored protein which delivers 25 grams of protein per serving, along with a good profile of BCAAs. This is a great budget-friendly option if you’re not concerned about taste.
At a Glance
- Unflavored whey protein isolate
- Budget-friendly, yet high in protein
- Minimal fat and carbs
- Third-party tested
NOW Sports Whey Protein Isolate has a strong formulation that earns 5 out of 5 stars, and only contains two ingredients—whey protein isolate and sunflower lecithin emulsifier, which prevents the protein from separating. There are no artificial flavors, sweeteners, or other additives in the unflavored version, making it one of the best unflavored protein powders.
This neutral protein has a mild taste that’s easily masked when added to a flavored beverage, making it a versatile protein powder that earned 4 out of 5 stars for the taste. It’s not entirely unflavored, as whey protein is derived from milk, but the flavor is easy to cover with other ingredients.
Formulation: 5/5
Taste: 4/5
Solubility: 4.5/5
Why We Like NOW Sports Whey Protein Isolate
Now Sports Nutrition Whey Protein Isolate contains two ingredients: whey protein isolate and a minimal amount of sunflower lecithin emulsifier (which prevents the protein from separating). That’s it.
Lauren Strong, CPT, gave this a 4.5 out of 5 for solubility, saying, “No issues blending; in a shaker cup by itself, it dissolves pretty well. And then in a blender, you don’t notice it at all.”
Laila Ouldibbat, R.D., noted that the powder is free of most notable allergens, including corn, egg, soy, and gluten. It’s also safe for those who follow kosher and halal lifestyles, which she says is “extremely rare” in protein powders.
It’s available in both Creamy Chocolate and Creamy Vanilla, but we’ve only tested the unflavored variation at the time of writing.
We also love that it’s third-party tested by Informed Sport, one of the leading testing companies.
If you want something to make smoothies with or bake with, this is a good option. It doesn’t have a taste that would overpower any other flavors you use it with.
Lauren Strong, CPT
Alternatives
While this is one of the purest whey isolates on the market, it’s also unflavored. Many protein fans will enjoy this, as it’s easy to add to smoothies, yogurt, oatmeal, or flavored liquids.
That said, if you’re mixing it with water, you may not love the taste of unsweetened, unflavored whey protein. Lauren states, “It definitely has a ‘whey’ taste, which is not that good. This is certainly not gag-worthy, but I did mix this with water to get the full non-flavored effect.”
If you’re after delicious flavors, we think Nutricost Whey Protein Concentrate is the best-tasting protein powder we’ve tested.
Testing Breakdown
Here’s a breakdown of how we calculated our final score for NOW Sports Whey Protein Isolate.
Vs. The Average
As you can see from the table below, NOW Sports Whey Protein Isolate beats the average protein powder in nearly every category, making it an excellent choice for those who want an unflavored protein powder.
| NOW Sports Whey Protein Isolate | Average Protein Powder | |
| Price per serving | $0.66-$1.38 (varies by container size) | $1.85 |
| Calories per serving | 110 | 130 |

Best Protein Powder for Weight Loss: Ritual Essential Protein Daily Shake
Updated by: Matt Dustin, CSCS, PN1-NC
Ritual’s Essential Protein Daily Shake has 20 grams of protein per serving and 150 milligrams of chlorine (to support brain and nervous system function).
What our tester says:
“I tried this two ways – in a blender cup with water, and in a smoothie with strawberries and blueberries. Even just with water, this has a nice taste.”
At a Glance
- Formulated with pea protein
- 115 calories per serving
- Somewhat expensive
- Third-party tested
With only 115 calories per serving, Ritual Essential Protein Daily Shake is a great option if you’re looking for a protein powder for weight loss. Available in just one flavor (Vanilla), you can mix it into Greek yogurt or simply toss a scoop in your favorite shaker bottle for a low-calorie, high-protein snack to satisfy your cravings.
