Best Collagen Supplements (2023): 15 Dietitian-Recommended Options to Support Healthy Aging

If there’s one thing that’s certain in life, it’s that time goes by whether we want it to or not… Oh, and the signs of aging can start to surface with each passing year, mainly due to less collagen naturally produced by the body. 

While we can’t resist the future, what’s a gal and guy to do? For starters, we can prioritize a healthy lifestyle filled with high-protein foods and consider supplementing with collagen.

But with hundreds of collagen products on the market, how and which do you choose? We personally tested and analyzed roughly 30 products to find the best collagen supplements.

Myself, as a registered dietitian, along with Garage Gym Review’s team of competitive athletes, certified nutrition coaches, and personal trainers used each of these products ourselves and analyzed the ingredients, dosages, formulation, taste, cost, and other aspects to find the best. We mixed them into cold water and coffee to assess solubility, and analyzed the types of collagen used to assess the real effects the product could have.

What We Know About Collagen

Collagen¹ is the most abundant and important protein in the body. Its primary role is to provide strength, structure, and support to the bones, skin, muscles, tendons, cartilage, nails, and other organs. 

Of the 20 amino acids in the body, collagen is produced mainly from glycine, proline, and hydroxyproline. However, whereas collagen is rich in protein and amino acids, it is not considered a complete protein because, as mentioned above, it lacks tryptophan. This means that although it’s beneficial, collagen protein shouldn’t be counted toward your daily protein intake goal.

There are 28 known types of collagen², but types I through V are the most abundant (especially type I) and researched. Types I, II, and III also dominate collagen supplements, but we’ll quickly run through the top five: 

• Type I: the most prevalent type of connective tissue and mostly found in skin, bone, teeth, tendon, ligaments, and organs
• Type II: present in cartilage and supports the joints
• Type III: most common in the skin, muscle, and blood vessels 
• Type IV: found in some layers of the skin
• Type V: present in hair, cell surfaces, and placentas

Collagen is mostly sourced from animal products that contain connective tissue—like bovine (cows), marine (fish), porcine (pig), and poultry (chicken). And as you’ll soon notice, the collagen source widely dictates its collagen type, such as bovine being concentrated with types I and III collagen.

Collagen is found in whole foods, such as bone broth. In supplements, collagen is commonly formulated into collagen peptides. 

Collagen vs Collagen Peptides

The biggest difference between collagen and collagen peptides is their size. Think of this similarly to whey protein powder: While whey comes in isolates and concentrates, both forms still contain whey protein.  

RELATED: Best Protein Powder

Collagen peptides, also known as hydrolyzed collagen, undergo hydrolysis and are broken down into smaller, more bioavailable forms. Collagen peptides also have a very low viscosity, which improves mixability and makes them a great dissolvable dietary supplement—like in our top picks.

GGR Score: 4.3

Product Highlights

• No artificial sweetener, colors, or preservatives
• Formulated with grass-fed bovine collagen peptides
• Claimed to help eliminate visible signs of skin aging like sagging and wrinkles
• Made with minimal ingredients

Pros & Cons

Pros

• Worldwide shipping
• A good amount of positive reviews
• Easily mixable in cold or hot beverages

Cons

• Only 10 g of protein per serving
• Low doses of collagen compared to other brands
• Doesn’t include vitamin C, which can help with absorption
• Only comes in 1 flavor

Bottom Line

Transparent Labs Grass-Fed Collagen Hydrolysate is a collagen rich in type I and type III collagen peptides made without artificial sweetener, colors, or preservatives.

Transparent Labs Grass-Fed Collagen supplies 11 grams of hydrolyzed collagen and 10 grams of protein sourced from grass-fed bovine cattle. As a great source of types I and III collagen, it may combat the signs of aging like wrinkly skin, muscle aches, and joint pain (pretty much all the reasons you want to take collagen in the first place).

Amanda Capritto, GGR senior staff writer and certified sports nutrition coach, has used this collagen a number of times and in a number of ways. She recommends mixing it with milk, coffee, or in a smoothie; basically, anything other than water. “It’s not bad, but it kind of tastes like watered down chocolate milk (when mixed with water). I also mixed it with almond milk, which significantly improved the taste!”

