What a product page here will show you

Most supplement pages are written to sell. These four hold whatever that costs.

• The dose in the bottle, not the name on it

  No evidence appears on a product until someone has read its physical label. Five grams of creatine and five hundred milligrams are not the same product, and a trial run at one says nothing about the other.

• Nothing about a disease

  Measured endpoints only — blood pressure, a marker, a performance test. Not because we decline to write it: a claim about a disease cannot be reached from a page with a price on it at all.

• What it interacts with, before you buy

  Documented interactions sit above the buy button rather than below it. Anyone who has to scroll past a purchase control to find a warning has been served badly, and that is a layout decision somebody made.

• The findings that are bad for us

  Including the trials that found nothing, at the same size as the ones that did, next to the thing you are being asked to pay for. Nothing about selling an item can move its grade. How a grade is computed.
