Abstract Vitamin D3 is a prohormone that is essential for calcium homeostasis. It is naturally produced in the skin by ultraviolet‐B (UVB) irradiation of 7‐dehydrocholesterol. In the absence of skin production, vitamin D3 can also be obtained fro

Human studies have shown that individuals with colon cancer tend to have lower serum 25-hydroxy-vitamin D3 [25(OH)D3] levels compared with healthy controls, but whether this link is causative, a result of the disease or an indicator of another factor

The primary source of vitamin D3 for humans is that produced in skin by ultraviolet irradiation. Ultraviolet (UV) B (UVB, 280-310 nm) light causes the isomerization of 7-dehydrocholesterol (7-DHC) to pre-vitamin D3 that is thermally isomerized to vit

Vitamin D is produced in the skin following exposure to sunlight. Ultraviolet (UV) B (UVB, 280–310 nm) results in isomerization of 7-dehydrocholesterol to previtamin D that spontaneously isomerizes to vitamin D. This pool of skin-derived vitamin D
