# Can a supplement say “#1 doctor recommended”?

Source: https://claimsverified.org/claims/number-one-doctor-recommended/

Only with a defensible survey behind it, which almost no brand holds. It is a superiority claim, so it needs a documented survey of the right population asked the right question. Remove it unless that survey exists. The survey has to exist before the claim runs, not after someone asks.

Why it fails

## The rule this runs into.

Requires a defensible survey. Almost never held.

We file this under substantiation and rate it high. It is enforced by FTC, Amazon, Meta, which matters because a single phrase can fail in more than one place at once: a listing suppression, an ad-account review and a warning letter are three different consequences of the same sentence.

What to say instead

## The wording that passes.

This is the rewrite an audit ships for this phrase: the strongest wording the standard allows, in the words we would hand you.

The rewrite the standard allows

Remove unless a documented survey exists.

Every structure/function claim on this page still needs the FDA disclaimer wherever it appears. That requirement has [its own ruling](https://claimsverified.org/claims/fda-disclaimer/).
