How we research
A simple, honest process — not a lab coat or a doctor’s signature.
We read the actual studies
We trace claims back to published research and label what’s strong evidence versus early or thin data.
We compare real products
We look at ingredient forms, doses, third-party testing and price — then say plainly what’s worth it and what isn’t.
We update and disclose
Guides are revisited as evidence changes, and we always disclose affiliate links and our limits.
