I actually just bought Dr. Mark Sircus's book "Transdermal Magnesium Therapy" and I am going to try Ancient Minerals magnesium chloride bath crystals as a spray. Yeah, I quit calcium. Also, I think they are recommending that vitamin D should be in the 50-70 range on a blood test so the 10,000 IU is not really much at all. Hard to hit toxicity. Again, there are some interesting books that discuss vitamin D that helped me understand it better. I found I feel really great on the covid protocol and will continue with everything but cut the Ivermectin down to once a week. This is all my opinion...I am NOT a doctor and would suggest you do your own study.
