ZMA has been a popular weapon in the arsenal of those seeking to gain muscle mass and improve recovery time from intense workouts. ZMA is the simple combination of the minerals zinc and magnesium, along with Vitamin B6. Supplementing with ZMA promotes a more restful sleep and aids in hastening the muscle recovery process, as well as helping to promote greater testosterone levels for more muscle mass.

Other formulas have combined additional ingredients such as valerian root, melatonin or tribulus terrestris to aid in rest and relaxation or to promote greater testosterone production. Either way, ZMA supplements are an inexpensive and effective way to enhance your training regimen.
