How to Evaluate Supplement Health Claims

Strong words can make weak evidence sound decisive. A better process is to identify exactly what claim is being made and what kind of evidence would actually support it.

Identify the claim

“Supports healthy blood sugar” is not the same statement as “treats diabetes.” Product pages should not blur that distinction.

Match evidence to the claim

An ingredient study supports conclusions about that ingredient under the conditions studied. It does not automatically prove the finished commercial product produces the same outcome.

Watch for borrowed authority

Logos, references to scientific databases and medical imagery can create an impression of validation. Check whether the cited research actually tested the product or simply relates broadly to one ingredient or mechanism.
