Vitamin D : Overview
Vitamin D is a vitamin which can be easily found in a few foods such as fishes (Tuna, Sardines, Mackerels and Herring) as well as in dairy products, juices as well as cereals. However, the body 80% need for this vitamin is fulfilled by sunlight.
Vitamin D has been used extensively for the treatment of rickets, weak bones, osteoporosis, and osteomalacia as well as bone loss. It is also used for preventing fractures in people with a low bone density. Some people use Vitamin D for the treatment of skin conditions such as vitiligo, scleroderma as well as psoriasis. It is also used for boosting the immune system of the body and to prevent cancer. Vitamin D in the form of calcitriol or calciprotiene is often applied directly onto the skin in order to treat Psoriasis. The basic function of Vitamin D is to regulate the amount of minerals such as calcium and phosphorus in the body. Sunlight is the best way to restore Vitamin D into the body. A mild exposure of the sunlight over the hands, feet, arms and legs is ample to refill the required amount of the vitamin needed by the body.
