You’re going HAM in the gym, eating your carbs and protein, drinking your H20, getting enough sleep, and even taking your favorite pre-workout before you get down and dirty—what else could possibly give you an edge to increase strength and charge up your results? 

Let’s welcome creatine to the chat.

Creatine is an amino acid (derived from arginine) that’s found in both animal proteins and within our own muscle cells. It’s used by the body to replenish ATP (adenosine triphosphate) stores, which is the energy source your body uses for explosive movements, like sprinting and heavy lifting, according to a manuscript in the journal International Immunopharmacology1, which also emphasizes the many other benefits of creatine.

Creatine supplementation has been researched fairly extensively, and has been shown to boost the effects of short-duration, high-intensity exercise on muscle strength and size2. Read on for information about why creatine is an effective supplement, what you should consider when choosing a creatine product, and our list of the best creatine supplements to buy.

Good for: A trainee whose main goal is to increase muscle size 

Best Creatine for Muscle Growth

Transparent Labs Creatine HMB

GGR Score: 4.85 starstarstarstarstar

Product Highlights

  • Uses research-backed doses 
  • Available in 10 fruit flavors as well as an unflavored option
  • Free from artificial sweeteners, colored dyes, fillers, and harmful additives

Pros & Cons


  • 10 flavors, 1 unflavored option
  • Includes B-Hydroxy B-Methylbutyrate (HMB)
  • 5 grams of creatine monohydrate per serving
  • Contains no added sugar, artificial sweeteners, dyes, or fillers


  • No stimulant (for those looking for pre-workout boost)

Bottom Line

Transparent Labs’ Creatine HMB puts a unique twist on the more traditional creatine monohydrate by adding HMB to more effectively build strength, stamina and recovery.

If you’re looking for creatine to support muscle gain—or the best creatine for bulking—Transparent Labs Creatine HMB is a good choice. It puts a twist on a traditional creatine supplement. Each serving contains the recommended 5 grams of creatine monohydrate, which has repeatedly been shown to increase power3, repeated sprinting ability4, maximal strength5, and muscle mass6.

This product also contains 1.5 grams of beta-hydroxy beta-methylbutyrate (HMB) per serving. 

“HMB is a metabolite of the amino acid leucine, which helps to prevent the breakdown of muscle protein and can help speed up the recovery process from strenuous exercise,” explains Dr. Kendall. *

It also contains BioPerine, a patented form of piperine, which has been shown to increase the absorption rate of numerous compounds it is taken with7, which in this particular case are creatine and HMB. *

There are 10 flavors of Creatine HMB available—Sour Grape, Peach Mango, Fruit Punch, Watermelon, Black Cherry, Blue Raspberry, Orange, Tropical Punch, Hawaiian Splash, and Strawberry Lemonade—plus an unflavored option if you just want to stick to the basics. Know, too, that there are no artificial sweeteners, colors, or preservatives in any flavor of this supplement either.

Nicole, GGR editor and our expert product tester, says:

“I tried Black Cherry and I wasn’t a huge fan of the taste of this one—it tasted a bit watered down, even with the right amount of water. Some people may prefer this though! There were floaties after I finished mixing, but it didn’t interfere with the overall drinking of it.”

Product Highlights

  • Only patented form of creatine HCL
  • Kaged Creatine HCl skips the loading phase
  • Available in capsule form as well
  • Third-party tested
  • Available as Unflavored or Lemon Lime
  • Free from artificial flavors and colors
  • Formulated to avoid gastrointestinal issues

  • Expensive

Bottom Line

If you're looking for a pure creatine HCL and are willing to pay for high quality, Kaged Creatine HCl may be for you.

Whereas most creatine supplements use creatine monohydrate—the most researched form of creatine—Kaged Creatine HCl uses a patented form of creatine hydrochloride (HCL) which may aid in faster absorption rates and reduced bloating8. *

According to Dr. Kendall, benefits of HCL include that it’s super soluble and easy to mix in any liquid, it doesn’t require a loading phase, and can help you combat gastrointestinal disturbances, like occasional gas, cramping, and bloating, and temporary weight gain from water retention, which may occur with creatine use. This is great for those who are concerned with weight loss and muscle preservation. We could call this product “best creatine for bodybuilders,” too, just for that reason. *

It’s available in powder form in unflavored and Lemon Lime, as well as a capsule form. And although it only costs $.40 per serving, the instructions recommend you take 4 servings per day—this means one container wouldn’t even last you three weeks. 