While it only comes in a Chocolate and Unflavored options, you can still rest easy knowing there’s never any “artificial junk” with any Transparent Labs products. Instead, the hydrolyzed collagen is formulated with more natural ingredients like cocoa powder and stevia. It’s also a great stand-alone that mixes well in liquids or can be added to smoothies and other recipes to boost protein and collagen. 

The Transparent Labs Grass-Fed Collagen scored a perfect 5 out of 5 on our solubility rating. Amanda says that it “dissolves so well, it’s a little scary.”

“The water became clear, but brown (see-through brown?) when mixed with water. It doesn’t feel grainy and I didn’t even notice any chunks when mixed with plain water. The stuff is virtually unnoticeable when mixed with another powder, like protein powder.”

Like all Transparent Labs products, the grass-fed collagen hydrolysate powder is third-party tested. You can even view its Certificates of Analysis and Composition on the main site, aligning perfectly with the brand’s commitment to transparency.

Product Highlights

• 10 g collagen per serving
• Type 1 and Type III bovine collagen
• Derived from grass-fed, pasture-raised bovine
• No added sweeteners or artificial flavors
• Subscribe-and-save option

Pros & Cons

Pros

• Under $1.50/serving
• Sourced from grass-fed, pasture-raised bovine
• Blends well in coffee and other drinks
• Third-party tested

Cons

• One serving is two scoops
• Only 30 servings per container

Bottom Line

Swolverine Collagen Protein is an affordably priced product for those looking to supplement their diets with collagen. It delivers 10 grams of collagen per serving, which is sourced from grass-fed, pasture-raised bovine.

Swolverine Collagen Protein is a great unflavored option because it is truly unflavored. GGR head of content and self-proclaimed collagen enthusiast personally tested this product to determine if there is any taste.

“This is unflavored, and it really is unflavored,” Kate says. “I couldn’t detect any hint of it in my coffee or when I mixed it in water.” She gave Swolverine a 5 out of 5 for its taste (well, its lack of taste, actually).

This collagen features one powerful ingredient: grass-fed and pasture-raised  hydrolyzed bovine collagen peptides. Sneak this high-quality collagen in any hot or cold drinks—such as water, coffee, or smoothies—or soups and baked goods.

There are reviews that say that this dissolves well, but Kate says don’t expect it to be perfect. “This doesn’t dissolve perfectly in coffee or in water, but it dissolves enough that I can drink it without inhaling chunks of it,” she says.

Kate strongly feels it would be a great option for collagen beginners or those who truly don’t want to taste their collagen supplement.

One 10-gram serving, which is two scoops, provides 10 grams of grass-fed and pasture-raised collagen peptides, making it a pure source of collagen free of hormones and antibiotics. Naturally, as a single-ingredient collagen formula, it’s free of sugars, artificial sweeteners, additives, and fillers. 

Like all Swolverine products, its collagen peptides are third-party tested and made in the U.S. in an NSF cGMP facility. COAs of each product, including the Collagen Protein, are available on the company website.

Best High-Dose Collagen Supplement: Bulletproof Collagen Peptides

Good for: Bumping up your overall daily collagen intake

Best High-Dose

Bulletproof Collagen Peptides

GGR Score: 4.5

Check Price

Product Highlights

• Each serving provides 18 g of protein in the form of amino acids and 20 g of hydrolyzed collagen
• Bulletproof only uses collagen types I and III in science-backed doses
• Formulated to promote joint flexibility and skin elasticity
• Supports bone strength and skin hydration
• Ethically sourced
• Available in unflavored, vanilla, and chocolate

Pros & Cons

Pros

• Mix with hot or cold drinks
• Mixes well
• Convenient
• Science-backed doses

Cons

• Unflavored option may leave an aftertaste

Bottom Line

Bulletproof’s Collagen Peptides powder is an effective and easy way to add high-quality collagen type I and III into your diet.

Providing 18 grams of protein and 20 grams of hydrolyzed collagen per serving, Bulletproof’s collagen formula is right up there Vital Proteins packing a big punch of collagen in each serving. The unflavored collagen is sourced from grass-fed and pasture-raised cattle, making it an abundant source of types I and III collagen.

