ombowstring..I understand your interest in Biotech..Has peaked your interest in the only drug available for Hyperparathyroidism..I think it’s in Japan..Based upon Certain Vit D actions..!!!
However I have NO experience with it..Vit D in my experience and knowledge..Helps absorb Calcium from the intestine..I am NOT AWARE of the mechanism of action of this Japanese Drug..ie..How it lowers serum Calcium..!!!
Sorry..My knowledge is Deficient for this mechanism of lowering of Serum Calcium..by the use of Vit D supplementation..!!!
Ombowstring ... Vit D3 makes us to absorb more calcium to our system , and we need Vit K2 to direct this calcium to go to our bone and teeth and not our arteries and heart ..
It is a very interesting and important Vitamin .. Also play a role in cancers ..,