Kate Meier, NASM-CPT, USAW-L1, CF-L1, gave this 4 out of 5 stars for the taste, an impressive score for a plant-based protein formula.
“I tried this two ways—in a blender cup with water, and in a smoothie with strawberries and blueberries,” explains Kate. “Even just with water, this has a nice taste. It’s not super plant-y or hemp-y like some plant-based proteins are.”
This plant-based formula is also free from any dairy products, making it a good choice for those with lactose intolerance.
Formulation: 5/5
Taste: 4/5
Solubility: 5/5
Why We Like Ritual Essential Protein Daily Shake
This plant-based protein is made with high-quality ingredients, no artificial sweeteners, and is low in calories, making it a good choice for those looking to follow a nutrition plan focused on weight loss.
Of course, plant-based protein powders often have the disadvantage of being low in certain types of amino acids—case in point, pea protein lacks enough methionine to be considered a “complete” protein source (a protein with all nine essential amino acids needed for muscle growth).12
Ritual Essential Protein Daily Shake gets around this problem by adding more methionine to the powder, providing 20 complete grams of protein per serving. It earns a 5 out of 5 for its formulation.
The taste is definitely detectable, but not overly strong. It also has a shockingly great consistency.
Kate Meier, NASM-CPT, USAW-L1, CF-L1
Alternatives
While this protein is low in calories and gentle on the stomach, it’s pretty expensive. At $2.93, this is one of the most expensive powders we’ve tested, and only earns 1 out of 5 for the price per serving.
We recommend this protein for those focused on weight loss, but if you’re on a tight budget, there are certainly other options to consider.
For another low-calorie alternative, we recommend trying Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate. It’s made with dairy, but it’s also free of artificial sweeteners and ingredients, and it’s a little easier on the wallet.
Testing Breakdown
Here’s how Ritual Essential Protein Daily Shake scored based on our testing methodology.
Vs. The Average
Here’s a look at Ritual Essential Protein Daily Shake versus the average protein powder. It’s quite expensive, but similar to the average in other categories.
| Ritual Essential Protein Daily Shake | Average Protein Powder | |
| Price per serving | $2.93 | $1.85 |
| Calories per serving | 115 | 130 |
| Protein per serving | 20 g | 25 g |
| Available flavors | 1 | 8 |
| Third-party tested? | Yes | Yes |

Best Protein Powder for Smoothies: Sports Research Whey Isolate
Updated by: Matt Dustin, CSCS, PN1-NC
Sports Research whey protein isolate has 25 grams of protein per serving and just 150 calories. It’s third-party tested, too. Although there are only two flavors available, our testers think it’s worth a try.
What our tester says:
“There’s no weird aftertaste, and I had zero issues with bloating after drinking it.”
At a Glance
- Whey protein isolate
- Fairly priced
- Only two flavors
- Third-party tested
With high mixability and a mild flavor, this is our pick for the best protein powder for smoothies. It has a short ingredient list that’s non-GMO, gluten-free, and soy-free, each serving contains 140 calories and 25 grams of protein. Sweetened with Steviol glycosides (a low-calorie natural sweetener derived from the stevia plant), our team gave the formulation a rating of 4.5 out of 5.
This protein powder is also third-party tested by Informed Choice, which earns it a perfect rating for third-party testing. It’s a whey isolate, which means it’s easy to blend, and our testers said it has a flavor that’s not overpowering, giving it 4.5 out of 5 for the taste.
Formulation: 4.5/5
Taste: 4.5/5
Solubility: 4/5
Why We Like Sports Research Whey Isolate
First and foremost, we love the formulation. There’s no gluten or soy, and each serving contains 140 calories and a full 25 grams of protein, which meets the industry average. This protein powder is also third-party tested by Informed Choice, which earns it a perfect 5-out-of-5 rating for third-party testing.
Our testers enjoyed the flavors, too, and we found them to be fairly neutral without being too overpowering. This is a great protein powder to mix into smoothies, oatmeal, or Greek yogurt.
