Vitamin D is produced in the skin via the UVb rays in sunlight. What is the most important to note is the amount of vitamin D that the body naturally produces with sunlight. Why is the daily recommended dose of vitamin D is 400 units when your body will make 10,000 units of D with full exposure in only 30 minutes.  Granted this amount is achieved when the sun is at it's highest point in the sky, you have to wonder what other roles this important nutrient plays in the body.

For decades, we only understood only one function of vitamin D, that it's necessary for calcium absorption. During the past few years, numerous studies have shown the correlation of vitamin levels with so many other functions in the body, including immune regulation, mineral absorption, mood regulation and much more. Low Vitamin D is thought to have implications in cancer, diabetes, heart disease, rheumatoid arthritis, multiple sclerosis and many other debilitating conditions.
