How we rank
We rank by cost-per-dose — price ÷ servings, normalized to the daily dose (5 g/day)— so bottle sizes and strengths compare fairly. Prices are scraped at publication and re-checked when the catalog refreshes (see the “Prices checked” stamp above). There is no paid placement and no kickback for ordering. Full methodology · Editorial standards.
That cost-per-dose number is the one most retailers and review sites leave out — they’ll show a sticker price and a serving size, but not what a day actually costs. We compute it for every product so you can compare like for like.
When cheapest ≠ best value
The cheapest bottle isn’t automatically the best value: a low-absorption form (magnesium oxide is the classic example) can look cheap per milligram yet deliver less of what you actually absorb. Where forms differ, compare cost per absorbed or elemental unit, not the compound weight on the label. A bigger bottle isn’t automatically cheaper per dose either — this list already ranks by cost per gram of active, so a larger count only wins if it truly costs less per serving. Compare Creatine Monohydrate forms.
Our data on this: the big bottle saves a median ~86% per serving · the gummy tax (~2× more) · the form premium · the price spread.
Full ranking by cost per dose
Cost per gram of active normalizes price across scoop sizes — a 20 g and a 25 g serving compare fairly. Top 20 of 40 shown.

Creatine Monohydrate brands we compare — which are third-party tested?
3 of the 16 brands ranked above appear in an independent certifier's own public registry. A certification confirms the label matches the contents — it says nothing about how well the supplement works, and an uncertified brand is not automatically worse.

What is the highest-quality Creatine Monohydrate supplement?+
Of the 16 creatine monohydrate brands ranked here, 3 hold a third-party certification we could verify in a public registry: BulkSupplements.com (NSF Certified for Sport), Optimum Nutrition (NSF Certified for Sport), Thorne (NSF Certified for Sport). Certification means an independent lab confirmed the label matches the contents and screened for contaminants — it does not rate how well the supplement works. The cheapest certified option is Optimum Nutrition Creatine at $0.05 per gram.
Which Creatine Monohydrate brands are third-party tested?+
BulkSupplements.com — NSF Certified for Sport; Optimum Nutrition — NSF Certified for Sport; Thorne — NSF Certified for Sport. We only count a brand as tested when it appears in the certifier's own public registry (USP Verified, NSF Certified for Sport, Informed Choice), never on a claim printed on the label. The remaining 13 brands on this page have no certification we could verify.
Which Creatine Monohydrate is the top rated?+
We don't republish marketplace star ratings — they belong to the retailer, they move constantly, and a 4.6 average tells you nothing about what is in the capsule. The two things you can verify are what a dose costs and whether an independent lab checked the label. On both counts, Optimum Nutrition Creatine stands out: NSF Certified for Sport certified at $0.05 per gram.
Independent testing
3 of 16 tracked Creatine Monohydrate brands here are flagged as carrying independent third-party testing — a voluntary check of a product's identity, potency and contaminants by an outside lab. It's a quality signal, not a value or efficacy claim. Confirm any brand's current status on the official registries:
Testing status is self-reported by the brand or drawn from public certification and may change — always verify on the official registry before purchase.
