Most of us are familiar with Vitamin D. Although there are other sources, vitamin D comes mainly from the sun. It develops naturally in some foods, such as fish, fish liver oils, and egg yolks.
Too much time spent indoors plus poor nutrition have driven a rise in vitamin D deficiency in people in the past two decades. But what are the symptoms of a deficiency, and how can it be prevented?
The symptoms of vitamin D deficiency can be vague, may change over time, and are similar to symptoms of a wide range of ailments. Hence, it is dangerous to self-diagnose a vitamin D deficiency.
People who experience symptoms of vitamin D deficiency, or who have unexplained illnesses or nutritional deficiencies, should request a test for vitamin D deficiency.
According to the Centers for Disease Control and Protection (CDC), about a quarter of the population is at risk for vitamin D “inadequacy.” A simple blood test can detect if this becomes vitamin D deficiency.
