Signature ZMA

Bodybuilding.com Signature ZMA supplement contains a patented blend of zinc, magnesium, and vitamin B6, which can help improve your sleep quality and increase your anabolic hormone levels for optimal muscle growth. Both magnesium and zinc are minerals required by the body for the maintenance of healthy muscles (1). Vitamin B6 is added in order to enhance absorption. Magnesium plays a fundamental role in over 300 different metabolic reactions (1).

There have been studies showing that magnesium can help improve insomnia, sleep efficiency, sleep time, and early morning awakening (2). Individuals who are especially at risk for magnesium deficiency are older adults, diabetics, and those with gastrointestinal disorders. Zinc deficiency has its fair share of downsides as well, being shown to hinder testosterone production and have a negative impact on muscle function (3).

Athletes frequently lose both magnesium and zinc after intense exercise, which results in diminished recovery in the days following (4). In one study, ZMA was found to help enhance anabolic hormonal profiles, reduce catabolism, improve immune status, and/or improve adaptations to resistance training (5).
