About Optimum Nutrition ZMA

It's not how much sleep, but the quality of sleep, that separates high-level competitors from their recreational counterparts. And you can bet your next paycheck that they're getting 'champion' sleep by supplementing with ZMA.

ON ZMA is a mixture of Zinc, Magnesium Aspartate, and Vitamin B6. Nothing outrageous, but extremely effective. Research shows ZMA to have a positive effect on sleep, endurance, and muscle growth - all of which a budding athlete needs.

  • PATENTED Combination of Zinc, Magnesium, & Vitamin B6
  • ATHLETES May See a Testosterone Boost
  • STACK With Other Strength & Recovery Enhancing Supplements

Directions Optimum Nutrition ZMA Recommended Use

For more restful sleep and increased endurance, take one capsule of ZMA per day. Take ZMA about an hour before sleep on an empty stomach.
