ZMA+Calcium

[atmilner]

I've been reading up on zinc and magnesium etc, so i got a calcium magnesium and zinc supplement. That was before I read anything about calcium interfering with zinc blah blah blah. I know when to take zinc and magnesium and why u take it then but since I have already bought this supplement I'm gonna take it anyways, even though it has calcium.

My question is, why do u think there would be a product with this combination of minerals if calcium interferes so much with the absorption of zinc? If its really that important, even for people who dont work out or are athletes, it seems like the supplement companies wouldn't make this item.
