ZMA WorksZMA is a scientifically designed anabolic mineral formula containing zinc monomethionine aspartate, magnesium aspartate and vitamin B-6. Studies have shown that it has a clinical effect on testosterone levels when taken in a combination containing 30 mg of zinc and 450 mg of magnesium per day. The most famous study conducted by Lorrie Brilla at Western Washington University indicated that this combination could raise testosterone levels by as much as 30%. To get the benefits this supplement can offer, it is of great importance to take it when there is no calcium in the stomach (not with milk or whey protein). The best time is within an hour of your bedtime. The scientific evidenceThe most talked about study is the following. Lorrie Brilla, PhD, a sports performance researcher at Western Washington University, recently reported that ZMA significantly increase free testosterone levels and muscle strength in NCAA football players. The study results were presented by Dr. Brilla on June 2, 1999, at the 46th Annual Meeting of the American College of Sports Medicine in Seattle, WA, and were published in the official ACSM journal, Medicine and Science in Sports and Exercise, Vol. 31, No. 5, May 1999.Specifically, Brilla reported that "a group of competitive NCAA football players who took ZMA nightly during an eight-week spring training program had 2.5 times greater muscle strength gains than a placebo group. Pre and post leg strength measurements were made using a Biodex isokinetic dynamometer." The strength of the supplement group increased by 11.6% compared to only a 4.6% increase in the placebo group. Brilla further explained, "The muscle strength increases may have been mediated by the anabolic hormone increases in the supplement group. The supplement group had 30% increases in free and total testosterone levels compared to 10 percent decreases in the placebo group... The supplement 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." Many other studies have shown the same results! No wonder bodybuilders around the world are seeing better gains than ever before. No question about it, this supplement has the scientific research and real-world anecdotal evidence to launch it to a level previously held only by creatine.
