What is the hydroxylated form of vitamin D?

The human body requires a sophisticated multi-step process to activate vitamin D before it can be used, and this process is known as hydroxylation. A biologically inactive precursor, whether produced from sunlight or consumed from food, must undergo two hydroxylation reactions in the liver and kidneys to become its potent, active form. This vital conversion is what allows vitamin D to regulate key bodily functions, particularly calcium and phosphate absorption.
