Ingredient transparency for protein & collagen.
We review only what a brand lists on the label. Every product gets a green / yellow / red rating and links to neutral public studies for every flagged ingredient. No health advice. No paid basic ratings.
Editorial opinion based on listed ingredients. Not medical or nutritional advice.
The rating system
Three verdicts. One document stamp.
Our methodology weighs ingredient categories only — what a brand prints, not what a lab would measure. Read how we rate.
