As many of you know, summer time means summer tans. What exactly is your body doing when you lay out in the sun for hours though? Research shows that the sun is not only turning your skin to leather, but actually initializing the release of vitamin D3 on the skin. Our bodies naturally need a healthy level of vitamin D in order to maintain strong bones. We normally get this from various foods we eat or supplements. The key to this research is the Sun's contribution to vitamin D in our bodies.
Many people believe the Sun "creates" vitamin D when it really causes the skin to release it as vitamin D3. This vitamin moves through our bodies to reach the liver where it produces calcitriol. The new molecule is the active form of the vitamin that leads to stronger bones. Without it, we would all suffer from osteoporosis and be brittle. Now this leads us to question how much Sun is enough to release a healthy amount of vitamin D from the skin?
