My D3 was initially prescribed by an Oncologist after bone DEXA Scan that showed good density..
No D3 level was checked then in my blood.
I was told to take it due to the hormone tablets from cancer...
6 months later my gastroenterologist does D3 and calcium test and although thankfully they are in sync my D3 was really high... greater than 150.
Despite stopping D3 supplements at that stage my levels are still that high!!so now have had to stop eating food with extra D3 added in to it...
Please, everybody do not just start taking D3 from the media saying we should.. please ask your GP to do a d3 and calcium test first..
High D3 is dangerous too.
