The Protein IndexREAD THE LABEL

An independent index of protein products

Built for people who have to read the label.

Checked by a person, field by field

Every record stamped Verified was reviewed field by field by a person, against the manufacturer’s label and source, on the date it shows.

Allergen statements are quoted word for word from the manufacturer’s declaration. When two sources disagree, a person decides: software never picks a winner.

Why this exists

Verification standards from elite sport, applied to the whole shelf

Made by the father of competitive athletes, after one of them reacted to an undeclared allergen at an international event. It’s maintained to the verification standard that high-level sport demands. Nothing here is inferred. If the label has a line for it, we quote it. If it doesn’t, we say “not listed”. We believe nobody should find out what a product contains the hard way.