Amanda Dvorak, CPT, CNC, tested this protein and gave it 4 out of 5 for solubility.
“I shook it in a blender bottle for about 10 seconds, and it dissolved completely,” says Amanda. “It has a super smooth texture when you drink it, but it does settle at the bottom of the bottle when it sits for a while.”
In our experience, protein powders blended into smoothies aren’t likely to settle unless the whole thing melts, which is why we like Sports Research protein for our smoothies.
Sports Research added 1,000 milligrams of extra leucine to this formulation to promote greater muscle-building potential. Each serving contains an impressive 6.9 grams of BCAAs, which may promote muscle recovery and growth.
Bob Iafelice, MS, RDN, LDN
Alternatives
With great taste, formulation, and an affordable price tag, this is a great choice for anyone looking to boost their smoothies with extra protein. It’s only available in two flavors, but if you’re adding this to a smoothie, you probably don’t need more than chocolate or vanilla.
We still give the taste 4.5 out of 5 stars, and this protein truly didn’t have any noteworthy callouts. That said, we know that many veteran protein powder users may be tired of chocolate and vanilla.
For those who want a little more flavor variety, Dymatize ISO 100 is another great choice with plenty of flavors to choose from.
Testing Breakdown
Let’s take a closer look at exactly how we scored Sports Research Whey Isolate.
Vs. The Average
If you’re on the fence about trying Sports Research Whey Isolate, here’s how it compares to the average protein powder. It’s very affordable, though it has limited flavors and slightly more calories than the average protein.
| Sports Research Whey Isolate | Average Protein Powder | |
| Price per serving | $1.42-$1.99 | $1.85 |
| Calories per serving | 140 | 130 |
| Protein per serving | 25 g | 25 g |
| Available flavors | 2 | 8 |
| Third-party tested? | Yes | Yes |

Other Protein Powders We Researched
It might be hard to believe, but there are a few protein powders we came across during our research that didn’t make the mark. Hey, after trying more than 150, you’re bound to run into some that just don’t make the cut.
- Muscle Milk Genuine Protein Powder: We noted in our full Muscle Milk review that this protein powder is a great choice for people who are more active than the everyday person due to the higher caloric, carb, and fat content. If you fit that description, this might be the best protein powder for you.
- Bob’s Red Mill Almond Protein Powder: This plant-based protein powder is produced by Bob’s Red Mill, a company that primarily makes baking ingredients. While it does have 20 grams of protein per serving, the fat and carb content is higher than we’d like to see, and the per-serving cost is high at $1.85. It’s also only made from ground almonds, which are an incomplete protein.
- BSN Syntha-6: A mixture of whey protein and casein protein, BSN Syntha-6 is a fairly affordable protein powder (around $1.50 per scoop) that some might consider a meal replacement shake (each serving is 200 calories with a moderate amount of carbs and fats). It has a longer ingredient list than we would like and can contain up to 4 grams of added sugar (depending on the flavor).
- Ka’Chava Meal Replacement: $4.67 per serving…no, that’s not a typo. Customers were impressed with the taste and those trying to lose weight found it to be a suitable meal replacement. It also has the advantage of being higher in micronutrients (vitamins and minerals) than other protein supplements. Our Ka’Chava review has our full thoughts.
- Bare Performance Nutrition Whey Protein: Anthony O’Reilly, a certified personal trainer and nutrition coach, tried Bare Performance Nutrition Whey Protein years ago. “I recall being a big fan of their product when I first got into weightlifting,” he says. The protein powder is a whey and casein blend, so it’s a little thicker than most whey proteins and is perfect for protein sludge (my favorite recipe actually comes from BPN founder Nick Bare). The flavors, as I recall, are all great, but if I had to pick just one I’d go with Blueberry Muffin.
- Orgain Grass-Fed Whey Protein: Many of Orgain’s protein powders are organic, however, this one is not and it contains more carbs and fats than we typically like to see in a protein powder. Our Orgain Grass-Fed Whey Protein Review has our complete breakdown.
