The Vitamin you take from sun?
Vitamin D is formed in your skin when the skin is exposed to UV
Sunscreen, Vitamin D and Calcium
Why do so many people lack vitamin D? Vitamin D is not found in聽very many foods and when it is in low quantities. Your body creates vitamin D but you must expose your body to the sun. The long you stay in the sun the more vitamin D you produce. But, you can also get vitamin D from supplements and some foods that are fortified with vitamin D
When UV light from the hits your skin, fatty acids or cholesterol in your skin are activated to create vitamin D and Inositol triphosphate, INSP-3. In 5 to 10 minute skin exposure to the sun, 20,000 units of vitamin D are created. This vitamin D quickly finds it way into your intestinal walls where it helps to pull calcium through its walls and into your blood stream. No matter how much calcium food you eat or calcium supplements you take, your will not absorb the calcium your body needs without a large supply of vitamin D.
Sun Screen and Vitamin D
With the hot days of summer, many people use sunscreen thinking they are doing something good for themselves. Most sunscreen is designed blocks UVB sun radiation, which allows your body to create Vitamin D. Some times they do not provide the block for the UVA radiation, which is responsible for sunburn and skin cancer. When you do need a good sunscreen make sure it blocks both UVB and UVA, since both UVA and UVB cause tanning and burning.
