Now some of you might wonder: "Hey John, l am not taking a Calcium supplement, so l don't have any problem with that", but the truth is, that ALL the whey, soy or milk proteins on the market contain at least 100-200mg per serving, and if you mix them with milk, then the amount is more or less 500mg! So if most of you are like me, drinking the last protein shake meal of the day just before you go to sleep, forget taking your ZMA.
How does this apply to taking a multi with postworkout shake along with a calcium supp???
