About this ingredient
Vitamin D is a fat-soluble vitamin that plays an essential role in calcium and phosphorus metabolism, helping maintain healthy bones and teeth. It also contributes to normal muscle function and supports the proper functioning of the immune system.
Vitamin D can be produced by the body when skin is exposed to sunlight and can also be obtained from foods and dietary supplements. Common supplemental forms include Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D3 is commonly used in nutritional supplements.
Adequate Vitamin D intake is particularly important for maintaining normal calcium absorption and healthy skeletal function. Dietary sources include fatty fish, egg yolks, fortified dairy products, and fortified foods.
