The supplement aisle is built so that comparing two products is hard. We write the reference material that makes it easy — how to read a panel, what a certification actually certifies, and how to tell a real trial from a decorative one.
Everything here is free to read and free of gates. We take affiliate commissions on some links, we say so on every page, and it does not change what we publish. Our review method and our editorial policy are written down so you can hold us to them.

How to read a supplement facts label
The panel on the back of the bottle is regulated, but it is not a quality score. Here is what each line legally means, and what it deliberately leaves out.
What we will not do
We do not publish reviews of products we have not examined, we do not run testimonials we cannot verify, and we do not describe any supplement as a treatment for a disease. If a page here ever reads like it was written to sell rather than to inform, tell us and we will fix it or take it down.
