???? ZMA has mag aspertate but all I have read says mag. glycinate is the best kind to take. Do you think it is possible the mag. asp. reacts differently with the zinc than the mag. gly would? And then we add in the B6. I question if they use aspertate because it is cheaper or because it is better for this combo. If cheaper is the thought then do you think the same benefit could be had by taking mag. glyc., zinc and b6 at bedtime? I knew I should have paid more attention in chem class.
