Muscle weakness is a common symptom of low blood levels of vitamin D, and could appear as one of the first signs. This may be the case because vitamin D can be found in muscle cells after metabolization. This in turn yields energy for muscle contraction and other functions, used for things like preventing falls and performing a variety of bone-building exercises. So insufficient levels of the vitamin could possibly cause weakness in the muscles. In addition, this deficiency could increase the risk of falls and fractures. Muscle weakness can also be a sign of osteomalacia, a bone disorder caused by inadequate amounts of calcium and vitamin D. Supplemental vitamin D can be used in instances where weakness in the muscles is caused by a lack of vitamin D.Next
