Vitamin D3

Overview
Vitamin D3, also known as cholecalciferol, is one of the two main forms of vitamin D, with the other being vitamin D2 (ergocalciferol). Vitamin D3 is synthesized in the skin when it's exposed to sunlight, specifically UVB radiation. It can also be obtained from dietary sources like fatty fish, egg yolks, and fortified foods, as well as through supplements. Once in the body, vitamin D3 is converted into its active form, calcitriol, which plays a crucial role in regulating calcium and phosphorus absorption in the intestines and promoting healthy bone mineralization. Vitamin D3 supplements are commonly recommended to address deficiencies, support bone health, and bolster the immune system, making it a valuable nutrient for overall well-being.