If you prefer flavor, Chocolate and Vanilla options are available. Still, there’s a call-out worth noting: Unlike Bulletproof’s single-ingredient unflavored formula, each flavor contains MCT oil powder, coconut creamer, coconut oil, and several other ingredients. While the loftier ingredient list isn’t inherently “bad” per se, they bump up the overall calories, carb, and fat content and is something to consider.

Another consideration is that while Bulletproof is a popular brand, especially known for its keto coffee, there’s currently no confirmation regarding whether or not it’s third-party tested. Bulletproof does, however, claim to provide ethically sourced collagen at clinically effective doses. 

As we found in our own testing, you can easily incorporate Bulletproof’s collagen into coffee, smoothies, and other recipes such as baked goods and soups. “I even put it in a cup before my coffee one time, turned on the Keurig and then walked away and didn’t stir it,” says Kate Meier, GGR head of content. “When I came back, it had completely dissolved. I thought it would be clumped in the bottom, but it wasn’t. It mixes so well with no clumps.”

Oh, and Bulletproof products come with a 100% satisfaction guarantee, so if you’re not completely satisfied, you can get your money back or select a comparable product within 30 days. 

Best Collagen for Athletes: BUBS Naturals Collagen Protein

Best for Athletes

BUBS Naturals Collagen Protein Powder

GGR Score: 4.4

Check Price

Product Highlights

• Unflavored collagen peptide supplement made from bovine hide
• 20 g of collagen in each serving
• Gluten-free, soy-free, nut-free, GMO-free, and corn-free
• NSF-certified supplement
• Claims to support joint health, stronger hair and skin, digestive health, and assists in recovery
• Comes in 10- or 20-oz tub, or in travel packets
• Has more than 17 amino acids, including 7 essential amino acids

Pros & Cons

Pros

• Travel packets are convenient
• Mixes well
• Unflavored and doesn’t affect taste
• NSF-certified for sport
• Higher protein content for a collagen supplement

Cons

• Pricier for a collagen supplement
• Less than 30 servings per 20-oz container

Bottom Line

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).

When a product is NSF Certified for Sport, it means it has been third-party tested to ensure that the label of the product is accurate and that the product is free from prohibited substances, masking agents, and unsafe levels of contaminants. BUBS Naturals Collagen Protein is NSF Certified for Sport, so it has been cleared of the 270+ substances banned by the World Anti-Doping Agency (WADA). Therefore, athletes can consume it knowing it won’t contain elements that could damage their ability to compete.

We also like this protein for athletes because it has one ingredient: bovine hide collagen peptides. This type of collagen is easier to digest. On top of that, there are 17 amino acids present in this formula, seven of which are the essential amino acids necessary to repair and grow tissue (which athletes need).

BUBS uses Type I and Type III collagens, which work together to improve overall health and vitality. In each two-scoop serving, you get 20 grams of collagen.

GGR’s head of content and competitive weightlifting athlete Kate Meier has used BUBS Naturals Collagen Protein daily for a few months. She rated the product a 5 out of 5 for its unflavored taste, and a 4 out of 5 for how it mixes.

“It says it’s unflavored, and it truly is. I can’t taste it at all in my morning coffee,” she says. “This works pretty well dissolving in coffee—you can see some small pieces of it floating around, so I’d say it isn’t the best, but I can still drink it every day. In cold water, there is some sediment that settles to the bottom.”

Athletes like Kate tend to travel for meets, and she found the BUBS packets convenient.

“Also, BUBS has small travel packs that I took with me on a trip to D.C.,” she says. “I had no issues flying with them, and they are single-serving so you can take it on-the-go. Expensive? Yes. But super convenient.”

At north of $1.50 per serving depending on where you purchase it, this is one of the more expensive collagens on our list. However, athletes should expect to pay more for supplements that are NSF-certified.

Cons

• Does not dissolve easily

Bottom Line

If you are able and willing to pay a bit more for a clean and high-quality collagen with the added bonus of having probiotics and vitamin C, Ancient Nutrition’s Multi Collagen Protein Powder may be a good option for you.

Ancient Nutrition’s collagen might be our best budget-friendly pick, but trust us, it’s far from low-quality. It’s also the first on our list to provide collagen peptides from multiple sources and the only one offering diverse flavor options.