Each batch is also certified by Informed Sport, meaning it’s tested for banned substances (on the WADA banned list).

Nicole, GGR editor and our expert product tester, says:

“It completely dissolved, so for solubility it gets an A+. I tried the Lemon Lime flavor and really liked it—it was tart and not too sweet.”

Bottom Line

If you’re looking to add some bulk with pure creatine, Optimum Nutrition Micronized Creatine Monohydrate is one worth considering.

Optimum Nutrition Micronized Creatine Monohydrate has everything Dr. Kendall looks for in a creatine supplement. The only ingredient is 100% pure creatine monohydrate, which is the most researched form of creatine with over 500 peer-reviewed publications evaluating the potential benefits of the supplement.

With 5 grams of creatine per serving—the research-backed daily dose to see improvements in muscular strength, speed, power, and recovery according to Dr. Kendall—the sub-40 cent per serving cost is very reasonable. * Plus, it’s micronized creatine powder, which means the molecules have been cut down to improve solubility. 

And lastly, Optimum Nutrition’s Micronized Creatine Monohydrate has been tested in accordance with the Informed Choice certification, which means there are no banned substances on the WADA banned list snuck inside.

Best Creatine Capsules: Optimum Nutrition Capsules 

Good for: Someone who’d rather swallow a creatine pill 

Best Creatine Capsules

Optimum Nutrition Micronized Creatine Capsules

GGR Score: 4.5 starstarstarstarstar

Product Highlights

  • Supports muscle growth, recovery, and overall performance
  • Provides 2.5 grams of creatine monohydrate per 2-capsule serving (5 grams recommended daily)
  • Easy to take on the go
  • Should be taken with a meal
  • Receives great reviews for its effectiveness

Pros & Cons


  • Capsule form is more convenient for some
  • No need to worry about mixability or taste
  • Main ingredient is high-quality creatine monohydrate
  • Fewer reported digestive side effects


  • Must take four pills for 5-gram dose
  • More expensive than powder form

Bottom Line

If you prefer capsules over powder, the Optimum Nutrition Micronized Creatine Capsules provide the same dosage and affect on performance as seen in the traditional powder supplement.

If mixing creatine powder in a liquid doesn’t sound appealing to you, don’t fret—there are quite a few creatine capsules available on the market. We like Optimum Nutrition’s because the brand is widely respected and the reviews are overwhelmingly positive. 

An image of Optimum Nutrition creatine capsules in a woman's hand

Creatine in capsule form tends to be much easier to transport, if you want to take your supps on the go with you during the day, and you don’t have to worry about mixing or measuring. Plus, you won’t have to deal with any flavors (or aftertaste) you don’t like. 

One downside of these capsules is that you’ll have to take four to hit the recommended 5-gram dose, which takes the price per serving up to 90 cents. If taking pills is no issue for you, then this shouldn’t be a problem; if it is, you may want to think twice. 

Nicole, GGR editor and our expert product tester, says:

“These are pretty big pills, but if you don’t mind that, capsule form would be easy!”

You’ll also find 2 grams of L-carnitine L-tartrate per serving of Growth Surge, which can help fight muscle soreness post-exercise. *

This post-workout supplement is available in eight flavors—Cherry Limeade, Blue Raspberry, Fruit Punch, Blueberry Lemonade, Swoleberry, Watermelon, Black Cherry, and Unflavored—and costs $1.33 per serving. Just keep in mind, you’ll only be getting 3 grams of creatine in one serving, so you may need to consider more supplementation to follow recommendations on dosage for maximal benefits. 

Nicole, GGR editor and our expert product tester, says:

“The solubility of this one isn’t great, but I tried Cherry Limeade and liked the flavor. I though there was a slight aftertaste, though—not horrible, but super noticeable.”

It contains creatine—and only creatine—plus a micronized form at that, which means it’s easily soluble. It’s also free of added sugar, soy, dairy, gluten, or any other additives. 

