Evidence
Overhyped

Marketing intensity 70 of 100. Evidence strength 35 of 100. Verdict: Overhyped.

Evidence
Slightly overhyped

Marketing intensity 65 of 100. Evidence strength 55 of 100. Verdict: Slightly overhyped.

Useful for an actual deficiency and possibly for shortening colds if you start lozenges fast. As an everyday testosterone or immunity booster in well-fed people, it's oversold.
