Natural Testosterone Boost

Natural Testosterone Boost

A new, all-natural combination of essential minerals and vitamins is showing promise for athletic enhancement. In one study, a formula containing zinc I-monomethionine, zinc/magnesium asparate and vitamin B6 (patented as ZMA) increased total testosterone levels 32.4 percent, while placebo levels decreased 10.5 percent. The formula also improved sleep efficiency, which, in turn, enhanced muscle recovery.
