Insufficient intake of vitamin D may lead to decreased physical strength, increased muscle weakness and increased risk of disability in older women and men, according to a new study published in the Journal of Gerontology: Medical Sciences.
Because vitamin D deficiency is widespread, the researchers have suggested that increasing vitamin D intake may help older adults decrease their risk of disability and maintain better muscle strength and physical performance.
Researchers measured the serum levels of 25-hydroxy-vitamin D for 976 adults over the age of 64. They also took measures of grip strength -- which is a good predictor of the risk of future disability -- and physical performance.
