Explanation: 

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. Previtamin D3 can either isomerize to vitamin D3 or be photolyzed to lymisterol and tachysterol.

Detailed explanation-2: -Another study found that 30 minutes of midday summer sun exposure in Oslo, Norway was equivalent to consuming 10, 000–20, 000 IU of vitamin D ( 8 ). The commonly recommended daily dose of vitamin D is 600 IU (15 mcg) ( 3 ).

Detailed explanation-3: -The major biological function of vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones.