To kick off the uniqueness of the Ancient Nutrition Multi Collagen Protein, it provides all five collagen types (types I through V) sourced from grass-fed, pasture-raised beef, chicken, eggshell membrane, and wild-caught fish. The multi-collagen blend is intended to support healthy hair, skin, nails, and the gut. 

Each scoop also provides 2 billion CFUs of Bacillus coagulans³, a probiotic that may benefit the digestive and immune systems and ease rheumatoid arthritis symptoms. You’ll also get your daily vitamin C needs to support collagen production.

But back to those flavor options: Chocolate, Cold Brew, Cucumber Lime, Strawberry Lemonade, and Vanilla are all up for grabs. You can also opt for Unflavored and know that all are free of GMOs, dairy, gluten, and soy. GGR Editor Frieda Johnson tried the Unflavored version of this and said there is a slight taste to it if just mixed with water, but it blends fine into other drinks, like the best protein powder for smoothies.

• Fairly high dose of bovine collagen

Pros & Cons

Pros

• NSF Content Certified and NSF for Sport Certified
• Includes 5 mg of zinc and 1 mg copper
• Sourced from pasture-raised and pasture-finished cattle

Cons

• Some reviews claim it’s a bit clumpy
• Not everyone will want added zinc or copper

Bottom Line

The Pro Collagen from Gnarly Sports Nutrition, which aims to protect joint and connective tissues, is pasture-raised and pasture-finished and includes added vitamins and minerals like vitamin C, zinc, and copper.

If you’re looking for a collagen that provides 100% of your daily value of vitamin C, this is it.

It also supplies vitamin C (90 milligrams or 100% DV), zinc (15 milligrams or 136% DV), and copper (1 milligram or 111% DV) to assist with collagen strength, protection, and synthesis. 

NSF Content Certified and NSF for Sport Certified, Gnarly Collagen Pro is a great option for athletes and anyone, really, concerned about the contents of their collagen. Like all NSF Certified for Sport products, Gnarly Collagen is tested for 270+ substances banned by the World Anti-Doping Agency (WADA).

Gnarly Collagen Pro is intentionally unflavored to blend in pre-workout beverages without altering the flavor. It also comes in travel packs, with five and 10-stick options, so you can throw them in your gym bag and enjoy them on the go. GGR Senior Editor Nicole Davis tried this collagen and had good things to say about its solubility and taste, or lack thereof—she’ll definitely continue to incorporate this into her routine.

Product Highlights

• Combines both type I and III collagen 
• Added probiotics for gut health and digestion
• 8.5 g of MCTs from organic coconut
• Available in creamy vanilla and fair trade chocolate

Pros & Cons

Pros

• Mixes well
• Two types of collagen
• Solid profile of amino acids
• Taste is popular

Cons

• Reports of the desiccant packs bursting
• Includes stevia

Bottom Line

Combining grass-fed collagen types I and III with both probiotics and MCTs, the Garden of Life Collagen Creamer is formulated to improve the health of your gut, hair, skin, nails, and joints while also promoting energy.

While all collagen powders can be mixed into your morning cup of joe, the Garden of Life Collagen Creamer is designed to be a delicious, dairy-free creamer. It comes in Creamy Vanilla and Fair Trade Chocolate formulated with natural ingredients like natural vanilla flavors and organic stevia. With each scoop, you’ll get 9 grams of protein and 10 grams of collagen peptides sourced from bovine. One scoop serving also provides 500 million CFUs from Bacillus subtilis⁴, a type of probiotic that offers antimicrobial and digestive health benefits.

RELATED: Best Probiotic Supplements

GGR Senior Editor Nicole Davis gave this collagen product a 4.5 out of 5 on taste. She says the Vanilla flavor tastes like any vanilla creamer you’d buy, “Although the macros on this are not great—140 calories per serving—and it doesn’t provide nearly as much protein as other collagens on the list, the taste is great,” she says. “If you’re someone just starting out with collagen and who already uses creamer, this would be a good swap for a healthier option.” 

