Vitamin D and Sarcopenia/Falls

Maintenance of adequate vitamin D status is a stratagem to consider for sarcopenia prevention and treatment. Vitamin D deficiency is common and involves all ages of most racial/ethnic groups and both sexes. Evidence suggests that vitamin D is important for muscle strength and function, and prospective studies are underway to further define these effects. This article summarizes the potential effects of vitamin D on skeletal muscle structure and function and provides guidance for vitamin D supplementation in prevention and treatment of sarcopenia and falls.
