Optimum Nutrition ZMA contains the patented blend of zinc, magnesium, and vitamin B6. Two recent clinical trials have shown that a synergistic combination of Zinc Monomethionine Aspartate, Magnesium Aspartate, and Vitamin B6 can significantly increase anabolic hormone levels and muscle strength in well-trained athletes. The novel Zinc Monomethionine Aspartate formula may also help to increase endurance, healing, growth and restful sleep. This product may offer even better results when "stacked" with Creatine, Glutamine, HMB, or other strength & recovery products.
