Vitamin D3

What Is Vitamin D3?

Vitamin D3, scientifically known as cholecalciferol, is a fat-soluble vitamin that functions more like a steroid hormone in the human body. It is primarily synthesized endogenously when the skin is exposed to ultraviolet B (UVB) rays from sunlight, which converts cutaneous 7-dehydrocholesterol into previtamin D3 and subsequently into vitamin D3. Additionally, it can be obtained exogenously through dietary sources, predominantly animal-based foods such as fatty fish (e.g., salmon, sardines), egg yolks, and cod liver oil, as well as through fortified foods and dietary supplements.
