Hi All. I buy zinc and magnesium separately from Walmart for about 2 bucks each, and take them at night instead of the ZMA biotest and other companies offer. Does anyone know what, if any, of the difference is? Is the extra Vitamin B-12 going to make any difference? Thanks!

I’d think you can do fine with these. The aspartate forms require fewer milligrams to achieve the same effect, but even forms like zinc oxide will work, just requiring more milligrams.
