Looking for ZMA supplements? Looking for a supplement to help boost your testosterone levels?

ZMA supplements are typically made using Zinc Monomethionine Aspartate, Magnesium Aspartate and Vitamin B6.

ZMA should be taken on an empty stomach 30 - 60 minutes prior to bedtime to help synchronise absorption with sleep. ZMA should not be taken with foods or supplements containing calcium because calcium blocks the absorption of zinc.

A 1998 study was undertaken on NCAA football players during an 8-week spring training program. The control group was told to cease taking any nutritional supplements. Those who took the ZMA tablets claimed greater increases in muscle strength.