This product is also third-party tested to ensure that there are no banned substances inside. 

At 70 cents per serving, it’s not the cheapest option on our list, but reviewers rave about the solubility and great customer service, so we’re calling that a win.

Nicole, GGR editor and our expert product tester, says:

“This powder dissolved completely and is unflavored—both checkmarks in my book. One downside though: There’s no scoop with this product, so you’ll have to measure out your servings with your own measuring spoons.”

We all know protein powders are the go-to post-workout drink, but we like Legion Recharge as a post-workout drink because you’re getting a few research-backed ingredients that will help with muscle recovery and repair.

An image of Legion Recharge post-workout drink with creatine in a shaker

Beyond the 5-gram dose of micronized creatine, you’re also getting 2.1 grams of L-carnitine L-tartrate, which Dr. Kendall says has been shown to combat muscle soreness and improve muscle repair. *

Additionally, 10.5 milligrams of corosolic acid is there to enhance post-workout nutrient absorption. *

Available in four flavors—Blue Raspberry, Fruit Punch, Grape, and Strawberry Lemonade—Recharge has zero added sugar and no artificial food dyes or fillers, plus it’s naturally sweetened with Stevia. It’s also third-party tested so you know exactly what you’re getting.

Nicole, GGR editor and our expert product tester, says:

“The Strawberry Lemonade flavor was pretty sweet but also a bit tart, so it balanced out in my eyes. Recharge also gets an A for solubility.”

Good for: Someone who wants to get their creatine in with their pre-workout

Best Creatine Pre-Workout

Kaged Pre-Kaged Elite

GGR Score: 4.72 starstarstarstarstar

Product Highlights

  • Pre-workout formulated with creatine monohydrate and creatine nitrate
  • 5 grams of total creatine
  • Expensive—$3 per serving
  • Third-party tested
  • 3 flavors: Strawberry Lemonade, Fruit Punch, Glacier Grape

Pros & Cons


  • Pre-workout and creatine in one
  • Contains 5 grams of total creatine
  • Third-party tested


  • Expensive

Bottom Line

If you're looking for a product that combines a pre-workout with creatine, Kaged Pre-Kaged Elite might be a good choice.

We named Kaged Pre-Kaged as the best pre-workout supplement because of its research-backed doses of ingredients shown to boost energy and performance, plus full transparency on the label. Its brother, Pre-Kaged Elite, is an all-in-one pre-workout that contains nine patented ingredients, including two forms of creatine—monohydrate and nitrate. 

The 5 grams of total creatine hit the right mark for daily dosing to support strength and increase muscle mass, plus Dr. Kendall likes the addition of 10 grams of L-citrulline, a compound shown to promote increased blood flow and nutrient delivery to active muscles10, plus 3.2 grams of beta-alanine, which is the recommended daily dose to reduce muscle fatigue, increase endurance, and performance during high-intensity exercise11. *

All in all, this third-party tested pre-workout is designed to deliver more energy, bigger pumps, greater power, and support sharper focus. And, at a whopping $3 per serving, it better provide hella benefits. But, considering it rolls two supplements (creatine and pre-workout) into one drink, it could be cost-effective for the right person.

Nicole, GGR editor and our expert product tester, didn’t get to try this one yet, but she has tested Kaged Pre-Kaged. It wasn’t too sweet and she liked the flavor, but did have some concerns about solubility.

Other Creatine Powder We Tried and Researched 

Creapure Creatine: This is a type of branded creatine monohydrate produced in Germany and distributed by a handful of partners including Proteinfactory and BPN. It is touted to be high-quality, but there seemingly isn’t anything special about this product versus another micronized creatine monohydrate. 

Beast Sports Creature Creatine: This product contains a blend of five types of creatine, totaling only 4 grams—less than the ideal 5-gram serving size. Plus, creatine monohydrate is the most studied type of creatine with the most proven benefits, so we opted for products mostly containing just that.

Cellucor Cor-Performance Creatine Monohydrate: Another micronized creatine monohydrate powder at an affordable price point of less than 50 cents per serving. We’d call this a solid runner-up for sure. (We also love Cellucor’s C4 pre-workout, and even have a special coupon code for GGR readers.)

