ZMA is a potent combination of zinc, magnesium, and vitamin B6 that has
been shown to increase muscle strength, size, and recovery when used in
conjunction with intense weight training. Optimum Nutrition's ZMA may
help you sleep better too, both thanks to its blend of active
ingredients and because of the peace of mind you gain from knowing that
Optimum Nutrition uses only SNAC System, Inc. ZMA, the zinc-magnesium
formula supported by published research.