- Ghost Whey Protein: Ghost Whey Protein comes in a lot of fun flavors, such as an officially-licensed Chips Ahoy option, but as we note in our Ghost Whey protein review there are a few things that kept it from making our list (such as the price per serving).
- Bloom Whey Isolate Protein: This protein powder is a TikTok trend. Our Bloom protein review looks into whether it’s worth the hype.
- SEEQ Protein Powder: You’ve probably seen this clear whey protein isolate and thought, “Is it any good?” Our SEEQ protein powder review answers that question.
How We Picked and Tested the Best Protein Powder
There are more than 400 brands creating what they claim to be the best protein powder, according to marketing analysis firm Lumina Intelligence5. We’ll say right now that we didn’t try nearly that many, but we were able to narrow down our selections by using our GGR supplement testing methodology.
We also worked with a registered dietitian to develop our protein-specific testing method, which accounts for a number of factors.
Protein Content
Obviously, a good protein powder should have a high amount of protein—our top picks have protein content ranging from 19 to 30 grams. In order to score a perfect 5/5 for protein content, we insist that a supplement has at least 18 to 20 grams of protein per serving. Some protein powders contain substantial amounts of other macronutrients (fats and carbohydrates)—we call that out because many people who drink protein shakes are looking to maximize their protein intake.
Protein Source
The source of the protein matters because we recommend complete proteins. Therefore, we research whether the protein powder comes from whey, casein, egg white, or plant-based sources (such as pea protein, rice protein, chia seeds, or brown rice). If the protein comes from an incomplete source, are there additional ingredients to make it a complete source?10 If not, the product would score low with our testers.
Carb and Fats
Amino Acids
We also wanted to make sure each selection had a low or moderate carb and fat content (it should, after all, be mostly protein). If a protein is loaded with carbs, it could be considered one of the best mass gainers instead of just a protein powder for weight gain.
Did each protein powder have all nine essential amino acids? This is especially important for plant-based protein sources as every one, with the exception of soy and technically pea, is an incomplete protein. Companies work around this by using complementary proteins, which involve combining two or more protein sources to obtain all essential amino acids in their supplement.11
Digestibility and Side Effects
Solubility
We had each product tester report back on any potential side effects. For example, how well did the protein powder digest? Did it cause any digestive issues or bloating? You will often find enzymes in protein derived from dairy sources to help with the breakdown.
We personally mixed protein powders with water, with milk, or milk substitutes to test for solubility. Our testers put the powders in a shaker cup and used blenders to assess: How well does this product dissolve in the suggested amount of liquid? Does it separate after a few minutes? To earn a 5 out of 5, a protein powder has to dissolve completely, with no floaters or clumps, and no separation after resting for a few minutes.
Flavor and Taste
Price Per Serving
Did it taste good? We know taste is subjective, so we had multiple people try many of the options on our list, and we also consulted customer reviews. Products that earn high marks here get favorable taste reviews from both customers and our internal testers. Also, while we wouldn’t rate a product low for a lack of flavor options, we do give credit to companies that offer customers a number of flavors.
The price per serving can range from $1.25 on the low end to upwards of $2 on the high end. Protein powders with a more affordable cost per serving were rated higher than those that cost $2 or more per scoop.
Ingredients
Third-Party Testing
Protein powders get bonus points for having a short ingredients list. Things like artificial sweeteners and fillers have potential negative health impacts, and we don’t want large amounts of them in a protein supplement.9 On the flip side, protein powders often come with additional ingredients, such as creatine, digestive enzymes, or probiotics.
Since dietary supplements are not approved by the FDA, having an independent third-party lab verify that what’s on the label is what’s in the protein powder is super important, especially for athletes. We favored companies that had their products tested for heavy metals, toxins, or banned substances.
