The first time I added creatine to my post-workout shake, I expected nothing. Two weeks later, I was pushing harder on leg day and feeling recovered faster by Thursday. That’s when I started paying attention.
Creatine is one of the most researched supplements out there. It helps your muscles produce ATP — the compound that fuels every rep, sprint, and hard push you do. The science is clear. The options are not.
There are powders, pills, gummies, flavored and unflavored, micronized and not. Our expert product testers tried dozens of creatine supplements. We spoke with certified trainers and registered dietitians to narrow it down. Below are the seven picks that made the cut — any person can use them, though we framed this list for men.
All numbers below come directly from the source testing data.
Best Creatine Monohydrate: Transparent Labs Creatine HMB
Rating: 4.5/5 · Price per serving: $1.67 (30 servings) · Creatine per serving: 5 g
This one contains creatine monohydrate plus HMB, a compound your body naturally produces when it breaks down the amino acid leucine. Some research suggests HMB promotes muscle growth, though our R.D. reviewer Anna Marie Clear notes that “HMB has no greater effect than leucine alone.”
It also includes BioPerine — a black pepper extract that may help with nutrient absorption. The supplement earned 5 out of 5 stars for formulation and 4 out of 5 for taste.
There are 13 flavor options, the most on our list. Tester Pete Nastasi, C.P.T., tried Blue Raspberry and Strawberry Lemonade: “Both tasted great.” Other testers found a slight bitterness from BioPerine that didn’t bother them but was noticeable.
No added sugar, no artificial sweeteners or dyes. Informed Choice certified, gluten-free, non-GMO. A subscribe-and-save option is available.
It’s pricier than most options here. And it contains no stimulants, so don’t expect a pre-workout energy kick from this one alone.
Best Creatine for Athletes: Sports Research Creatine Monohydrate
Rating: 4.9/5 · Price per serving: $0.28 (100 servings) · Creatine per serving: 5 g
This is a single-ingredient formula: micronized creatine monohydrate. That’s it.
We rated the formulation 5 out of 5 because 5 grams per serving is the dose research shows optimizes muscle gain and athletic performance. It’s Informed Sport Certified — third-party tested for purity and banned substances — so if you compete, this one checks that box.
The micronized form dissolves easily. Our tester reported: “If you didn’t tell me there was creatine in this water I wouldn’t know.” She gave it 5 stars for solubility.
That said, the research doesn’t show micronized creatine is more bioavailable than standard monohydrate — it’s partly a marketing move. The real advantage here is mixability and price.
Unflavored only, powder only. Non-GMO and gluten-free. Subscribe-and-save available.
Best Creatine Gummies: Swoly Creatine Mono Gummies
Rating: 4.3/5 · Price per serving: $1 (30 servings) · Creatine per serving: 4 g
If you hate measuring powder or carrying a shaker bottle, these are worth trying. They come in one flavor — Strawberry — and our tester gave them 5 out of 5 for taste: “Dangerously delicious.”
One serving is five gummies with 4 grams of creatine monohydrate. That’s slightly below the preferred 5-gram dose. Clear notes that larger individuals may need more — “0.1 grams of creatine per kilogram of body weight” is the research-backed target.
Each serving has 15 calories and 2.5 grams of added sugar from sucrose, dextrose, and maltodextrin. Taking extra gummies beyond five could lead to GI symptoms from the sugar and gums. Formulation scored 4 out of 5.
Third-party tested (the specific organization isn’t listed), gluten-free.
Best Value Creatine: Nutricost Micronized Creatine Monohydrate
Rating: 4.3/5 · Price per serving: $0.20 (100 servings) · Creatine per serving: 5 g
At $0.20 per serving, this is the cheapest on our list. It’s a single-ingredient formula and third-party tested — things you usually find in pricier supplements.
The catch: Nutricost doesn’t elaborate on its third-party testing process, so we gave it 3 out of 5 for transparency. The formulation itself earned a perfect score.
Registered dietitian Perry Nix says: “It’s recommended to take 3-5 grams of creatine daily to enhance athletic performance, and Nutricost provides 5 grams daily.” Our tester reported no bloating — a pleasant surprise compared to other products he tried.
Five flavor options are available (Blue Raspberry, Fruit Punch, Pineapple Mango, Watermelon, Unflavored), sweetened with sucralose. Amazon reviewers rate it 4.6 out of 5 overall. A few mention finding pieces of plastic in their containers.
Best Flavored Creatine: Legion Recharge Post-Workout
Rating: 3.8/5 · Price per serving: $1 (60 servings) · Creatine per serving: 5 g
If unflavored creatine tastes chalky or bitter to you, try this one. Legion offers six flavors and our tester gave Strawberry Lemonade a perfect 5 out of 5: “Pretty sweet but also tart. I really liked it.”
Beyond creatine monohydrate, each serving contains 2.1 grams of L-carnitine (helps convert fat into energy) and 10.5 grams of corosolic acid (research shows it helps regulate blood sugar). No added sugars.
Labdoor tested for sport, made in an NSF-certified facility. Our tester reported no clumps or sediment — another 5 out of 5.
The downside is price. At $1 per serving, it’s one of the more expensive options on this list and scored only 1.5 out of 5 for cost. If budget matters most, Nutricost makes more sense.
Best Creatine Pills: Optimum Nutrition Micronized Creatine Capsules
Rating: 3.8/5 · Price per serving: $0.60 (two capsules) · Creatine per serving: 2.5 g
These are for people who want convenience over mixing. A bottle takes up less gym bag space than a tub of powder, and the pills go down easily — our tester rated swallowability 5 out of 5: “Tasteless aside from a slight gelatin flavor.”
