Vitamin D is the only vitamin whose biologically active form is hormone. For healthy children and adults, exposing the hands, face and arms on a clear summer day for 10-15 minutes several times each week provides adequate vitamin D. the main function of vitamin D is bone metabolism and calcium homeostasis.
Foods with Vitamin D
Canned pink salmon, canned tuna, cod liver oil, sunshine, eggs, vitamin D-fortified milk, fortified orange juice, fortified cereal, fortified margarine, sardines, and fish roe, Brief and casual exposure to sunlight can be safely encouraged. Sunlight and vitamin D exposure tend to be low in northern during winter months.
Absorption, metabolism and excretion of Vitamin D
Two forms of vitamin D are metabolically active. Vitamin D2, ergocalciferol, is is formed when ergosterol in plants is eradicated by ultraviolet light or sunlight. Vitamin D3 is formed when 7-dehydrocholesterol in the skin of animals or humans is eradicated by ultraviolet light or sunlight.
Both forms are absorbed in to the blood,. About 50% of dietary vitamin D is absorbed, most rapidly in the duodenum but the greatest amount in the distal small intestine. Like other fat soluble vitamins, it is transported in the blood bound to protein. The liver alters the vitamin to calcidiol; an inactive form of vitamin D. by enzyme action, the kidney converts the calcitriol, the active form of vitamin.
Functions of vitamin D
Calcium metabolism
The principal function of vitamin D is to regulate calcium levels in the blood and tissues. A fall in blood calcium will trigger production of active vitamin D, which stimulates calcium absorption from the diet, increases release of calcium from bones, and slows renal excretion.
Skeletal health
Vitamin D is essential for normal bone growth during childhood and for maintaining bone density and strength during adulthood. Vitamin D enhances calcium absorption from foods and increase calcium and mineral deposition in to skeleton.
Cell growth and development
Vitamin D is an important regulator of cell development throughout the body, particularly in the white blood cells and epithelial cells.
Immune system
Vitamin D enhances the activity and responses of white blood cells in infections.

Use of Vitamin D in prevention and therapy
Bone disorder
Vitamin D is effective at treating rickets in children. Together with calcium, it can slow or prevent bone loss in individuals at risk of osteoporosis and reduce the fracture rate in individuals with osteoporosis.
Psoriasis
Vitamin D due to its ability to regulate epithelial cell growth and development can reduce the hyperproliferation of skin cells in psoriasis and may reduce the severity of the disease.
Hearing disorder
In certain individuals’ vitamin D, together with calcium, can reduce symptoms of tinnitus and improve hearing loss.
Immunity
Vitamin D can stimulate white blood cells and may enhance resistance to the infection
Cancer prevention
Ample intake of vitamin D may reduce the risk of colorectal and breast cancer.