Benefits of Protein Powder
Wondering why you should consider purchasing or using protein powder? Here are a few reasons:
- It’s convenient. It’s much easier and quicker to chug 8 ounces of protein powder (mixed with the liquid of your choice) than it is to defrost, prepare, cook, and eat a piece of meat (not to mention the clean-up). It may not be as portable as a No Cow protein bar, but at least it’s quick.
- It’s shelf-stable. Does protein powder expire? Well, it definitely doesn’t last forever, but protein powder can last a surprisingly long time on your shelf if properly sealed and kept out of direct sunlight.
- It helps build muscle1. There are mountains of evidence supporting the use of protein powder to help build muscle.
- It can support weight loss efforts.3 Protein powder can also be used for those who are on a weight loss plan. Protein requires more energy to digest than do fats and carbohydrates, leading to a higher calorie burn.
Dr. Raj Dasgupta, MD, FACP, FCCP, FAASM, GGR’s Chief Medical Advisor, also pointed out that all genders can enjoy the health benefits from protein powder, even if your goal isn’t to build muscle.
“Protein powder may help both men and women build muscles, manage weight, and stay healthy,” says Dr. Dasgupta. “Men, who usually have more muscle, might require more protein, but protein powder can be a good option for anyone looking to improve fitness, recover after workouts, and stay healthy.”
Buying Guide: What to Look for in Protein Powder
Protein powders will try to draw you in with colorful labels and attractive claims, but here’s what you should actually look for when you’re trying to decide which is the best protein powder for you.
Calorie Content
This might change depending on your fitness goal. For example, if you’re looking to bulk (or add muscle), you’d want more calories than someone whose main goal is weight loss.
Protein Content
You should generally look for a protein powder with at least 20 grams of protein per serving to help build muscle and keep you full.
Protein Type
Most protein powders come from whey protein, but there are different protein types, the two most common alternatives being casein protein powder and plant-based protein powders. Casein is also a dairy-based protein that digests more slowly than whey, which is why athletes will often take it before going to sleep.
RELATED: Best Recovery Protein Powder
There are also meal replacements, sometimes called mass gainers, which contain an entire meal’s worth of protein, carbohydrates, and fats. Mass gainers are primarily used for people looking to add muscle mass, but can also be utilized by those trying to reduce their body weight.
Taste
Find a flavor you like. Most protein powders will come in dessert-themed flavors, though there are now companies producing more fruity flavors that mix well with water. You can also choose unflavored protein powders if you wish to bake with it or add it to other foods without impacting the taste.
Price
Self-explanatory, but find a protein powder that works for your budget. Most of the best protein powders will be around $1.50-$2.00 per scoop with 30 servings, though you can find more affordable protein powders for around $1.10 per scoop.
Fitness Goals
Protein is obviously essential for building muscle, but how much you need depends on your fitness goals. For people on a cut, you’ll want a whey isolate for an extra boost of protein without extra fat or carbs. If you actually want those extra calories while on a bulk, go for a whey concentrate or a full-on mass gainer to make your shakes more of a meal. Before making any purchase, start by looking at what you actually want your protein powder to accomplish. Chances are, there’s a perfect fit out there.
Third-Party Testing
Remember to always check the third-party testing credentials of your protein powder before you buy. If the product has been tested, it will typically be noted on the packaging and on the product website. Check whether the company is certified by NSF, Informed Choice/Sport, or other reputable organizations, and whether the test results are available on the brand’s website. These tests will show results for a range of potential contaminants in your protein powder, including heavy metals, harmful additives, and banned substances.
Allergens and Dietary Preferences
Along with third-party testing, you’ll want to research all potential allergens in any protein powder you’re considering purchasing. This includes obvious ones like wheat, nuts, and milk, along with shellfish, tree nuts, and fish oil. Even if it doesn’t seem like a protein powder would include any of these ingredients on the surface, there’s always the potential for cross-contamination at the manufacturing facility.
You might have to avoid certain brands depending on the type of allergy you have. In other cases, like with lactose intolerance, you could just opt for a dairy-free powder. These plant-based powders typically come from rice, pea, or pumpkin protein and are just as effective as dairy-based powders. Remember, plant-based powders should be third-party tested just like dairy powders, so don’t let your guard down.
