Many athletes can be deficient due to sweat loss. ZMA (Zinc Monomethionine Aspartate, Magnesium Aspartate, and Vitamin B6) is a popular combination marketed for improving sleep quality, recovery, and testosterone levels. While magnesium and zinc are beneficial if deficient, ZMA's direct impact on testosterone in non-deficient individuals is less clear. Focus on getting enough Zinc and Magnesium first.
