Separate mechanism from outcome

A pathway or biomarker does not automatically prove a meaningful consumer outcome.

Separate ingredient from finished product

Evidence for one ingredient does not automatically validate a multi-ingredient brand.

Interrogate certainty

Guaranteed, permanent, instant and works-for-everyone language should raise skepticism.

Check the population

A result in a specific clinical population may not generalize to everyone.

Look for transparent sourcing

You should be able to tell merchant facts, research findings and editorial interpretation apart.

Health note: Persistent erectile difficulties, major libido changes or unexplained fatigue can have multiple causes. Consider medical evaluation rather than relying solely on a supplement.
