Creatine monohydrate at 5 g a day is the only form worth buying, and more than 500 published studies say it is safe and effective at that dose. No loading required. No cycling. No special timing. It is the single most-researched supplement in sports nutrition history.
Best value:Optimum Nutrition Micronized Creatine at $0.27/day: 60 servings, banned substance tested, the most popular creatine on Amazon for a reason.
Best quality:Thorne Creatine (Creapure) at $0.49/day: German-manufactured Creapure (99.99% pure). The listing states NSF Certified for Sport and Thorne is in the NSF registry, though we could not confirm this SKU in it.
Cheapest:NOW Foods Creatine Monohydrate at $0.20/day: 120 servings from a GMP-certified facility.

All products in this table provide 5g creatine monohydrate per serving: the clinically-validated maintenance dose. Every product here works. The differences are purity sourcing, third-party testing, and price.
The shelf these five were chosen from
Original research We read the Supplement Facts panel of 1,200 on-market creatine labels in the NIH Dietary Supplement Label Database , of 2,412 listed; 969 carried a readable dose. Every figure below is against that sample, never the whole market. Candidate findings were recomputed independently in both halves of the read order; 2 of 4 held, and only those are used: including the one this page relies on, Creatine monohydrate is dosed above the alternatives.
Creatine monohydrate labels sit at a median 5 g per serving, exactly the dose the trials use, and the 90th percentile is the same figure, meaning the form barely varies. The alternatives do not: HCl labels sit at a median 2 g, buffered at 1.5 g, and magnesium chelate at 0.562 g.
| Chemical form | Labels | Median | 90th pct |
|---|---|---|---|
| Creatine monohydrate | 599 | 5 g | 5 g |
| No form named | 171 | 3 g | 9 g |
| Creatine HCl | 110 | 2 g | 3 g |
| Buffered / Kre-Alkalyn | 43 | 1.5 g | 1.5 g |
| Magnesium chelate | 39 | 0.56 g | 2 g |
Why that decides the ranking above.The rule at the top of this page, buy monohydrate, is not a brand preference or a taste. It is the only form the shelf reliably sells AT the studied dose. Every product ranked above delivers 5 g by default because monohydrate does; a premium-form product asks you to pay more for a smaller number, and the table shows how much smaller. That is why the ranking compares monohydrate products on cost and testing rather than pitting forms against each other: among the alternatives there is no dose to compare.
What this cannot tell you:This counts what labels declare per serving, not what people actually take. Someone using HCl deliberately at several servings a day closes the gap, and that is invisible here. Nor does a lower dose mean a form does not work, it is creatine, and at 3–5 g a day it should behave like creatine. It means the products are not sold at 3–5 g.

