Best Creatine in 2026, by Evidence

Last verified November 2, 2026. Every grade, certification and price on this page links to the source we checked. Where we couldn't confirm something, we say so.

We have not tested these products ourselves; label figures come from the retailer and brand pages cited below, and lab results come from the named testers.

The short answer

Creatine monohydrate is one of the best-studied supplements in sport. Taken alongside resistance training, it adds strength and lean mass in adults of all ages (grade A under 50, grade B in older adults).⁴⁵⁶ The cheapest certified monohydrate powders work as well as any premium form. No other form has beaten monohydrate in a head-to-head trial.¹¹²

• Buy plain monohydrate powder. Certified tubs cost about $0.19 to $0.49 per 5 g serving.¹⁶¹⁹
• Skip gummies. Two independent lab tests found that many creatine gummies held a fraction of the label amount, or none.¹²¹³
• Pick a certified product (NSF Certified for Sport or Informed Sport) if you are drug-tested, or if you just want a check on what is in the tub.¹⁵
• It is safe for healthy people at the doses studied. It does not harm healthy kidneys, and the only trial that looked directly at hair found no hair loss.¹¹⁰⁹

Status snapshot: what certification tells you

Creatine is sold as a dietary supplement in the US. The FDA does not review supplements for safety, purity or label accuracy before they are sold. That is why independent certification matters here.

Mark on the label	What it means	Products on this page
NSF Certified for Sport	NSF tests the product for banned substances and checks that the label matches the contents. Listings are by product and often by lot, so check your lot number.1514	Thorne Creatine, Momentous Creatine
Informed Sport	Every batch is tested for banned substances before release.2122 The Informed Sport directory lists NOW Sports Creatine Monohydrate Powder and Sports Research Creatine Monohydrate as certified products.161714	NOW Sports Creatine, Sports Research Creatine
Informed Choice	The same tester as Informed Sport, but with less frequent batch testing. Verified Supplement Data lists it for Optimum Nutrition creatine (300 g tub).14	None of our picks
Creapure	A trademarked creatine monohydrate made in Germany. It is an ingredient brand, not a third-party test. We found no trial showing it works better than other pure monohydrate.	None of our picks. Momentous says it no longer sources Creapure.18
"Third-party tested" with no name	Says nothing you can check. Ask for a certificate of analysis.	None of our picks

*We confirmed the two Informed Sport listings in the Informed Sport directory. We could not get a full NSF Certified for Sport listing to load, so NSF marks come from the brand or retailer listing and a third-party registry, as cited. Confirm with the certifier before you rely on it for drug testing.

Forms graded

Grades here are about the form, not about creatine in general. A = the form used in nearly all the research. D = no evidence it is better, or evidence that it underdelivers.

Form	Grade	What the evidence says	Our take
Monohydrate powder (including micronized and Creapure)	A	The form used in almost every trial behind the benefits on this page.14	Buy this.
Monohydrate capsules	Aform / C (practicality)	Same compound. Capsules usually hold well under 1 g each, so a 5 g serving takes several capsules.	Fine if you hate powder. Costs more per gram.
Buffered (Kre-Alkalyn)	D	In a 28-day trial of 36 trained people, buffered creatine at the label dose (1.5 g/day) or at monohydrate-matched doses did not raise muscle creatine, strength or lean mass more than monohydrate. It did not cause fewer side effects.11	No reason to pay more.
Creatine HCl	D	Marketed as more soluble, so you need less. We found no trial showing better muscle creatine or results than monohydrate. The 2021 ISSN review takes up whether other forms are similar or superior to monohydrate as one of its common questions.2	No reason to pay more.
Gummies	D	In a 2024 test of 12 brands, NOW found half below their label claim.12 In a 2025 test, SuppCo found 4 of 6 gummies had trace or no creatine. All 5 powders it tested passed.13	Avoid unless a recent independent test backs the exact product.
Liquids and "creatine drinks"	D	Creatine breaks down to creatinine over time. SuppCo found high creatinine even in the two gummies that passed, which it calls a sign of degradation.13	Avoid ready-to-drink products.

Gummy tests in detail

• NOW Foods, February 2024. NOW tested 12 gummy brands by HPLC. Six failed their label claim: Astro Labs, Beast Bites, Create, Con-Cret, Greabby and Njord. Con-Cret's maker disputed the result and said its own accredited lab found more than the label claim.¹² NOW sells creatine powder, so it is not a neutral party.
• SuppCo, June 2025. 11 products bought off the shelf and tested at an ISO 17025-accredited lab. All five powders (BulkSupplements, Nutricost, Sports Research, NatureBell, Jocko Fuel) were 98–101% pure. Happyummmm and DivinusLabs gummies had trace creatine, and EcoWise and Vidabotan had none detected. Force Factor (6.3 g vs 5 g claimed) and Create (4.59 g vs 4.5 g) passed.¹³
• The two tests disagree on Create. It failed in 2024 and passed in 2025. A brand can change its formula or supplier, so one passing test does not settle it.¹²¹³

Evidence map: graded by outcome

A = consistent meta-analyses of randomized trials. B = meta-analyses with a smaller or less consistent effect, or a narrower group. C = small, low-certainty or single trials. D = no effect, or too little evidence to say. X = evidence of harm.