As a Keto-certified formula, it also provides MCT from organic coconut oil. MCTs are a unique type of fatty acids metabolized faster than other dietary fats. Research⁵ suggests that MCTs can help induce ketosis without the need for a traditional ketogenic diet or prolonged fasting while also being explored for weight control, brain health, and more. The collagen creamer is also certified paleo, non-GMO tested, and NSF certified gluten-free. 

We’d also be remiss not to mention the price per serving on this collagen creamer, which is very high comparatively. “It’s HELLA expensive,” Nicole says, “and the whole tub only has 12 servings, too, which means you’re out in less than 2 weeks if you use it daily.”

Cons

• Some users report canisters arrived with no safety seal
• Flavorless powder reportedly tastes bad

Bottom Line

Vital Protein’s Collagen Peptide Protein is formulated to improve the health of joints, bones, skin, ligaments, tendons, nails, and hair.

Vital Proteins is a leader in the world of collagen supplements. Its collagen peptides powder provides 18 grams of protein sourced from grass-fed and pasture-raised cows, making it a great source of types I and III collagen. 

We like it for its solubility, giving it a 4.5 out of 5 in this area. “The solubility isn’t as perfect, though,” says Amanda Capritto, GGR staff writer and certified sports nutrition coach. “When mixed with just water, there are some small chunks. I didn’t notice anything when mixed with other powders or coffee.”

The Vital Proteins collagen peptide formula also contains hyaluronic acid, an active ingredient in skincare topical creams, to help improve joint and skin health by improving hydration, according to a review published in Dermato-Endocrinology.⁶ The addition of vitamin C⁷, which is required for the biosynthesis of collagen, may synergize benefits for healthy skin, bones, cartilage, and the entire body.  

We rated Vital Proteins a 5 out of 5 for its formulation. The Unflavored and Flavored options—Chocolate, Lemon, and Vanilla—are free of added sugars, artificial flavors, dairy, and gluten. All varieties contain natural flavors and sweeteners like cocoa, sea salt, and stevia. Amanda mixes the unflavored Vital Proteins into many drinks and even oatmeal and has no problems with a weird taste.

Every Vital Proteins product is third-party tested by independent labs and manufactured in NSF-certified facilities. Vital Proteins’ “Vital Performance” line also features NSF Certified for Sport products.

Best Liquid Collagen Supplement: Momentous Collagen Shot

Momentous Collagen Shot

GGR Score: 3.9

Product Highlights

• Proprietary form of collagen 
• Designed to be taken without any liquid
• Orange-mango flavor
• Contains vitamin C

Pros & Cons

Pros

• Convenient
• No mixing required
• Added vitamin C
• Versatile

Cons

• Mango flavor is overwhelming to some
• Expensive

Bottom Line

Taking a unique twist on traditional collagen powder supplements, the Momentous Collagen Shot collagen comes as a ready-to-drink liquid that can easily be taken on the go.

While Momentous offers a powdered collagen option, its unique collagen shot is the first on the market and deserves its own showcase. The Momentous Collagen Shot is a convenient, ready-to-drink pouch created to fit seamlessly into any lifestyle. 

The Momentous Collagen Shot provides 10 grams of hydrolyzed collagen and protein sourced from bovine hide and bones, making it a great source of types I and III collagen. It also contains 35 milligrams of vitamin C to promote natural collagen synthesis and enhance its benefits. 

The collagen shots are gluten-free, non-GMO, and third-party certified through Informed Choice and Sport. The only minor downside is it only comes in one Orange Mango flavor, although product reviewers exclaim it “tastes great” and is “so yummy!”

Our own tester, GGR Staff Writer Lauren Strong, said the taste is interesting. “It’s not great, but it also leaves you feeling curious about it all at the same time,” she explains. “It’s fruity and you can pick up on the orange pretty easily, however there is this chalky aftertaste that is really weird and it kind of takes over your mouth unless you just suck down the entire gel packet at once.”

Despite this, Lauren says she’d rather take this liquid/gel format over powder any time. She likened the texture to a running gel, like Gu.

“The gel is a little weird if you’re not used to energy gels or the like, which I’m not,” she explains, giving the texture a 5 out of 5. “However, it’s easy to get down and it’s blended really well and it super consistent throughout the whole gel packet.”

