I've mentioned this before, but my wife is a parathyroid surgeon (parathyroids are the glands that regulate the calcium in your neck) and would beg you to PLEASE monitor your calcium levels if you are supplementing with Vitamin D. She often sees patients on high doses of Vitamin D from well intentioned doctors, but with out of whack calcium levels because of it, and the patients can be very sick without understanding why. Often their doctors don't understand the processes either which is why they end up with her. I'll have her write a blog post about it at some point, but it is a real risk with possible severe long term consequences and she sees it a lot more often these days. She is getting her blog kicked off here (just yesterday actually) https://devaboone.com if you want to follow along.
