Registry check · Creatine
Does anyone independently verify Creatine supplements?
5 of the 6 Creatine products on this page are confirmed in Informed Sport / Informed Choice and NSF/ANSI 173: BulkSupplements Micronized Creatine Monohydrate (500g); Momentous Creatine Monohydrate (90 servings); NOW Sports Creatine Monohydrate Powder (600g); Thorne Creatine (90 servings); Transparent Labs Creatine HMB (30 servings). NOW Sports Creatine Monohydrate Powder (600g); BulkSupplements Micronized Creatine Monohydrate (500g) do not show the mark on the listing, so the table’s certification column, which repeats the listing, does not show it either. For the others, the listing may name a certification, but we did not find it in a public registry — that is not evidence against them, only an absence of independent confirmation.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the Creatine dose column either way.
The 6 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What Creatine labels show
Priced per day, these creatine products run $0.13 to $1.67 — a 13× gap between the cheapest and dearest creatine here, across 6 brands.
Servings here are close enough to compare directly, so the gap is a real one: NOW Foods at $0.13 states about the same dose per serving as Transparent Labs at $1.67.

Dose check · Creatine
Does one serving reach the studied Creatine monohydrate dose?
The research on Creatine monohydrate uses 3 g to 5 g (grams monohydrate). Every one of the 6 products here reaches the low end in a single serving, so one serving a day covers the studied dose.
The label trap on Creatine: Monohydrate is the definitively best-studied form. HCl/buffered/'advanced' forms are marketed at a premium with no proven advantage. Look for plain creatine monohydrate (Creapure is a quality-signalling brand of it).
Method: studied range from our own Creatine dosage guide (PMID 28615996), checked against the 6 products above that state a dose — capsules in whole servings, powders in fractions. Trial doses, not a prescription.
The shelf · Creatine
A Creatine day costs 12.8× more at one end of this table than the other
NOW Sports Creatine Monohydrate Powder (600g) is the cheapest day on this page at $0.13 and Transparent Labs Creatine HMB (30 servings) the priciest at $1.67. Both state about the same dose per serving, so paying 12.8× more does not buy more Creatine. Check what the pricier product can actually be shown to contain before you pay for it.
Method: the 6 Creatine products above, compared on label facts, serving size, servings per container, form, price. Not a dosing recommendation.
The evidence · Creatine
What the published reviews of Creatine concluded
- Effect of creatine supplementation on kidney function: a systematic review and meta-analysis. · BMC nephrology, 2025
“Creatine supplementation is associated with a modest, transient increase in serum creatinine levels, likely due to metabolic turnover rather than renal impairment. No significant changes were observed in GFR, suggesting preserved kidney function.”
- Does creatine cause hair loss? A 12-week randomized controlled trial. · Journal of the International Society of Sports Nutrition, 2025
“This study was the first to directly assess hair follicle health following creatine supplementation, providing strong evidence against the claim that creatine contributes to hair loss.”
- Creatine monohydrate supplementation during eight weeks of progressive resistance training increases strength in as little as two weeks without reducing markers of muscle damage. · The Journal of sports medicine and physical fitness, 2019
“Cr increased muscular strength in as little as two weeks during a resistance training program; however, this was not accompanied by decreased muscle damage. Greater muscle damage with Cr may be due to a greater training intensity enabled by Cr supplementation.”
- Creatine supplementation during resistance training in older adults-a meta-analysis. · Medicine and science in sports and exercise, 2014
“Retention of muscle mass and strength is integral to healthy aging.”
Method: PubMed searched in humans for systematic reviews, meta-analyses and randomised trials with Creatine in the title; these 4 of the 29 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether Creatine will work for you — each of these reports an average across trials published 2014–2025, and null findings are shown here as readily as positive ones.
How these 6 Creatine products were ranked
5 of these 6 are confirmed in a certifier's registry — the only creatine rows where the claim is independently backed — and the rest are ranked on cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever creatine you buy. Full methodology.