One serving is two capsules with 2.5 grams of creatine. You’ll need four capsules (two servings) to hit the recommended daily dose. Three size options are available: 100 capsules for $30, 200 for $50, or 300 for $69.
Clear points out that a larger athlete — say, one weighing 100 kilograms (about 220 pounds) — would need eight capsules daily to meet the recommendation of 1 gram per kilogram of body weight. If you’re bigger in frame, powder may be easier.
Banned Substance Tested but not certified for sport. Ingredients are simple: creatine monohydrate, gelatin, magnesium stearate. Not vegan.
Best Creatine for Muscle Growth: Gnarly Creatine
Rating: 4.4/5 · Price per serving: $0.61 (90 servings) · Creatine per serving: 5 g
This one uses CreaPure® creatine monohydrate, a branded form that experts consider the gold standard for purity and effectiveness. Nastasi says: “It’s manufactured in Germany and is super pure — from a purity perspective it’s no. 1.”
NSF Certified for Sport and NSF Content Certified means it’s tested for banned substances, heavy metals, microbes, and pesticides. Clear calls this “possibly the most pure option on this list.” Formulation scored 5 out of 5.
The trade-off is mixability. Our tester noted: “It doesn’t mix very well and settles quite a bit. I usually end up stirring it several times while I take it.” Solubility scored 3 out of 5. Unflavored only.
A 30-day money-back guarantee comes with it. At $0.61 per serving, the price is reasonable for what you’re getting.
How We Picked and Tested
Our team tried more than 43 creatine supplements in total. We evaluated each one on taste, mixability, dosage, form of creatine, price, and third-party testing certifications. The general sports nutrition recommendation is 3 to 5 grams per serving for most people.
How to Choose the Right Creatine
Creatine per serving. Look for 3 to 5 grams — that’s the range research shows delivers maximum benefits. Larger individuals may need more: 0.1 grams per kilogram of body weight (about 0.045 grams per pound).
Other ingredients. Some supplements add things like HMB or L-carnitine for extra support. Decide whether you want pure creatine or a blend with additional performance ingredients.
Fillers and additives. If purity matters to you, check the ingredient list. Most powders here use only creatine monohydrate. Gummies naturally contain more added ingredients like sugar and gums.
Third-party testing. Supplements aren’t regulated by the FDA. Certifications from Informed Sport or NSF Certified for Sport give you confidence — especially if you compete in drug-tested events.
The Science: What Creatine Actually Does
Creatine phosphate is made of three amino acids — arginine, glycine, and methionine. Your body produces it naturally in the liver, kidneys, and pancreas, with about 95 percent stored in skeletal muscle.
It fuels muscles through the phosphocreatine system by helping produce ATP during maximum-effort exercises like sprints or heavy lifts lasting five to 10 seconds. Nutritionist Rob Hobson says it can also help recovery between exercise bouts and improve performance in sports involving repeated high-intensity bursts.
Benefits of Creatine
Athletic performance. Research shows creatine helps with strength, power output, and high-intensity exercise. One study found muscle power and strength increased even when subjects didn’t do any exercise — compared to a placebo group.
Muscle mass. Creatine draws more water into muscle cells, creating a volumization effect that may promote growth. A 2023 meta-analysis showed creatine combined with resistance training can increase skeletal muscle hypertrophy in both upper and lower body.
Faster recovery. Studies show it reduces immediate muscle damage after resistance training and shortens recovery time between intense bursts of exercise.
Cognition. The brain needs significant ATP for normal operation. Creatine may benefit tasks requiring speed and quick thinking.
Bone density. A 2021 study led by Dr. Darren Candow found one year of creatine supplementation plus resistance training improved bone area and muscle density in older adults — both men and women, with no sex-based differences observed.
Types of Creatine
Creatine monohydrate: The most researched form. This is what almost every product on our list uses.
Micronized creatine monohydrate: Ground into finer particles for better solubility. Research doesn’t show it’s more bioavailable than standard monohydrate, but it does mix easier.
Creatine ethyl ester: Bound to ester salts. Some studies suggest better absorption, but it’s not as effective as monohydrate overall.
Creatine nitrate: A nitrate added to the monohydrate molecule. Results on bioavailability are mixed; FDA approves 750 mg daily.
Buffered creatine: Higher pH due to added alkaline. Little difference from regular monohydrate for training gains.
The Loading Phase
A loading phase means taking 20 to 25 grams of creatine daily — split into 5-gram servings throughout the day — for up to a week. Then drop to 3 to 5 grams daily afterward.
Pete Nastasi says: “A lot of people do this to fully saturate the muscles when they first start, and it can speed up benefits by a few days.” Studies show loading can increase muscle creatine storage by 10 to 30 percent. But long term, you get the same results without loading — so skip it if you prefer.
Is Creatine Safe?
Yes. Healthy people can safely take up to 30 grams per day for up to five years, according to studies. The International Society of Sports Nutrition found “no scientific evidence that short- or long-term use of creatine monohydrate has any detrimental effects on otherwise healthy individuals.”
Who should avoid it: People with pre-existing kidney or liver conditions. Anyone taking medications affecting kidney function — like blood pressure meds or regular non-steroidal anti-inflammatory drugs — should speak to their doctor first.
Nutritionist Rob Hobson also advises against creatine for those younger than 18, since long-term effects in adolescents aren’t fully understood yet.
Your Move
- Pick a form you’ll actually take daily. Powder is cheapest. Gummies are easiest on the go. Capsules are convenient but cost more per gram of creatine.
- Aim for 3 to 5 grams per serving. If you weigh over 100 kilograms (220 pounds), you may need closer to 1 gram per kilogram — adjust your dose accordingly.
- Take it consistently, every day. Timing doesn’t matter as much as consistency. Post-workout is fine, with a meal is fine. Just don’t skip days.
