LED-based UV irradiation safely prevents the loss of bone and muscle mass in mice

A research team at Nagoya University in Japan has revealed that narrow-range ultraviolet (UV) irradiation using light emitting diodes (LEDs) safely increases serum vitamin D levels in aging mice and thereby prevents the loss of their bone and muscle

Decreased bone density (osteoporosis) and the loss of muscle mass and strength (sarcopenia) are age-related disorders. While there are some remedies for osteoporosis, there is no effective treatment for sarcopenia.
