50k iu of Vit D is potentially toxic on its own. There was an ‘Ivory dome’ theory going round a few years ago about the potential of Vit D, Vit K2 & magnesium oil as a treatment though.
> No ! Wrong ! 50 kui vit D is totally safe to use. A lot of people ( me including) are on 70kUI/weeks for years without any issues ( blood test, livers ok) btw, some people do the Coimbra protocol with 200KUI / DAY ( Yes, 200 000Ui/DAY). 50kui weeks is totally safe.
