Vitamin D Deficiency Leads To Muscle Problems At The Cellular Level

March 18, 2013: 12:00 AM EST
A British study has found that low levels of the "sunshine vitamin" -- vitamin D -- affect muscle efficiency at the cellular level, explaining why people with low levels often experience fatigue. Vitamin D deficiency is a major public health problem because it not only impacts bone health, it also creates problems in the cell “power stations” known as mitochondria. The problems center on the use and recovery of the muscle-related compound phosphocreatine, a measure of mitochondrial efficiency. In the study, phosphocreatine recovery significantly improved after the patients took a vitamin D supplement for 10-12 weeks. All patients reported an improvement in symptoms of fatigue following supplementation.
