Two of our registry lists were reviewed by a dietitian before publishing, and so were five of our protein bar lists. This page names each reviewer, says what she reviewed and when, and says what a review on this site is and is not.
What a review is, and what it is not
A reviewer reads a list before it is published and returns written comments on it. Each section below says what that review covered; a page names a reviewer’s call where a row rests on it. A review is not an endorsement of any product, and it is not a statement that a product is safe or suitable for you. The Protein Index makes no medical claims. Only the registry entry, checked on the day you buy, says what is listed today.
