“Vitamin D is a pre-pro hormone it's not active at all vitamin D is converted in the liver first step to a compound called 25 hydroxy vitamin D that is a pro hormone it also is inactive it has no activity whatsoever from there 25 hydroxy vitamin D can be metabolized one of two ways it can either be one alpha hydroxylated in the kidney to the active form one alpha one uh 25 dihydroxy vitamin D which will then do all of the business of vitamin D such as calcium absorption from the gut suppression of the immune system at the toll like receptor 4.”
