How to check a supplement claim without turning reviews into evidence
Turn an advertisement into a clear research question and separate the exact product claim from testimonials, ingredient background and original research.

A record, not a safety certificate
Use this list to identify unfinished shopping questions. Checking every box does not establish that a supplement is safe, effective or right for you. If you cannot complete an item, write down what is missing before you decide whether to buy. The list deliberately includes both product and checkout details because a comparison can fail through missing information on either side.
For an illustrative shopping session, first photograph the exact label, then record a one-time checkout total. Calculate its cost per serving. If the seller advertises a certification, verify the exact product in the certifier’s directory rather than relying on a logo in a marketplace photo. Bring your medicine and supplement list to a pharmacist when asking about suitability.
