Optimum Nutrition ZMA, 90 capsules

Product information "Optimum Nutrition ZMA, 90 capsules"


The Optimum Nutriton ZMA capsules contain a combination of zinc, magnesium and vitamin B6. ZMA has been used in bodybuilding for many years due to its proven active ingredient formula. Zinc, vitamin B6 and magnesium contribute to normal energy metabolism. Zinc also contributes to the maintenance of normal testosterone levels in the blood and to normal protein synthesis.

Since athletes and active adults have greater nutritional needs than inactive people, ON's ZMA provides more than sufficient amounts of zinc, magnesium and vitamin B6. This novel zinc monomethionine aspartate formula can help fill in gaps in micronutrient intake.

  • Contains the PATENTED BLEND of zinc, magnesium and vitamin B6
  • May provide even better results when "stacked" with creatine, glutamine, HMB, or other strength and recovery products.

Take 1 capsule 30-60 minutes before going to bed.