What to Avoid in Protein Powders
Protein powders are going to mostly be protein, but some formulations will have other ingredients added, too. Here are a few ingredients to look for—or in some cases, look out for.
Sweeteners
Unflavored protein powders are usually great to add to baked goods or flavorful smoothie drinks, but they aren’t going to be great in a shaker cup with water or milk. Flavored protein powders will usually have some sort of sweetener added to help with the flavor.
Sweeteners can be anything from natural ingredients, like sugar or zero-calorie stevia, or it can be an artificial sweetener, like sucralose.
“Despite what the media says, RDs are not entirely convinced that artificial sweeteners are bad for your health,” says Destini Moody, RD. “That said, people should be wary of sugar alcohols in their protein powderas these are low-calorie sweeteners that do not break down well in the gut and excess consumption can cause gas, stomach cramps and diarrhea.”
Filler Ingredients
While some additives and ingredients are used to help preserve the protein powder, other ingredients are there just to help fill up the tub or container. Avoid filler ingredients like maltodextrin or cornstarch, and check the label. You also want to avoid powders that are loaded with excess sugars or thickeners like xanthan gum that may cause digestive issues.
If possible, avoid protein powders that have a laundry list of ingredients, aiming for options that keep it simple. You’ll also want to check for any allergens and, if applicable, whether your protein powder is kosher or halal.
Amino Acids
Some protein powders have added amino acids, which can be a nice addition. However, remember that protein has essential amino acids, and the added amino acids are usually non-essential. So, make sure that you’re still getting a good amount of protein per serving. Creatine is also sometimes added, but the same rule applies. Plus, you can usually find quality creatine at a good price on its own.
Caffeine
A common flavor of protein powder now is based on coffee, with Cappuccino, Mocha, or Latte flavors being prevalent in many brands. Consumers should be aware, though, that these protein powders can have caffeine added to them. If you’re sensitive to caffeine or looking to cut back, you should opt for other flavors. Make sure to check the ingredient label to see if it is actually in the powder, too.

Carbs and Fat Content
Although there are times when carbohydrates should be paired with protein, specifically after intense training sessions, most people should look for a protein powder that’s mostly, well, protein. There should be minimal carbs and fats, ideally under 5 grams of each.
Untested Supplements and Proprietary Blends
Athletes should consider protein powder that has Informed Sport, Certified for Sport, or any third-party certifications. These marks show that they’ve been third-party tested for banned substances, heavy metals, and toxins.
For instance, brands that scored highly in our own independent testing of more than 150 protein powders with an independent accredited lab, Ellipse Analytics, got extra points in our book. Ellipse Analytics analyzed batches of protein powder to check for the presence of potential contaminants, like:
- Bisphenols and phthalates: chemical compounds used to make plastic products
- Pesticides: chemicals used on crops and plants for pest control and the treatment of weeds
- Heavy metals: metals such as lead that may negatively affect your health with chronic exposure, according to a November 2022 study6
Transparency also plays a part in this. Does the company provide COAs, not use proprietary blends, and generally seem very upfront about what’s used in their protein powder and why?
Lastly, avoid any protein supplement that has proprietary blends. These blends are a mix of different ingredients, and manufacturers aren’t required to disclose how much of each ingredient is in the blend—oftentimes, companies can underdose ingredients.
Lead and Other Heavy Metals
In October 2025, Consumer Reports published an article about the lead levels in several popular protein powders. Of the 23 powders the outlet tested, two-thirds contained “more lead than [Consumer Reports’] food safety experts say is safe to consume in a day—some by more than 10 times.” The plant-based options averaged around nine times the lead levels found in their dairy-based counterparts.
Consumer Reports’ food safety experts say 0.5 micrograms of lead per day is the maximum dosage they consider “safe,” a figure based in part on those set by California’s Proposition 65 law but using a different methodology to determine risk. Conversely, the United States Food and Drug Administration’s (FDA) interim reference levels (IRLs) for lead are 2.2 micrograms per day for children and 8.8 micrograms for adults.
