Vitamin D Supplements and SAD

Seasonal Affective disorder affects many people. This problem involves people feeling depressed in the winter months, and it usually hits people who live in areas where daytime is shorter in that part of the year. Thus one known cause of SAD is a lack of natural sunlight...but until recently it was not known why this caused people to feel depressed and lethargic. Recently, however, it has been hypothesized that it is a lack of vitamin D, which our body produces when we are in the sun but we otherwise get little of in a normal diet, that causes this problem. Vitamin D supplements can be the cure...more later, or see www.dsupplements.com.
