We know that Vitamin D is necessary for good bone health. But there are many other functions for this vitamin. For instance, in recent years we have found that vitamin D can have a strong impact on the body's musculoskeletal system. 

Vitamin D affects your bones, muscles, joints and tissues.

We have known for a long time that vitamin D is important for bone health. One of the jobs of vitamin D is to help your gut absorb the calcium and phosphorus from your diet. These minerals in turn help build and maintain the strength of your bones. Low levels of vitamin D have been linked to stress fractures and other problems with the bones.

But vitamin D has many other functions as well. I describe it to my patients as a delicate symphony of everything that goes on in your body. If one of the instruments — in this case, your vitamin D — is off, it can throw off the whole symphony.

In recent years, we have learned more about how vitamin D affects the entire musculoskeletal system. We recently conducted research that looked at vitamin D levels in young women between the ages of 16 and 40 who were treated in the Women's Sports Medicine Center for a variety of problems with their lower extremities. These included injuries to the ligaments, tendons, cartilage and muscles, as well as the bones.We found that nearly 66% of them had low levels of vitamin D in the blood; about three-fifths were insufficient and the rest were actually deficient. Low blood levels were found in patients with acute injuries as well as overuse injuries. Because these rates of low vitamin D are higher than what's seen in the general population, they suggest a link between low vitamin D and musculoskeletal injuries. More research is needed to confirm this connection.
