A good night’s sleep is key to your overall health — and your goals in the gym. Without proper sleep, your body can’t repair itself. Signature ZMA is a patented blend of zinc, magnesium, and B6. Clinical research has shown that this ZMA blend, when given to trained athletes before bed, may support improvements in sleep quality, strength, power, and testosterone levels.* Zinc and Magnesium both also play vital roles in hundreds of bodily functions necessary to performing your best while Vitamin B6 supports their absorption.*
Zinc is important to countless processes in the body, including immune function[3,4] and protein synthesis.* Thanks to your high-intensity training, sweating and insufficient zinc intake, athletes like you may have lower stores of zinc in the body —so supplementing is often necessary just to meet the basic zinc requirements, let alone optimal levels for peak performance.*
Magnesium helps regulate factors that are especially important for active individuals: protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation[1-3], just to name a few. It's required for energy production and contributes to the structural development of bone. When it comes to athletic performance, magnesium supports nerve impulse conduction, muscle contraction, and normal heart rhythm.*
