If Zinc and Magnesium intake is adequate through dietary sources, how does ZMA produce any results? I would expect that Scott's experience would be pretty common place when switching from a diet that was likely deficient in both of these minerals to one that was rich in them. Also, wouldn't the extra magnesium compromise calcium absorbption?

I'd also like to note that in the primary study done on ZMA, which was performed at WWU (where I went to school), the athletes pre-trial levels of zinc and magnesium were close to deficient, which would explain how ZMA might have boosted their performance. Also, the study was funded by ZMA patent holders (SNAC Systems inc.), and one of the study's authors has significant equity in that company.
