I'm so on the fence about calcium, First it "helps prevent the candida growth that magnesium causes in a study", then elsewhere we read that calcium aggravates biofilm (presumably this includes yeast biofilm). I'd read both theories awhile back, and since then have been worried about whether to take calcium or not.
Here's another study, and if I'm reading it right I think it says that EDTA chelates calcium out of biofilms, thus weakening the biofilm: (EDTA is easy to buy from various online vitamin supplement websites).
Whatever you decide to ask your professor, good luck and please tell us what you end up learning!
