I was aware of the synthesis of Cholcalciferol into calcidiol and then in turn into calcitriol but the terms active and inactive would refer to its utilization by the body but I have not really pondered that way of looking at it.
I would beg to differ on Ozone being the safest and most effective cancer therapy and where in my experience and research the Budwig protocol would be equally as effective. As you mention, lifestyle and dietary changes are paramount, but the Gerson & Oleander approaches are also vitally important.
I also believe that a comprehensive treatment plan would be more effective as long as they are compatible and work in unison as you have also mentioned.
I expect you will list these bogus and unproven cancer therapies in your book, but perhaps you would be good enough to provide a tidbit of info as to what some of them are.?
