Brilla further explained, "The muscle strength increases may have been mediated by the anabolic hormone increases in the ZMA group. The ZMA group had 30% increases in free and total testosterone levels compared to 10 percent decreases in the placebo group ... The ZMA group also had a slight increase in insulin -like growth factor-1 (IGF-1) levels compared to a 20 percent decrease in the placebo group. This study shows that anabolic hormone and muscle strength increases can be induced in already strength-trained athletes by using a novel zinc-magnesium preparation."
ZMA is a scientifically developed anabolic formula containing the most important vitamins and minerals, such as: zinc, magnesium, vitamin B6, which effectively support body functioning. Magnesium encourages appropriate muscle and nerve activity, helping to reduce the feeling of tiredness and fatigue and maintain normal energy metabolism. A complex of magnesium and zinc helps to ensure correct protein synthesis. Zinc is essential to maintain the correct level of testosterone in the blood helping to ensure normal fertility and reproductive function. Additionally, it helps to achieve the proper functioning of the immune system and protects cells against oxidative stress. Vitamin B6 contributes to the regulation of hormonal activity and aids in the production of normal red blood cells.
