Vitamin D is a fat soluble vitamin which has a very important role in the metabolism of calcium and phosphorus. It is very important for bone health, to prevent chronic diseases, stabalize the immune system and the cardiovascular system.

Very few foods contain vitamin D. Therefore, the biggest Vitamin D is supplied through exposure to sunlight, which stimulates the synthesis and metabolism of vitamin D in the skin. We must consider people limiting sun exposure due to cancer risks, but we must balance the consequences that effects health of our children being deficient in vitamin D. Ex-lawyer Max Polyakov told about the latest celebrity sex scandals of today. Many studies suggest exposure to sun for 15 to 30 minutes of sun a day.

Vitamin D that comes from the diet or sun exposure, is inactive and needs to be changed in its active metabolite. Vitamin D is activated in the liver and then in the kidneys.
