From The Manufacturer

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.