Creapure vs Generic Creatine: Is the Premium Worth It?
Creapure is a brand of creatine monohydrate manufactured by AlzChem in Germany. It is produced via chemical synthesis (not from animal byproducts) and tested to 99.99% purity. Products using Creapure are free from contaminants like dicyandiamide (DCD) and dihydrotriazine that can appear in cheaper Chinese-sourced creatine.
| Factor | Creapure (German) | Generic (typically Chinese) |
|---|---|---|
| Purity | 99.99% | 99.0-99.5% (varies) |
| Contaminant testing | Tested for DCD, DHT, creatinine | Varies by manufacturer |
| Manufacturing | Chemical synthesis in Germany | Various methods, primarily China |
| Vegan | Yes (synthesised) | Usually yes, but not always verified |
| Cost premium | ~2-3x more per serving | Baseline |
| Brands using it | Thorne, Momentous, Transparent Labs | BulkSupplements, NOW Foods, ON |
Our take: The purity difference between 99.0% and 99.99% is real but small. For most healthy adults, generic creatine monohydrate from a reputable brand is perfectly fine. Pay the Creapure premium if you are (a) a drug-tested athlete needing NSF/Informed Sport certification, (b) want the absolute highest purity guarantee, or (c) are supplementing long-term and want maximum peace of mind. The cost difference is $0.15-0.30/day, not trivial over a year, but not enormous either.
The safety record, in numbers
Creatine is among the most-studied supplements there is, and the reporting data should be read with that in mind: adverse-event reports are voluntary, carry no denominator, and are not a rate of harm among users. They are shown here because a page that sells something should show the safety data it has, not because they indicate a problem.
Evidence Highlights: Why Creatine Actually Works
500+ Published Studies
Creatine monohydrate has more published research than any other sports supplement. The International Society of Sports Nutrition (ISSN) calls it "the most effective ergogenic nutritional supplement currently available to athletes" (PMID: 28615996). This is not a hedge, it is a direct statement from the leading authority in sports nutrition.
How It Works
Creatine increases your muscles' stores of phosphocreatine, which regenerates ATP (your cells' energy currency) during short, intense efforts. More phosphocreatine = more reps, heavier lifts, faster sprints, quicker recovery between sets. The mechanism is clear, the effect is consistent, and it works for trained and untrained individuals, men and women, young and old.
Strength and Muscle
A meta-analysis of 22 studies found creatine supplementation increased maximum strength by an average of 8% and repetitions to failure by 14% compared to placebo (PMID: 14636102). These are large, reliable effect sizes by supplement standards.
Cognitive Benefits
Your brain uses creatine the same way your muscles do. A 2003 randomized controlled trial by Rae et al. found that 5g/day of creatine for 6 weeks significantly improved working memory and processing speed in vegetarians (PMID: 14561278). Benefits appear most pronounced during sleep deprivation, mental fatigue, and cognitively demanding tasks. This is an active area of research with consistent mechanistic support.
Creatine and Depression
A 2019 review by Kious et al. examined the relationship between creatine and depressive disorders. Preliminary evidence suggests creatine supplementation may have antidepressant effects, potentially by restoring brain energy metabolism. The authors noted that brain phosphocreatine levels are reduced in depression, and creatine supplementation may help normalise this. More clinical trials are needed, but the biological rationale is strong.
The Hair Loss Myth
This is the most common concern about creatine, so let's address it directly.
In 2009, a study of 20 South African rugby players found that a creatine loading protocol (25g/day for 7 days, then 5g/day for 14 days) increased DHT (dihydrotestosterone) levels by 56% (PMID: 19741313). DHT is linked to male pattern baldness in genetically predisposed individuals, which sparked widespread concern.
Here is what the evidence actually shows:
- This is ONE study with 20 participants. It has never been replicated in the 17 years since publication.
- DHT levels stayed within normal physiological range even after the increase.
- Multiple subsequent studies measuring testosterone and DHT during creatine supplementation found no significant changes.
- The ISSN position stand (2017) states: "There is no direct evidence that creatine supplementation promotes hair loss."
- No study has ever measured actual hair loss in creatine users, the DHT study only measured a hormone level, not clinical hair loss outcomes.
Bottom line: If you are genetically predisposed to male pattern baldness (family history), the theoretical risk is not zero but is very small and not supported by replicated evidence. For the vast majority of people, this is a non-issue. Do not let one unreplicated study from 2009 prevent you from using the most well-researched supplement available.
Verification check · Creatine
What we could and could not verify about Creatine
3 of the 6 are confirmed in NSF/ANSI 173: BulkSupplements Micronized Creatine Monohydrate (500g) and Momentous Creatine Monohydrate (Creapure, 90 servings) and 1 more. The other 3Creatine products we track are simply not listed, which is an absence of independent confirmation and not evidence against them.
Method: our Creatine roster matched against the full public registries of third-party-certified supplements in the US, NSF/ANSI 173, USP Verified and Informed Sport, 5,317 listings, retrieved 2026-08-25. Absence means nobody independent has checked that Creatine product, not that it failed. Full method and limitations.

Three checks on the Amazon listing itself
- Who is selling it. The “Sold by” line should read the brand, Amazon, or the brand’s named distributor. Amazon commingles inventory for many ASINs, so a third-party seller on a supplement listing is the one place a counterfeit or expired unit can enter.
- The lot and the expiry on arrival. For a product with a certificate lookup or a registry listing, the lot number on the container is what you check, not the listing. A lot older than the certificate date, or an expiry inside a year, is a reason to return it.
- The serving count, not the piece count. The per-day figures above use the label’s serving; a listing that says “240 count” at two pieces a serving is 120 days, and Amazon’s own “price per count” ignores that.

Frequently asked questions
What is the best creatine supplement?
Plain creatine monohydrate powder at 5g/day. For value: Optimum Nutrition Micronized Creatine ($0.27/day). For quality: Thorne Creatine (Creapure; NSF-listed brand, SKU unconfirmed) ($0.49/day). For budget: NOW Foods ($0.20/day). Skip HCl, buffered, and ethyl ester forms. See our forms comparison.
Is loading creatine necessary?
No. Loading (20g/day for 5-7 days) saturates muscles in about a week. Taking 3-5g/day reaches the same level in 3-4 weeks. Loading is faster but not required and can cause GI discomfort. Both protocols produce the same end result, see how long creatine takes to work for the full timeline breakdown.
Does creatine cause hair loss?
Based on ONE unreplicated 2009 study of 20 people that found a DHT increase within normal range. Multiple subsequent studies found no effect. The ISSN says no direct evidence. If you have a strong family history of male pattern baldness, the theoretical risk is very small but not zero. For everyone else, this is a non-issue.
Can women take creatine?
Yes. Creatine is safe and effective for women. Women typically have 70-80% lower muscle creatine stores and may see proportionally larger benefits. It does not cause bulkiness, the 1-3 lbs of water weight gain is intracellular (inside muscles), not subcutaneous fat. The ISSN explicitly includes women in their recommendations.
Does creatine have cognitive benefits?
Emerging evidence says yes. A 2003 RCT found creatine improved working memory and processing speed (PMID: 14561278). Reviews have reported preliminary evidence for antidepressant effects. Your brain uses creatine for the same ATP regeneration as muscles. Benefits are most pronounced during sleep deprivation and mental fatigue.
