The Standard · Claims library

What every claim must prove.

What counts is what the claim means to a shopper. Having an ingredient in the bottle rarely proves the product actually does the thing. For each of 30claims, here's what it tells a buyer, the evidence we need to see, what doesn't count, the wording that's allowed, and what we publish once it checks out.
