Vitamin D comes from exposure to sunlight.

Vitamin D deficiency may be secondary to multiple etiologies including decreased dietary intake or absorption, reduced exposure to sun, increased hepatic catabolism, decreased endogenous synthesis, and end-organ resistance. Vitamin D deficiency has also been linked to the pathogenesis of osteoporosis and hip fractures as well as other skeletal and non-skeletal disorders.
