Optimum Nutrition ZMA 60 Servings 180 Capsules

There is no doubt that we are all lacking in Zinc & Magnesium levels but before you go out and buy some synthetic product from your corner drug store. You may want to know that those kind of products have horrible absorption rates! So why not supplement with Zinc & Magnesium your body recognizes & can actually use! The synergistic combination of Zinc Monomethionine Aspartate, Magnesium Aspartate & Vitamin B6 have proven in clinical studies to increase probolic hormone levels! And may increase endurance, healing, growth & while promoting restful sleep!

  • Contains Patented Blend Studied In Clinical Settings

  • Even Better Results When Stacked With Creatine, HMB, Or Other Products!

    Great sleep and recovery aid

    ZMA is a great product to add to your stack - it helps improve restful sleep, many people are deficient in magnesium, and zinc may improve immune system response. I like ON's because they're a large-scale company that does their own manufacturing.

    Great product

    I've been having great sleeps since using ZMA. Wicked dreams and wake up with a much clearer mind.

    Great product
