Since ZMA contains minerals you might not be getting enough of anyway, and you definitely need, it seems to be a winning supplement. An important thing to note is that the zinc and magnesium must be in the aspartate form, not the chelate, sulfate, or citrate form commonly found in multivitamins. The ratio is also extremely important. There should be 11 mg of Vitamin B-6, 30 mg of the zinc monomethionine aspartate , and 450 mg of the magnesium aspartate per serving. (This is why you should just buy a ZMA supplement instead of individual magnesium and zinc supplements.) This supplement should never be taking with calcium, as calcium blocks absorption, and any ZMA that has calcium in it should be avoided. ZMA should also be taken before bed on an empty stomach.
Great article, well written and god conclusions of collected data.
How ever I am still curious if creating a “shortage” of sperm and decrease of testosterone by cycles of repeated ejaculations during a short period of time, maybe during the course of hours followed by “rest-days” if that over time would provoke the body to produce more Testosterone and sperm in a response to “progressive overload”.
Since this is the way the body handles a lot other things that challenges it´s system with everything from resistance-training, “repeated skin-abrasion”, bacteria and even some toxins.
