ZMA (Zinc Monomethionine Aspartate, Magnesium Aspartate and Vitamin B6) is a supplement used primarily by athletes, gymnasts, and bodybuilders. It is most often used as a recovery aid; notably, studies show that ZMA helps the body achieve deeper levels of REM sleep. It was developed by Victor Conte (founder of BALCO Laboratories in Burlingame, California). ZMA claims to raise strength levels and may enhance hormonal profiles. The study most often used to support the hormone effects of ZMA is one done at Western Washington University. Dr. Lorrie Brilla (and a ZMA supplement manufacturer) studied 12 NCAA division II football players who took ZMA nightly during an eight-week spring training program and a separate group assigned a placebo pill. The athletes taking the ZMA had 2.5 times greater muscle strength gains than the placebo group; the ZMA group increased by 11.6 percent compared to only 4.6 percent in the placebo group. The ZMA group also had 30 percent increases in testosterone levels (compared to 10 percent in the placebo group). However, one of the scientists who conducted the study holds the registered trademark for the original formula of ZMA, and his company funded the research.
