How evidence is labeled

Know what kind of evidence you're reading.

Rx

FDA-labeled product and named indication

H

Human research or regional clinical use

C

Community-discussed; not clinically established

P

Preclinical or insufficient human dosing evidence

Popular does not mean proven. Animal research does not establish human benefit. Community ranges are not medical recommendations.
