Kidneys, skin, liver are the organs involved in vitamin d production. The body's primary source of vitamin D is the epidermis.
The active form of vitamin D, 1,25-dihydroxyvitamin D (calcitriol), is produced by the skin, liver, and kidneys and aids in preserving healthy levels of calcium and phosphorus in the blood. When exposed to ultraviolet light from the sun, a cholesterol-derived molecule in the skin is transformed into vitamin D. The sun's rays have been producing vitamin D on this planet for more than 500 million years. When exposed to sunshine, skin's 7-dehydrocholesterol absorbs UV B rays and transforms into previtamin D3, which isomerizes into vitamin D.
