Vitamin D-3 400 IU 100 Softgels
Vitamin D (as cholecalciferol) is a fat-soluble vitamin. It is known as "solar", as it is formed in the body by the action of the sun's UV rays on the skin. Vitamin D is converted in the kidneys into the hormone calcitriol, which in practice is its most powerful form. The effects of this hormone are directed to the intestine and the bone.
