Full Study Name

Is Treatment of Vitamin D Deficiency Associated with Resolution of Statin-Induced Muscular Symptoms (IRB no. 23187)


The purpose of this study is to examine whether treatment with vitamin D can alleviate statin-induced muscle pain in subjects with vitamin D deficiency. Statins are a class of drugs that are highly effective at lowering cholesterol levels. However, use of statins is often limited by symptoms of muscle pain.

Vitamin D2 is approved by the U.S. Food and Drug Administration (FDA) to treat various conditions. However, vitamin D has not been systematically studied to test its potential benefits in patients who suffer from statin-induced muscle pain.