According to an archived page on the FDA website, an IRL “is a benchmark the FDA may use to determine if the amount of exposure to the contaminant in food is a potential health concern.” The FDA states that these IRLs are “nearly ten times lower than the amount of lead intake from food that would be required to reach the CDC’s blood reference level.”
Though studies have shown that the amount of lead found in protein powders isn’t enough to impact your health on its own13, it’s still something you’ll want to research before making a purchase. This is especially important since you also have to account for trace amounts of lead found in all the food you eat throughout the day.
We previously reached out to Dr. Sean Callan, a neuroscientist and the CEO of Ellipse Analytics, an independent lab that GGR used for third-party supplement testing. He explained how lead and other heavy metals are absorbed by plants and then passed on to animals and humans who eat them, which explains why plant-based powders ranked so high for lead content.
“It is the position of most major medical authorities, including the American Medical Association, the U.S. Food and Drug Administration, and the World Health Organization, that there is no safe level of lead,” according to Dr. Callan. “As these metals occur naturally, achieving ‘absolute zero’ is not possible, but seeking out products that have been tested by a third party is a good way to reduce your overall exposure.”
Studies show that adults average between 1.7 and 5.3 micrograms of lead exposure from food per day.14 Even if you’re comfortable with the amount of lead potentially found in your protein powder, you should look at those numbers as part of a whole.
The best way to get peace of mind is to go to the supplement company directly for more information. Legion, for example, utilizes Labdoor, an independent third-party lab, to test its products for heavy metals, allergens, and assorted contaminants. Once the results are in, the company posts them online for visibility’s sake.
Types of Protein Powder
Even though we have our pick for the best protein powder, there are many people who may disagree due to dietary or religious reasons—there are some religions that prohibit the consumption of dairy. No worries, as there are many different types of protein powder supplements to help you reach your health and wellness goals.
Whey Protein Powder
Whey protein powder is the most common type of protein powder, and it comes from whey (shocking, we know). Whey is the liquid left behind after milk has been processed and is used in multiple applications, such as cheese-making or producing protein powder.
The pros of whey protein (which may sometimes be called whey protein concentrate) are that it’s cheap and readily available, though people with dairy sensitivities may find it difficult to digest. In fact, people who are able to eat or drink milk-based products sometimes struggle with whey protein powder (it can result in some rumbling down under, if you catch our drift). Luckily, there are two other types of whey protein powder:
- Whey protein isolate: Whey protein isolate is simply whey protein that’s undergone additional filtering to remove much of the lactose (aka sugars), which results in a lower-carb, lower-fat protein powder that’s also easier to digest than normal whey protein.
- Whey protein hydrolysate: This whey protein has been pre-digested through a special process that increases the rate of absorption.
Casein Protein Powder
Casein is another byproduct of the cheese-making process, and while it’s not nearly as popular as whey protein, it contains just as much protein and micronutrients. It’s made by adding a curdling agent to milk, which then becomes lumpy. Those curdles are then either made into cheese or casein protein powder (after being dehydrated and processed, of course).
You’ll often see casein protein powder in meal replacement shakes for two reasons: It’s thicker than whey protein and digests more slowly. It’s more like a pudding than a shake, which will give your body the feeling that you’re eating more food than you actually are. And because it’s digested more slowly than whey protein, it’s a great type of protein to take before going to bed or when you know you might not be able to eat for a few hours.
Plant-Based and Vegan Protein Powders
Plant-based or vegan protein powders are dairy-free alternatives that source their protein from soy, plants, or other food sources. Here is a list of the most common plant-based proteins:
- Soy
- Pea
- Hemp
- Lentil
- Chia Seed
- Pumpkin Seed
- Brown Rice
If you’re looking for a vegan or plant-based protein powder, make sure to pay extra attention to the amino acid profile. As we discussed earlier, a protein needs nine of the essential amino acids to be a complete protein and aid in muscle growth or satiety (the feeling of being full). Soy protein powder and (technically) pea and hemp are complete plant-based protein sources, whereas other popular options like rice protein are not.
