Vitamin D is popularly known as the "sunshine vitamin" because your body makes it when the sun's rays land on your skin. Vitamin D is essential for strong bones because it helps the body use calcium. However, many people don't get enough of this vitamin: a whopping 40% of adults in the United States are vitamin D deficient!

Symptoms of vitamin D deficiency include fatigue, depression, muscle weakness, and more. The good news is that vitamin D deficience, once detected, is usually easy to fix with supplementation and/or sunlight exposure.