How We Picked and Tested the Best Creatine

We narrowed down our list of the top nine creatine products by weighing the following factors:

  • Formulation: Does the product contain strictly creatine, and how much? If there are other ingredients present, are they research-backed and included with a purpose?
  • Serving size: The ideal dosage of creatine is 3 to 5 grams per day12—how many servings do you need to hit this?
  • Solubility: If powdered, does the product dissolve completely in liquid? 
  • Cost: What’s the price per serving?
  • Third-party testing: Has the product been tested for banned substances by Informed Sport, NSF, or Banned Substance Control Group (BSCG)?
  • Taste/Flavors: Is there more than an unflavored option? How do all of them taste?

What is Creatine?

Dr. Kendall is breaking it all the way down for us. Here are some of the key facts:

  • Creatine is a naturally occurring amino acid that’s found in animal proteins like meat and fish, and is also made by the human body in the liver, kidneys, and pancreas.
  • Approximately 95% of your body’s creatine is stored within your muscles, with the other 5% is stored in your brain tissue. 
  • Creatine is used by the body to replenish ATP (adenosine triphosphate) stores, which is the energy source your body uses for muscular contractions and explosive movements, such as sprinting and heavy lifting.

What Are the Different Types of Creatine?

Creatine monohydrate is the most studied and most popular form of creatine used in supplements, but it’s not the only form available on the market. Three other popular variations include creatine hydrochloride (HCL); Kre-Alkalyn, which is creatine buffered with bicarbonate; and creatine nitrate (creatine bound to a nitrate molecule).

Creatine monohydrate is the least expensive form of creatine and the one most commonly used in research studies—so you know it works.

Creatine HCL is a creatine molecule bound to hydrochloric acid to enhance its solubility and overall absorption rates. Because of this, Dr. Kendall explains, you may be able to take a smaller dose (1 to 2 grams) and still observe the same benefits as taking 5 grams of creatine monohydrate. Consuming less product may help curb bloating and other minor gastrointestinal symptoms you may experience when taking larger doses of creatine monohydrate. *

Then there’s Kre-Alkalyn. “Manufacturers of Kre-Alkalyn claim that the addition of an alkaline powder (like bicarbonate) reduces the breakdown of creatine in the stomach leading to improved creatine uptake in the muscle,” says Dr. Kendall. “Improved absorption rates may mean you can skip the loading phase and still get the gains.”  

And lastly, similar to the other forms of creatine, creatine nitrate is thought to have greater solubility, meaning you may receive equal benefits from a smaller dose of creatine nitrate (3 grams) compared to creatine monohydrate.

There are other creatine formulas—including creatine magnesium chelate, creatine ethyl ester, creatine citrate, and liquid creatine—but they’re not nearly as popular and research surrounding their effects is limited.

Why Should You Take Creatine?

Creatine monohydrate is one of the most widely studied nutritional supplements, which is great news for you—this means that there’s research-backed evidence around the effects of creatine on performance and strength during high-intensity exercise.  

When you participate in short bouts of intense exercise—like a 10-second sprint or a one-rep-max squat—your body uses its anaerobic system and stores of adenosine triphosphate (ATP) for energy. ATP, which is produced by phosphocreatine stores inside your muscles, is limited. So, the idea is that if your creatine stores are not full, you may be missing out on potential ATP production, or in other words—leaving some untapped strength and power on the table. 

“While your body makes around 1 to 2 grams of creatine per day, individuals who train regularly may need to consume 5 to 10 g of creatine daily to maintain creatine stores,” says Dr. Kendall. “Creatine supplementation appears to be most useful for short-duration, high-intensity, intermittent exercise, and has been shown to boost the effects of resistance training on muscle strength and size, as well as athletic performance overall.”

Supplementing with creatine orally can help increase your intramuscular stores of creatine and phosphocreatine by as much as 40%,as shown in several studies13. Studies have also analyzed creatine monohydrate supplementation’s effect on strength and performance in resistance training exercises like leg press and bench press14, as well as explosive movements like jump height15, and a great majority have found improved results from the creatine supplementation group versus the control group. 

In fact, a meta-analysis16 of 22 studies found that the average increase in muscle strength following creatine supplementation was 8 percent greater than with just resistance training alone. Also, the increase in weightlifting performance was 14 percent greater than with just training alone.