Does that mean plant-based and vegan protein powders don’t work? Not necessarily, since they may use complementary proteins—basically, a company will add rice protein and hemp protein since one may have the essential amino acids that the other lacks.
Some of the best protein powders have their full amino acid profile on the label, so if you’re a plant-based lifter, be sure to look for this on the tub or the company’s website.
Pea Protein Powder
Pea protein powder is a plant-based protein source created from yellow peas and is very high in micronutrients. Technically, it contains all nine essential amino acids, so it’s considered a complete protein, but it is low in methionine. It’s also not as bioavailable as other protein types.
Egg Protein Powder
Egg protein powder comes from eggs, and while it can be a great option for those who can’t drink dairy, we should warn you that egg protein powder often comes with an unsavory taste and smell.

Meal Replacements and Mass Gainers
Meal replacement shakes often have more calories and protein (along with additional carbs and fat) than your standard protein powder because they’re made to mimic an entire meal’s worth of fuel. These are used by people who are trying to lose weight or those who don’t have enough time to eat a full plate of food.
Mass gainers are a type of meal replacement shake used by powerlifters or bodybuilders who are trying to put on as much weight as possible, and as a result, contain thousands of calories. Some mass gainers contain more calories and protein in one scoop than some people drink in an entire day, and they should only be used under the supervision of a dietary professional.

Clear Whey Protein Isolates
A relative newcomer to the protein powder scene, clear whey protein isolates have been hydrolysed to be much more soluble and clear than regular protein shakes. The best clear whey protein drinks have a juice-like taste, rather than the milk-forward flavors you see in supplement stores, and may be a good choice for anyone with lactose sensitivities or anyone who prefers a more refreshing post-workout drink.
How to Take Protein Powder
Purchasing the right protein powder for your fitness goals is the first step. Next, you have to figure out how you want to take it. You could try the path of least resistance and simply scoop some into a shaker bottle with water or your favorite dairy/non-dairy milk.
For a bigger nutritional punch, you could blend the powder with ice, your choice of liquid, and some fruit to make a protein smoothie. If you’re tired of cleaning blenders and shaker cups, you could also mix protein powder into oats, yogurt, or incorporate it into a muffin recipe. The sky’s the limit here.

Best Protein Powder FAQs
Which brand is best for protein powder?
The best brand of protein powder should offer high-quality ingredients without a lot of junk or fillers, have a sufficient amount of protein per serving, and be third-party tested for banned substances and potential contaminants. It’s even better if the company discloses the lab results. Some of our favorite brands that fit most—if not all—of these criteria are Transparent Labs, Legion, Sports Research, and Momentous.
How much protein powder can you have per day?
Protein powder is a supplement, meaning it supplements your overall diet. The majority of your calories and protein should come from whole food sources like meats, plants, and dairy. That said, protein powder is a cost-efficient and convenient way to increase your protein intake and can be taken 1-2 times per day with no adverse side effects.
If you have any concerns, we recommend speaking with a healthcare professional.
What is the best way to use protein powder?
There are several ways to use protein powder. After a workout, you can mix a scoop with water or milk (dairy or plant-based) in a shaker bottle for a quick, easy post-workout treat. You can use it to increase the protein content of your favorite breakfast foods and baked goods, like pancakes or cookies. When you’re crunched for time and can’t cook a meal, you can blend it into a smoothie with fruit, vegetables, and nut butter for a meal replacement shake.
How long does protein powder last?
Most protein powders can last between 9-18 months depending on how it’s stored (whether there’s a tight seal), the temperature (humidity can cause it to clump), and the powder itself. Most supplements have an expiration date on the container. If the powder smells bad or looks weird, don’t consume it.
