Supplements aren’t approved before they’re sold. Labels can exaggerate, blends can hide underdosing, and a bottle that failed a purity test can sit on the same shelf as one that passed. The information to tell them apart exists — scattered across certificates, standards documents, and journals nobody reads at the checkout.

WhatSupp puts that information in one place, in plain English, at the moment you’re deciding. Paste a link, get a grade, see the evidence. Your guide to smarter supplements.

We answer to buyers, not brands: no sponsorships, no paid placement, no affiliate bias in grades. How every score is built is public in our methodology.