How to Dose Creatine

According to Dr. Kendall, to maximize the benefits of creatine, you need to saturate your body’s stores of creatine, and there are two ways to do this:

  • Loading protocol: Creatine loading involves taking 20 grams of creatine a day, typically divided into four equal doses of 5 grams, for five to seven days. This has been shown to be an effective method to fully saturate your muscle’s creatine stores in one week’s time. Following the loading phase, it’s recommended to drop down to 5 grams of creatine daily to maintain creatine stores. 
  • Low-dose protocol: The alternative method is to simply take 5 grams of creatine every day, without a loading phase. This approach will eventually get your muscle’s creatine stores maximally saturated, it just takes a bit longer—about four weeks compared to one week with a loading protocol. 

Both the loading protocol and the low-dose maintenance protocol have been shown to produce significant improvements in muscle strength and size when used alongside a resistance training program

Potential Side Effects of Creatine

Studies examining the effects of long-term creatine supplementation have demonstrated no negative effects on liver, kidney, blood, bone, brain, or muscle function. More so, there is no data that shows creatine causes muscle cramps or leads to dehydration. On the contrary, according to Dr. Kendall, creatine supplementation has been proposed to increase total body water, which can help to maintain hydration status. 

However, taking creatine, especially larger doses, may cause some occasional, minor gastrointestinal issues. 

“It’s estimated around 5 to 7% of people who take creatine may experience stomach aches; however, taking smaller doses (3-5 grams) or using a micronized form of creatine may help reduce gastrointestinal distress,” Dr. Kendall says. “Creatine loading may also lead to an initial weight gain of 1 to 2% body mass in the first few days due to water being pulled into the muscle; however, this is less likely to occur if following a low-dose protocol.” 

Also of note: Although creatine doesn’t appear to affect kidney function in healthy individuals, it’s recommended that people with pre-existing kidney problems avoid taking creatine. Additionally, people with liver disease or high blood pressure should talk to their doctor first before taking creatine as there may be possible interactions with medications they are currently prescribed.  

How to Choose the Best Creatine for You

Before you whip out your credit card, decide what creatine supplement is the best fit for you. 

Decide What Your Goals Are

Are you strictly concerned with getting stronger? Are you concerned about muscle-building while staying lean? Creatine monohydrate is the most-researched type of creatine, but is known to have some minor side effects like gastrointestinal issues and water retention. Creatine HCL has less of this reported. Also creatine with HMB has been shown to help prevent the breakdown of muscle protein.

Consider Dosage

If you’re in a loading protocol and need to take 20 grams of creatine per day, consider the serving size of the supplement. Some containers only come with 30 servings, and if you need to take four per day, you’ll run through it quickly.  

And Also Cost Per Serving

Whether you purchase from Amazon or directly from the manufacturer, creatine can range from less than 40 cents per serving on the low end, to $3 per serving on the high end. The most affordable options are usually just creatine monohydrate with nothing else, while the more expensive options tend to have other ingredients in them, such as pre-workout or HMB. After deciding on your goals, you can come to the determination if extras are needed.

Pill or Powder?

Would you rather swallow a few pills to hit your creatine dosing, or does powder sound more appealing? Plenty of unflavored powders are available—you can mix them with almost any drink—or you can find flavored options as well. 

Choose Third Party-Tested Products

This is especially important if you’re an athlete, but really anyone taking supplements should heed this advice. Look for Informed Sport, NSF, or BSCG logos on the products to ensure they’ve been batch-tested for banned substances.

Is it OK to take creatine everyday?

According to sports nutrition expert Dr. Krissy Kendall, yes, it’s OK to take creatine daily. 

“When it comes to creatine, consistency is key,” she says. “Not only is creatine safe to take everyday, it’s the recommended approach to maximize the benefits of creatine. Unlike some supplements (i.e. caffeine), your body does not build up a tolerance to creatine, therefore cycling on and off serves no real purpose. Should you decide to stop taking creatine, it takes approximately six weeks for creatine stores to return back to pre-supplementation values. You may notice a decrease in energy and exercise intensity, however it will be no worse than where you were before you started supplementing with creatine.”
