14. 14. ERGOGENIC AID REVIEW Zinc Magnesium Aspartate (ZMA) Zinc magnesium aspartate (ZMA) is a supplement used vastly in the bodybuilding and fitness world for potential recovery benefits (Taylor, L, 2004). Potential to increase anabolic hormones, lean body mass and overall training adaptations.
15. 15. ERGOGENIC AID REVIEW POSITIVES Colin D. Wilborn, Chad M. Kerksick and Bill I. Campbell (2004) found that ZMA supplementation increased serum zinc levels by 12-17% and caused a slight increase in magnesium levels over a period of 8 weeks in test subjects when coupled with resistance training. No significant clinical side effects were found that can be directly attributable to ZMA supplementation. NEGATIVES Multiple studies including K Koehler, M K Parr, H Geyer, J Mester and W Schnzer (2007) found there was no substantial change in the serum total and serum free testosterone over 7 weeks ZMA supplementation. Nader Mozzi, Maghsoud Peeri and Hasan Matin Homaei (2013) showed that ZMA supplementation coupled with resistance training lead to an 11.42% and 21.36% increase respectively in free and total testosterone than initial levels, while the levels of these hormones in the placebo group has shown 6.48% and 21.15% increases, respectively (Mozzi, N, 2013).
16. 16. ERGOGENIC AID REVIEW PERSONAL OPINION Can potentially slightly increase levels of zinc and magnesium in the body. Based on peer reviewed literature it has little to no effect on muscle mass, strength adaptations, testosterone and other anabolic hormones in the body when coupled with resistance training. Therefore the efficacy of ZMA is not applicable in this instance and thus the consumption not necessary.
