Vitamin D – An Effective Treatment for Insommnia
By: Dr. Gerard Guillory, MD
Vitamin D is sometimes referred to as “the sunshine vitamin” because our bodies synthesize vitamin D when our skin is exposed to ultraviolet rays from the sun. It is also categorized as a fat-soluble vitamin because it is found in a few fatty foods, including fish liver oil, beef liver, and egg yolks. More accurately, however, vitamin D should be categorized as a hormone. Vitamin D has activity in most cells of the human body. It increases our ability to absorb calcium, assists in fighting infections, and even improves mood.
