I was running out of ZMA, and wandering down the supp row at my local market, and saw they had a buy one get one free sale on a zinc/magnesium supp. So, being the economical college student that I am, I decided to buy two to use when my ZMA ran out.
Problem is, it has calcium too. 1000mg calcium, 400mg magnesium, 15mg zinc per serving. Now, I saw on some old threads that calcium gets in the way of absorbance of other minerals. If I take this pre-bed, will I eventually digest the zinc and magnesium while sleeping, or am I essentially just peeing my money into the toilet?
