GENERAL HISTOLOGY

Detailed explanation-1: -The skin is responsible for producing vitamin D. During exposure to sunlight, ultraviolet radiation penetrates into the epidermis and photolyzes provitamin D3 to previtamin D3.

Detailed explanation-2: -Impact of melanin on vitamin D production and synthesis The less melanin, the lighter the skin. The amount of melanin in the skin affects vitamin D status because the skin depends on UV rays to synthesize vitamin D, and darker skin inhibits its production.

Detailed explanation-3: -When your skin is exposed to sunlight, it manufactures vitamin D. The sun’s ultraviolet B (UVB) rays interact with a protein called 7-DHC in the skin, converting it into vitamin D3, the active form of vitamin D.
