Optimum Nutrition ZMA (90 Caps)

Optimum Nutrition's ZMA blend combines Zinc, Magnesium and the vitamin B6. This clinically proven combination of ingredients has been shown to promote improved muscle recovery and mass gain, help regulate your sleep and support your immune system - while it might not a be a wonder drug, its close!

At the extreme, some tests have shown a tremendous 30% increase in testosterone, which when combined with a well-planned diet and workout regime means ZMA can help you make seriously good gains. Since many of us don’t get the required amount of magnesium or zinc in our diet, the results from ZMA can be extremely pronounced!


  • Boosted Testosterone - Optimum ZMA tops up your zinc supply and has been shown to promote an increase in testosterone production by as much as 30%! When combined with a planned workout routine, that massive gain results in increased muscle mass and strength.
  • Better Sleep, Better Recovery - Magnesium can really improve the quality of your sleep; it does this by regulated your stage 3 and stage 4 slow-wave sleep. In turn, better sleep means faster recovery!
  • Immune System Care - Zinc provides support for your immune system, especially important when you’re dealing with post-workout fatigue
  • Healthy Cortisol Balance - Both magnesium and zinc are reported to reduce cortisol build up, reducing stress both mentally and physically in the body.

Who is Optimum ZMA For?

Because Optimum ZMA is such a versatile product it can be a beneficial supplement for a wide range of people. If you want to build mass, the testosterone increase can make pronounced improvements to your body composition and muscle size.

For any athlete, better quality sleep is not only desirable for better recovery, but general health and well-being too. It’s hard to oversell the benefits of ZMA!
