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. Benefits: An essential nutrient for healthy bones A deficiency is associated with increased risk of hip fracture Promotes good joint function Vitamin D deficiency causes rachitis Important for a healthy immune system Supports healthy skin The major biologic function of vitamin D is to maintain normal levels of calcium and phosphorus in the blood. It helps in the absorption of calcium, encouraging the formation and maintenance of healthy bones. Increases bone mineralization in combination with several other vitamins, minerals, and hormones. Without vitamin D, bones can become thin, brittle, soft and shapeless. This feature prevents skeletal diseases such as rickets in children and osteomalacia in adults which cause defects and weaken bones.
