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. 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 Schänzer
(2007) found there was no substantial change in the serum total and serum free
testosterone over 7 weeks ZMA supplementation.
 Nader Moëzzi, 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 (Moëzzi, N, 2013).

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.