GGR Score: 3.8

Check Price

Product Highlights

• Bioavailable collagen peptide blend
• Unflavored powder 
• Non-GMO and gluten-free 
• No added sugar, sweeteners, or preservatives
• Collagen peptides derived from fish (tilapia)

Pros & Cons

Pros

• Multiple reports of decreased joint pain
• Non-GMO
• No added sweetener, flavors, or preservatives
• Affordable

Cons

• Taste is not for everyone
• Hard to mix with cold liquid

Bottom Line

The Marine Collagen Peptides’ supplement is a budget-friendly collagen supplement containing 5 grams of collagen peptides derived from marine sources.

While most collagen supplements are sourced from bovine, Procaps solely provides marine collagen peptides derived from tilapia fish. Whereas anyone is welcome to enjoy marine collagen, it’s especially great for those following a pescatarian diet—a mostly plant-based diet that includes fish but often not other animal sources.

As our first marine-based collagen, it’s important to note it mainly contains types I and II collagen instead of the more common types I and III sourced from bovine. Also, recall that type II collagen is primarily found in cartilage and may be most beneficial for joint health.¹

The marine collagen powder is flavor-neutral and mixes easily in any liquid. However, the official website suggests it dissolves best if the liquid isn’t cold unless combined with a blender like into a smoothie. GGR Head of Content Kate Meier agrees with the flavor neutral sentiment, saying it’s a very decent collagen that she couldn’t detect when mixed into her morning coffee. She gave it a 3 out of 5 for taste, noting that alone, the product just “tastes like collagen.”

The collagen is also manufactured in the same lab that distributes it, insinuating it’s not independently tested. While this does not necessarily mean it’s a contaminated and impure product, no obvious sign tells us it’s rigorously tested.

Product Highlights

• Collagen peptides in pill form
• Each serving contains 2,500 mg of collagen peptides
• Brand claims it's formulated to increase bioavailability
• Quality and efficacy stated to be scientifically verified

Pros & Cons

Pros

• Convenient
• Cost is affordable
• Reported verification of quality and effectiveness
• Formulated based on clinical studies

Cons

• Few reports of weight gain
• Pill form is less versatile

Bottom Line

If you prefer to take a daily pill over mixing a collagen powder to reap the benefits of a collagen supplement, the Trunature Healthy Verisol Collagen is an affordable and convenient choice.

While most collagens come in powdered form, there are some much-needed exceptions. TruNature Healthy Skin Verisol Collagen is one of them. Besides, some people just prefer to pop in a tidy capsule or a few and be done with it. GGR Staff Writer Lauren Strong tried these, and found the pill form to be much easier than powder for her. 

Four capsules (a serving) of the TruNature collagen capsules provide 2,500 milligrams (or 2.5 grams) of Healthy Skin Verisol® Bioactive Collagen Peptides. Oh, and two grams of protein. 

With some digging, Vital Proteins tells us that Verisol® is a patented collagen peptide sourced from grass-fed and pasture-raised bovine. And the major difference between collagen peptides and Verisol® collagen is that the latter works best with a concentrated 2.5-gram dose, which TruNature provides. (If you prefer gummies, Vital Proteins also offers 2.5-gram quantities of Verisol®.)

A 2013 research study⁸ randomized 114 women to receive 2.5 grams of Verisol® or a placebo once daily for eight weeks. The researchers found that taking Verisol® can reduce eye wrinkles while significantly increasing procollagen type I and elastin⁹, a protein that provides elasticity and resilience to tissues and organs like the skin—it’s roughly 1,000 times more flexible than collagens!

Cons

Bottom Line

For those who don’t want to bother with mixing powdered supplements, HUM Collagen Love capsules is a high-quality alternative.

HUM Nutrition Collagen Love is formulated with verified “clean” ingredients, including types I and III collagen sourced from grass-fed, pasture-raised beef. It also provides vitamin C and hyaluronic acid, which may enhance the absorption and benefits of collagen related to skin, joint, and bone health, all in an easy capsule form, which GGR Staff Writer Lauren Strong said was easy to get down. 

HUM’s collagen capsules also bring a few new ingredients to the collagen table: chondroitin sulfate and a combo of red wine and grape seed extract. As a critical compound in skin structure, chondroitin sulfate¹⁰ is involved in many biological functions—like inflammation, infection, and wound repair—and may even improve osteoarthritis symptoms. 

