ZMA

ZMA is the combination of the minerals zinc and magnesium, along with Vitamin B6, that were designed to increase free testosterone levels in the body and improve muscle recovery time. Zinc is necessary in the production of testosterone, while magnesium has mild sedative effects on the body. Taking ZMA supplements before bed promotes a deeper, more restful sleep, in which anabolic hormone production is at its highest.

By supplementing with ZMA, users may increase muscle mass and strength, while simultaneously reducing muscle recovery time and soreness.