Outcome	Grade	What the best evidence found	Study doses
Strength with resistance training (adults under 50)	A	23 trials: about 4.4 kg more on upper-body lifts and 11.4 kg more on lower-body lifts than placebo, with no variation between studies (I² = 0%).4	Varied; most used a loading phase then 3–5 g/day
Lean mass and strength in older adults	B	22 trials (721 people, mean age 57–70): 1.37 kg more lean mass than placebo, and small strength gains.5 A 2021 update found 1.32 kg, with or without a loading phase.6	≤5 g/day and >5 g/day both worked for lean mass
Women	C	In the under-50 meta-analysis, only 2 of 23 trials were in women. Gains were smaller and not statistically significant, but the sex difference itself was not significant either.4 More trials are needed.	As above
Recovery from hard exercise	C	The ISSN lists post-exercise recovery and injury prevention among possible benefits, not proven ones.1	Not standardized
Memory and cognition	C	16 trials (492 people): small improvement in memory (moderate certainty) and processing speed (low certainty). No effect on overall cognition or executive function.7	Monohydrate in all trials; doses varied
Thinking during sleep deprivation	C	One crossover trial of 15 people: a single high evening dose improved memory and reaction time during a night without sleep. The effect was short-lived. The lead researcher said the dose is not advisable at home.8	A single dose far above the usual 3–5 g
Kidney function in healthy people	No harm shown	A meta-analysis concluded creatine does not damage the kidneys at the doses and durations studied.10 Blood creatinine rises because creatine breaks down into it, which can look like a kidney problem on a lab test.23	Studied up to 30 g/day for 5 years in some groups1
Hair loss	No harm shown	A 12-week randomized trial in resistance-trained men (45 randomized, 38 finished) found no difference from placebo in DHT, the DHT-to-testosterone ratio, hair density, follicular unit count or hair thickness.9	5 g/day

The hair-loss worry traces to one 2009 study of rugby players that reported a rise in DHT. That result has not been replicated, and it did not measure hair.³⁹

Our picks and how we chose them

We set these criteria before we looked at any product. Commission is not one of them.

1. Creatine monohydrate, the form with grade-A evidence.
2. Plain powder with no proprietary blend, so you know you get 5 g per serving.
3. NSF Certified for Sport or Informed Sport, per the retailer listing or a registry we could cite.
4. Cost per 5 g at a named retailer on November 2, 2026.
5. No unresolved label-accuracy flag.

Some links on MoveWell earn us a commission. That played no part in which products are listed here or in what order.

Best value: NOW Sports Creatine Monohydrate

A 1 kg bag gives about 200 servings of 5 g, and lists Informed Sport.¹⁶ At $38.46 when we checked, that is about $0.19 per 5 g, the lowest of our picks. Caveat: NOW also ran the 2024 gummy tests and sells this powder.¹²

Also good value: Sports Research Creatine Monohydrate

A micronized monohydrate in a 1 kg tub (200 servings) with Informed Sport certification, per the retailer.¹⁷ About $0.25 per 5 g. It also passed SuppCo's 2025 lab test (98–101% purity across the five powders).¹³

Best for drug-tested athletes: Thorne Creatine

Thorne lists NSF Certified for Sport, which matters if your sport or league asks for that mark. A 450 g tub gives 90 servings of 5 g.¹⁹ At $44.00 it is about $0.49 per 5 g. NSF lists it by lot, so match the lot on your tub to the NSF listing.¹⁴¹⁵

Also NSF Certified for Sport: Momentous Creatine

Monohydrate, 5 g per scoop, 90 servings (450 g), NSF Certified for Sport per Momentous.¹⁸ At $42.99 one-time on livemomentous.com when we checked, about $0.48 per 5 g (less on subscription). Momentous now says it no longer sources Creapure and uses its own "Signature Spec" creatine; older retailer listings, including one we first used, still describe the Creapure version with Informed Sport as well. Check the tub you receive. Creapure was a sourcing choice, not a proven performance advantage.

Picks compared: cost per 5 g

Price checked November 2, 2026. Cost per 5 g is the price divided by the number of 5 g servings. Prices change often.

