Optimum Nutrition ZMA 90 Capsules | Zinc, Magnesium, & Vitamin B6

ZMA is a natural mineral supplement made of zinc, magnesium, and vitamin B6. ZMA supports the immune system as well as muscles and plays a role in metabolism and muscle health. It may also play a beneficial role in sleep.

Does ZMA Boost Testosterone?

There is research which claims ZMA may help maintain a higher level of testosterone during longer bouts of exercise and during intense training. 

Will ZMA Make You Sleepy?

ZMA is not a sleep formula and should not make you drowsy. That said many people do use ZMA to help with sleep and relaxation as two of the minerals are known to promote calm and sleep, and Vitamin B6 is a precursor to melatonin. ZMA is more of a sports performance supplement than it is a sleep supplement. 

What Does ZMA Stand For?

ZMA stands for zinc monomethionine aspartate, magnesium aspartate, and vitamin B6. This supplement is often used by bodybuilders, powerlifters, gymnasts and other high level athletes. 


Take 3 capsules, before bed. Women: Take 2 capsules, before bed.
