How we review

We start from the Supplement Facts panel. Every active ingredient is checked against the amount used in published human studies, so an ingredient that is present at a fraction of the studied dose is scored as such. We read widely across the manufacturer's claims, third-party evidence, buyer feedback and refund terms, and we say plainly who a formula is for and who should skip it. Where a review cites a figure, it is attributed to a named source on the page.

The NutraRank Score is an editorial judgement on a five-point scale. It is not an average of other people's ratings, and we never publish an invented review count or star average. Five things decide it:

Ingredient evidence How well the active ingredients are supported by human research.
Doses vs studies Whether the label amounts match what the studies actually used.
Label transparency Full disclosure, no proprietary blends hiding the doses.
Value for money Cost per serving against comparable formulas and single ingredients.
Guarantee and refunds Length and real-world experience of the money-back guarantee.
