Summary of ZMA

Primary information, health benefits, side effects, usage, and other important details

ZMA is a patented formulation, which contains zinc, magnesium, and vitamin B6.

It is claimed to increase testosterone levels, but there is no evidence to suggest that this occurs in healthy men. Though men with zinc deficiencies can supplement zinc to fix their deficiency and increase their testosterone levels, there is no evidence to suggest this occurs in men with no deficiency.

Aspartate has also been claimed to increase testosterone, but it is in too low of a dose in ZMA to have any effect on testosterone.

Despite ZMA’s lack of effect on testosterone levels, it can be a useful supplement for people that lack zinc and magnesium.
