Evidence Quality
How well the product's primary claims are backed by published clinical research.
Scored from public data
Sources: PubMed · Cochrane · NCBI meta-analyses
Methodology
How we grade what you put in your body.
Evidence over marketing. Independent of the brands being scored.
The principle
Three commitments that govern every score.
Every product is graded the same way. Public evidence first. Brand cooperation is welcome but never required.
Evidence-led
Claims are checked against PubMed, FDA, NSF, and USP. Marketing language doesn't score.
Independent
We score brands whether they participate or not. There is no pay-to-play tier.
Live
Scores recompute when underlying evidence changes — a warning letter, a new study, a lapsed certification — all of it moves the number.
What the score measures
Six dimensions. One score.
Every product is graded on the same six dimensions. Same evidence sources, every time, no exceptions.
Formulation Integrity
Clinically effective dosing in bioavailable forms — no hidden proprietary blends.
Scored from public data
