ZMA is a nutritional formula composed of Zinc (as Zinc Monomethionine), Magnesium (as Magnesium Aspartate), and Vitamin B6 (as Pyridoxine Hydrochloride). The first benefit that ZMA can bring is to avoid deficiency in the supply of Zinc and Magnesium. Athletes typically have lower levels of Zinc and Magnesium, coupled with their typical metabolic functions in the body,
ZMA may have the potential to increase strength and muscle building. One study showed that ZMA combined with resistance training showed increases in testosterone, in IGF-1 (both anabolic hormones), and muscle strength. ZMA may help provide an adequate metabolism, able to respond to training and diet stimuli.
ZMA can help improve sleep quality, revitalizing the body after a day of work and/or training. It is recommended to take before sleeping. The regulation of the hours of rest directly stimulates muscle growth and the anabolic production of the hormone that helps the regeneration of tissues. Likewise, ZMA acts in the prevention of joint injuries and may help avoid cramps.
