Zinc supplements can boost testosterone levels
evidence
The Claim
It is commonly believed that taking zinc supplements can significantly increase testosterone levels in men, particularly for those with low testosterone. This myth is popular among athletes and bodybuilders looking to enhance performance.
Origin
This misconception likely stems from early studies showing that zinc deficiency can lead to lower testosterone levels, leading to the assumption that supplementation would universally raise testosterone.
What Science Says
While zinc is essential for testosterone production, research shows that supplementation only increases testosterone levels in individuals who are zinc deficient. A systematic review found no significant effect of zinc supplementation on testosterone levels in healthy individuals with adequate zinc intake.
Verdict
Mostly False
