Zinc plays an important role in testosterone synthesis. Magnesium is an important component of creatine kinase in muscle. Studies have shown that supplementation of 30 mg zinc and 450 mg magnesium every day can increase testosterone levels by 30%. Magnesium also helps to calm the human body and help sleep.

Any bodybuilder and athlete who wants to strengthen his strength, improve his performance and increase his muscles should consider supplementing ZMA. Many studies show that most athletes lack zinc, magnesium and vitamin B6. Previous studies have tested the effect of zinc loss in muscle on muscle function, and proved that the endurance or overall strength of muscle will drop sharply when zinc is seriously deficient. The degree of decline is related to the decrease of zinc concentration in plasma.
