Read the evidence before the label

Make a decision, not a guess.

Every guide is organized around the three questions that change a purchase: does it work, what amount was studied and what could make it a bad fit?

01

Evidence

Strong, moderate or emerging based on the quality and consistency of the available research.

02

Dose & Form

The forms and amounts used in research, with the label details that matter when products look similar.

03

Safety

Interactions, common cautions and the reasons a useful supplement may still be the wrong choice.

The notes behind the notes

Independent first. Affiliate second.

Evidence grades are not product ratings, and affiliate availability never changes a grade. Product recommendations will only appear after the label, dose, form, testing and price have been checked.
