Sunlight enhances the transformation of provitamin D to vitamin D in the skin.

Sunlight enhances the transformation of provitamin D to vitamin D in the skin. Vitamin D is formed from two provitamins: Provitamin D3 (7-dehydrocholesterol) and animal provitamin D2 (ergosterol) of vegetable origin. Ultraviolet radiation from sunlight we receive in the skin, provitamin transform these into cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2) respectively. These are transformed in the liver to 25-hydroxycholecalciferol (or calcidiol) and then in the kidney is transformed through 1-25 dihydroxycholecalciferol (or calcitriol), which is the most active vitamin D product to facilitate intestinal absorption of calcium and phosphorus and bone resorption.

Sun exposure of about 10 minutes three or four days a week ensuring adequate levels of this vitamin in the body. Vitamin D produced in the skin is stored in adipose and muscle tissue from where it is used.

Moreover vitamin D as such from food. Are rich in vitamin D oily fish, fish liver oil, margarine, egg yolk, milk and dairy products.

The recommended daily amount of vitamin D is 5 mcg / day (400 U / day). This amount ensures proper bone development in children and adolescents. In adults over 50 years is recommended to increase their intake to 10-15 mg / day. There must be 25 mg / day in children or 50 mg / day in adults.

Vitamin D deficiency in the organism causes a decrease in calcium absorption by the intestine causing calcium levels decreased blood. Consequently, the parathyroid gland increases production of parathyroid hormone (PTH). This hormone acts upon the releasing bone calcium and phosphorus salts thereof (with the risk of demineralization), and stimulating kidney phosphorus loss through urine. This series of effects aim to try to normalize calcium levels in the blood, because as has been mentioned at the beginning, this cation is essential for the proper functioning of many body functions.

It is especially important to prevent calcium deficiency in children and the elderly. Therefore, in the first it is important that a balanced diet and frequent sun exposure. In older people is more common vitamin D deficiency in young adults, and is usually due to inadequate nutrition, decreased intestinal absorption of vitamin D and renal activation of pro vitamin, along with reduced exposure sun is very common.