Product	Form	Size and servings	Certification (as cited)	Price	Cost per 5 g
NOW Sports Creatine Monohydrate	Monohydrate	1 kg, about 20016	Informed Sport*	$38.46 at Vitacost	$0.19
Sports Research Creatine Monohydrate	Micronized monohydrate	1 kg, 20017	Informed Sport*	$49.47 at Vitacost	$0.25
Momentous Creatine	Monohydrate ("Signature Spec"; no longer Creapure)	450 g, 9018	NSF Certified for Sport (per brand)*	$42.99 at livemomentous.com	$0.48
Thorne Creatine	Monohydrate	450 g, 9019	NSF Certified for Sport (by lot)*	$44.00 at Vitacost	$0.49
BulkSupplements Creatine Monohydrate (also considered)	Micronized monohydrate	500 g, about 10020	NSF Certified for Sport on some listings and lots only*	$19.97 at Walmart	$0.20

*Per the retailer or brand listing or Verified Supplement Data. Informed Sport listings for NOW Sports and Sports Research were confirmed in the Informed Sport directory on November 2, 2026; NSF listings could not be confirmed in NSF's directory (its public listing page would not load past the first entries).

Products we held or excluded

• BulkSupplements: cheap, and it passed SuppCo's test.¹³ NSF lists some lots, but the 500 g Walmart listing we checked does not show the NSF badge.²⁰¹⁴ Buy it if price matters most and you are not drug-tested.
• Nutricost: passed SuppCo's potency test, but we found no NSF or Informed listing.¹³¹⁴
• Optimum Nutrition Micronized Creatine: listed as Informed Choice for the 300 g tub.¹⁴ We did not check a US price, so we left it out of the table.
• Transparent Labs Creatine HMB: NSF Certified for Sport, but it adds HMB and costs about $1.67 per serving.¹⁴ HMB is outside the scope of this page.
• All creatine gummies: excluded as a category until the same product passes repeated independent tests.¹²¹³
• Creatine HCl and buffered creatine: excluded because no trial shows an advantage over monohydrate.¹¹²

How much: doses used in studies

These are the doses researchers used. They are not a personal recommendation. If you have a medical condition or take prescription drugs, ask your clinician first.

• Loading: 20 g a day, split into four 5 g doses, for 5–7 days, then 5 g a day. This was the monohydrate protocol in the buffered-creatine trial.¹¹
• No loading: 3–5 g a day reaches the same muscle levels more slowly. In older adults, lean mass gains held up without a loading phase.⁶³
• Upper end studied: the ISSN position stand describes doses up to 30 g a day for 5 years as well tolerated in the groups studied.¹

Safety and who should avoid it

Concern	What the evidence says
Kidneys	No harm in healthy people at studied doses.101 If you have kidney disease, ask your kidney doctor first. Tell your clinician you take creatine before a blood test, because it raises creatinine.2
Water weight	Some studies show water retention in the first days of use. Any effect is temporary.3 Body weight can go up because muscle holds more water and creatine.
Hair loss	No effect on DHT or hair in a 12-week trial.9
Cramps and dehydration	The ISSN review addresses these as misconceptions.2
Teens, pregnancy and breastfeeding	The ISSN reports research across ages and in pregnancy, but these groups should not start on their own. Ask a clinician.1
Drug-tested athletes	Creatine is not banned, but any supplement can be contaminated. Use a lot-tested certified product.15

Myths

Myth	What the evidence says
"Creatine is a steroid."	It is not. The ISSN review addresses this directly.3
"Creatine makes you bald."	Based on one unreplicated 2009 DHT result. A trial that measured hair found no effect.9
"It damages your kidneys."	Not in healthy people at studied doses. Higher creatinine on a blood test is expected.102
"HCl or buffered creatine absorbs better, so you need less."	Buffered creatine did no better than monohydrate in a head-to-head trial.11
"You must load."	Loading gets you there faster. 3–5 g a day gets you there in a few weeks.3
"Gummies are just as good."	Not reliably. Many tested gummies were underdosed.1213

FAQ

Is creatine monohydrate the best form?

Yes, on the evidence. Almost all trials used it, and a buffered form did no better in a head-to-head trial.¹¹¹

Does creatine work for women?

Probably, but there are far fewer trials. In the 2024 meta-analysis only 2 of 23 trials were in women, and their gains were smaller but not significantly different from men's.⁴

Is creatine worth it after 50?

With resistance training, yes on current evidence. Two meta-analyses found about 1.3–1.4 kg more lean mass than training alone.⁵⁶

Does creatine help your brain?

Maybe a little for memory. The evidence is moderate certainty for memory and low for other measures.⁷ The sleep-deprivation result comes from one small trial at a very high dose.⁸

Will creatine make me gain weight?

You may gain a little weight early on, mostly water held in muscle. It is temporary.³

Do I need NSF Certified for Sport?

Only if you are drug-tested, or want the strongest check on the contents. Informed Sport also batch-tests for banned substances.¹⁵¹⁴

Are creatine gummies a scam?

Not all, but many failed independent tests in 2024 and 2025. Two passed in 2025, and one of those had failed in 2024.¹²¹³
