Taking Vitamin D supplements has been shown to reduce the risk of death from any cause. There has been a wide range of studies showing that a vitamin D deficiency is associated with a cross section of diseases, including cancer, heart disease and diabetes.
The human body makes vitamin D from sunshine. You would think that it would be easy to get enough, but people don't go outside as much, and when they do they are warned to cover up and wear sunscreen. The truth is that only a moderate amount of sun exposure is needed to create healthy levels of vitamin d. In sunny climates and season, less then a half hour is needed.
You can also get vitamin D from certain foods, but not in any high quantity. If getting more sun isn't going to work for you, one of the best way to elevate your levels would be to take a supplement. It is a relatively low cost method to keep you from getting serious ill.
