What is ZMA and how does it relate to testosterone production?
ZMA is a supplement that combines zinc, magnesium aspartate, and vitamin B6, and it is often marketed as a testosterone booster. Zinc is essential for testosterone synthesis, and magnesium deficiency can impair sleep quality and reduce free testosterone levels. However, in individuals who are already zinc and magnesium sufficient, ZMA supplementation does not result in meaningful testosterone elevation.
