Guest guest Posted July 31, 2002 Report Share Posted July 31, 2002 ZMA is designed to be taken last thing at night on an empty stomach in order to optimise the absorbs ion, it is base on research which shows that hard training can deplete zinc and magnesium levels which can in turn lead to lower testosterone and insulin growth factor levels. By supplementing zinc and magnesium it has been shown that it is possible to maintain higher Insulin Growth Factor and Testosterone levels during periods of hard training. Zinc and magnesium levels are often shown to be low in athletic populations. Bill Quote Link to comment Share on other sites More sharing options...
