Vitamin D

Humans receive vitamin D, or cholecalciferol, from fish and dairy products. Vitamin D production in the human body happens when skin gets exposed to sunlight. However, most vitamin D consumed in America comes from fortified foods. The food industry provides vitamin D supplementation to support a wide range of bodily functions. D Vitamins are used to fortify pharmaceutical and food products and are used topically in skin care.
