No this is not one of those post about how much Protien do I need to take to get big? This is my situation. My doctor has perscribed me a medication that I have to take twice a day but I can't have it with milk or calcium one hour before and two hours after or it will greatly reduce the effectivness of the drug. Does protien powder have calcium in it? If it does I'm screwed cause there is no way I will be able to eat my regular diet (5 -6 meals a day) The label on the container dosen't list that type of information. Just the protien, carbs, fat and the protein profile. Just thought someone might be able to help me out. Thanks!