Rich in polyphenols and proanthocyanidins, the red wine and grape seed extracts¹¹ help protect the body from oxidative stress and subsequent health issues like high cholesterol and metabolic syndrome.

All HUM products are formulated by RD Nutritionists, which I can truly appreciate as a fellow dietitian, and triple-tested and third-party validated for purity and quality. They’re also free of the “Tricky 12”—a set of 12 ingredients HUM avoids in supplements—that includes artificial colors, sweeteners, flavors, and preservatives.

Primal Kitchen Collagen Fuel is made without dairy, whey, or soy and is formulated to improve the health of your hair, skin, and nails.

In the market for flavorful collagen peptides while following a low-carb or keto diet? Primal Kitchen Collagen Fuel might just be up your alley! 

The keto-friendly collagen contains 11 grams of collagen and protein sourced from cattle ranches in South America. It’s important to note that Primal Kitchen removed the grass-fed claim in 2018, although they assure that the collagen meets high-quality standards and undergoes rigorous testing to meet regulatory guidelines.

Aside from the collagen, it contains coconut milk powder that bumps up the fat content. Coconut milk powder¹² offers antioxidant properties and may lower inflammation and the risk of chronic diseases like high blood pressure and type 2 diabetes. 

Pick from three keto-certified flavor options—including Chocolate, Peanut Butter, and Vanilla—enhanced with more natural flavors like monk fruit, vanilla extract, and sea salt. All flavors are free of added sugar, dairy, whey, soy, and gluten. 

GGR Senior Staff Writer Amanda Capritto tried the Vanilla Coconut, which she said tastes fine, and mixed into water it’s slightly grainy but inoffensive. “There is a layer of foaminess on top, which kind of makes it look like a shaken cocktail. Unfortunately it doesn’t taste like a shaken cocktail. All things considered, it isn’t bad at all, but it could be less grainy.” You could mix this with the best keto protein powder for a nice low-carb drink as well.

Best Flavored Collagen Supplement: Vital Proteins Chocolate Collagen Powder

Best Flavored

Vital Proteins Chocolate Collagen Powder

GGR Score: 4.3

Check Price

Product Highlights

• Grass-fed, pasture-raised collagen 
• Alkalized cocoa powder and stevia for taste
• Made without sugar, gluten, soy, or dairy

Pros & Cons

Pros

• Taste is popular
• Mixes well with hot liquid
• Paleo and keto friendly
• Reportedly very effective in improving skin, nail, and hair health

Cons

• Contains stevia which some users felt left an aftertaste
• Questionable quality assurance through Amazon

Bottom Line

If you're looking for a collagen supplement with a solid dose of high-quality collagen and a bit of flavor, Vital Proteins Chocolate Collagen Powder may be for you.

Vital Proteins is at it again, with the best flavored Chocolate collagen protein. We also like how it’s formulated with more natural ingredients—like alkalized cocoa, sea salt, and stevia leaf.

But the prominent feature of the Vital Proteins Chocolate formula is its bovine collagen peptides. And like all Vital Proteins collagen products, its chocolatey option is sourced from grass-fed bovine that’s rich in types I and III collagens.

The primary difference between the Unflavored and Chocolate options is the Nutrition Facts. The Unflavored only provides protein and collagen, but the Chocolate contains 4 grams of total carbohydrates and 2 grams of dietary fiber.

GGR Senior Staff Writer Amanda Capritto has tried both the Unflavored and Chocolate versions, and said she’d choose Chocolate over Unflavored if she had to mix it with water. “Mixed with a vanilla or chocolate protein powder or in a smoothie, it basically just adds a cocoa flavor and otherwise goes unnoticed,” she explains.

The Chocolate flavor also comes in an NSF Certified for Sport option under the “Vital Performance” product line.

