The body produces vitamin D in the skin after exposure to ultraviolet light — therefore, it is not technically a vitamin. Rather it is a fat-soluble steroid hormone, similar in structure to other hormones, such as testosterone and estrogen. Vitamin D, like other steroid hormones, can enter a cell’s nucleus and regulate numerous genes. Vitamin D serves as a major regulator of immune function and may play a particularly important role in preventing respiratory tract infections. In this clip, Dr. Roger Seheult explains how vitamin D is a misnomer and how it fulfills many critical roles in the body.
