A research team at Nagoya University in Japan has revealed that narrow-range UV irradiation using LED safely increases serum vitamin D levels in aging mice and thereby prevents the loss of their bone and muscle mass. The findings were recently published in the journal Scientific Reports, titled "Low energy irradiation of narrow-range UV-LED prevents osteosarcopenia associated with vitamin D deficiency in senescence-accelerated mouse prone 6.” Decreased bone density (osteoporosis) and the loss of muscle mass and strength (sarcopenia) are age-related disorder...
