THE FOUNDATION

Start with what matters.

Before comparing ingredients, learn how to read a label, interpret a study and understand what a laboratory report can—and cannot—tell you.

QUALITY / 6 MIN

What a Certificate of Analysis actually tells you

How to match the product, lot number, test panel and reported result without confusing laboratory testing with clinical benefit.

Are dietary supplements FDA approved?

No. Learn how U.S. supplement regulation works, what manufacturers remain responsible for and which quality signals matter.

HOW OYAH READS RESEARCH

A headline is not the evidence.

We look past the conclusion. We check who participated, what researchers used, how long the study lasted and which outcomes changed.
