Vitamin D is a fat soluble vitamin that is essential for the absorption of calcium and phosphorus. Several forms of vitamin D exist but the most important form is Vitamin D3. While there is a lot of research on vitamin D the most conclusive finding is its benefit to bone health.
Vitamin D can be produced naturally from sunlight exposure as the UV rays induce the body to manufacture Vitamin D from cholesterol. The amount of sunlight needed ranges from about 5 to 20 minutes 2 times per week.
