Our promise
Why readers trust Nutrition Reviews
No pay-to-play
Brands can’t buy a review, a ranking or a score. Affiliate commissions never change our verdicts.
Evidence first
We grade doses and claims against published research — and say so when the evidence is thin.
Honest about limits
We don’t pretend to run a lab. We show our sources, our math and the date we last checked.
