What Do You Know About Sunscreen Vitamin D and Calcium?
So why do so many people lack vitamin D? Vitamin D is not found in very many foods and when it is in low quantities. You should get most of the vitamin D your body needs from the Sun. But you can also get it from supplements and some foods that are fortified with vitamin D
When the sun’s UV light hits your skin, fatty acids or cholesterol in your skin 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 finds it way into your intestinal wall where it assists calcium to move 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.
