Recognizing the Signs of a Vitamin D Deficiency

Often referred to as the “sunshine vitamin,” vitamin D is produced by the body in response to exposure to the sun’s ultraviolet B (UVB) rays. Vitamin D is also found in a few animal-based foods, such as egg yolks, some types of fish, beef liver, and fortified milk. A building block of strong bones, this essential nutrient helps the body absorb dietary calcium and is also needed for several other vital bodily functions.

Despite this, many people underestimate the importance of vitamin D, and studies show that approximately one-third of the U.S. population is vitamin D deficient. Some possible reasons include limited sunlight exposure and a diet low in fish, eggs, and dairy products. Additionally, melanin – the pigment that gives skin its color – makes it more difficult for the sun’s UVB rays to penetrate the skin. Therefore, people who have dark skin must spend more time in the sun to ensure sufficient vitamin D production.

Are you vitamin D deficient?

The signs of a vitamin D deficiency can be very subtle. This is problematic because insufficient vitamin D can lead to a number of health issues – even when symptoms are not present. Some of these issues, such as cardiovascular disease, are potentially serious.

Here are some symptoms that may signal a vitamin D deficiency:

• Extreme fatigue and aching bones – If you feel bone-weary, your body may be taking the calcium it needs from your bones because it is not be absorbing enough dietary calcium due to a vitamin D deficiency.
• Frequent illnesses and infections – A vitamin D deficiency can weaken your immune system, rendering it less effective at fighting off bacteria and viruses.
• Compromised healing – Vitamin D stimulates the production of compounds that are crucial to the formation of new skin during the wound-healing process.
• Gastrointestinal distress – Because vitamin D is a fat-soluble vitamin, a digestive issue that interferes with fat absorption, such as irritable bowel syndrome, can also inhibit the absorption of vitamin D.
• Unexplained sadness – In addition to the production of vitamin D, sunlight exposure stimulates the release of serotonin, a brain chemical that contributes to feelings of well-being and happiness. Therefore, depression associated with a low serotonin level may be accompanied by a low vitamin D level.