Other Collagen Supplements We Researched and Tested

As collagen grows in popularity, countless products are on the market. In addition to our top picks, we also researched and tested these collagen supplements: 

• Garden of Life Collagen Peptides: We found that this one had a slight taste, and the smell was very off-putting. 
• Great Lakes Daily Marine Collagen Peptides: Although the flavor of the Raspberry Lemonade was good, this powder was not very soluble, so we left it off the list. 
• Nordic Naturals Marine Collagen Powder: This one had huge issues with solubility.
• Orgain Grass Fed Pasture Raised Collagen Peptides: Seems like a great product, but we haven’t tested this one yet.
• Vital Proteins Beauty Collagen: We’re fans of the Vital Proteins brand, but we just haven’t tested this product yet so we left it off the list.
• Further Food Collagen Peptides: Another unflavored option, this collagen from Further Food provides less collagen per serving than the one from Swolverine. However, we still think it’s a solid option.

How We Picked and Tested the Best Collagen Supplements

When rounding up the best collagen powders on the market, this is what we looked out for:

Benefits of Collagen Supplements

Can collagen supplements really support your health and wellness?now Let’s see what the latest research shows: 

• May help sustain collagen in the body: Collagen loss in the body can start as young as 18 years with an estimated 1% decline per year after age 40.¹ Other factors can impact collagen production—like nutritional deficiencies, smoking, and stress—and supplementing with collagen may protect from such dramatic losses. 
• May counter skin aging: A 2021 meta-analysis¹³, that included 19 studies and over 1,000 participants aged 20-70 years, suggests hydrolyzed collagen can improve skin elasticity, hydration, and wrinkles.
• May alleviate joint pain and stiffness: Collagen supplements for joints may alleviate osteoarthritis¹⁴ symptoms such as joint stiffness. And according to a 2021 meta-analysis published in Amino Acids¹⁵, collagen peptide supplementation is most beneficial in improving joint functionality and reducing joint pain.
• May improve digestive symptoms: While the data between collagen and gut health is limited, a 2022 study¹⁶ hints that 20 grams of daily collagen peptide supplement may reduce bloating and improve mild digestive symptoms in otherwise healthy women. 

A 2021 review¹⁷ exploring the effects of collagen in clinical studies further suggests supplementation may support bone and dental health, manage acid reflux, and promote wound healing. 

Dosing and Interactions 

Currently, there are no uniform and official guidelines about how much collagen to take each day. However, some evidence¹⁸ shows that taking 2.5 to 15 grams of collagen peptides appears safe and effective without the risks of interactions and side effects, with newer evidence showing benefits with 20 grams of collagen daily.¹⁰ 

Before taking any dietary supplement, we encourage you to seek guidance from a registered dietitian nutritionist (RDN) or another healthcare professional. They can help you determine if a collagen supplement is right for you and which product best aligns with your health needs and goals. 

Third-Party Testing

Third-party testing is when a company sends its product to an independent lab to evaluate its quality and safety. A visible stamp on the product’s packaging tells you if it’s been third-party certified, and the following are ones we commonly trust and look out for:

• Informed Choice 
• NSF 
• Banned Substances Control Group
• US Pharmacopeia (USP) Verification 

Products can also be certified to help consumers make well-informed decisions related to specific dietary restrictions and preferences, including:

• Gluten-free
• Halal
• Kosher
• Non-GMO
• Organic
• Vegan

If you stumble upon a product and can’t tell if it’s third-party tested, you could always contact the company for more information.

Buying Guide: What to Look for in Collagen Supplements

Ready to see what collagen could do for you? When looking for the best collagen supplement for you, ensure it matches and checks all of these boxes:  

• Type of collagen: Because the different kinds of collagen come with their own uses and benefits, consider your personal health goals and match the type accordingly. For instance, types I and III are mostly used to support nail, skin, and hair health while type II mostly benefits the joints and bones. 
• High-quality collagen formulas: Ensure the collagen is formulated with high-quality sources, including grass-fed bovine and wild-caught fish. Also, try to go for collagen, especially if flavored, formulated with natural ingredients and free of artificial ingredients and other unwanted additives. 
• Intake form and flavor: The utmost importance is finding a form and flavor that you enjoy most and will take consistently to reap the benefits. 
• Certifications: Check to see if the collagen is third-party tested as mentioned right above (like through NSF). Also, look for products with certifications that align with your dietary restrictions and preferences, such as being gluten-free or vegan.
• Brand reputation: Is the brand reputable with clear values and a positive track record? This is helpful to know before purchasing a product and supporting the company.
