Vitamin D is increasingly recognised to play an important role in normal muscle function. Low vitamin D status is associated with an increased risk of falls and proximal weakness.

Since vitamin D deficiency is very common, and the signs are non-specific, it is important to maintain a high index of suspicion of vitamin D deficiency in patients with muscle pain and weakness, and it is simple to measure serum 25(OH) vitamin D.

Therapy is cheap, safe and effective, but sometimes a larger dose may be needed, and, as shown in our case report, willingness of people to pay for an over the counter medication can be an issue.

Following a striking case report that demonstrates muscle defects in severe vitamin D deficiency, we discuss clinical studies examining specific effects of vitamin D on physical performance, muscle strength and falls. Finally, we present an overview of molecular mechanisms that explain vitamin D's biological effects on muscle.
