Vitamin D is one of those essential substances that we cannot function well without. It is common knowledge that the body makes its own Vitamin D when the skin is exposed to sunlight. It is that form that we use most efficiently. While Vitamin D supplements are great, “homemade” is better. That is not a “free gift” to go into the sun at great lengths. Small amounts are necessary; too much is not good (that is another story).
Vitamin D plays a role in many body systems. We need it to help with calcium absorption, it is considered by many to be protective against some cancers, helps regulate blood pressure and glucose metabolism. Therefore is essential in the management of diseases like high blood pressure and diabetes. Again, this is not saying that Vitamin D treats any of these issues but it is essential to maintenance and restoration of health.
