Hi aarontshaffer,
Perhaps this will be of interest to you regarding the study from
Western Washington University:
http://www.usaswimming.org/USASWeb/ViewMiscArticle.aspx?TabId=339&Alias=Rainbow&Lang=en&mid=491&ItemId=1276
"ZMA (zinc monomethionine aspartate) - One ad touts: "This can make
you 2 ½ times the man you are!" The promotion of ZMA as a dietary
supplement for athletic performance is based on a single 1999 study
from Western Washington University. The results showed a 43% rise in
free testosterone levels in football players who used ZMA compared to
the ones who used a placebo. These same sites take aim at the theory
that athletes are deficient in both zinc and magnesium and therefore
need the supplement to improve their performance. What they neglect to
say is that athletes can improve their dietary intake of zinc and
magnesium by eating foods that are rich in these minerals and that
will also provide them with the energy-yielding nutrients that they
are also likely deficient in. What they also don?t tell you is that in
the study at Western Washington, the group that demonstrated the
increase in strength was much lower in strength to begin with than the
group whose strength increased to a lesser degree. One ad suggests
that to get the most out of your ZMA, use it in combination with (i.e.
?stacking?) Terrestris and Androstenediol (Prohibited!). Of course,
their ZMA is also the least expensive. Only one site mentioned that
taking ZMA can make you very sleepy. ZMA also contains Vitamin B6. One
brand contains 10.5 mg of Vitamin B6 per daily serving. This was 525%
of the RDA for males (2.0 mg/day). That value has changed, and the
current Dietary Reference Intake for Vitamin B6 for males and females
19-50 years of age is 1.3 mg/day, making 10.5 mg equal to 809% of the
daily requirement."
