Vitamin D lowers AMD: study

Higher levels of circulating vitamin D appear to reduce the risk for early onset of age-related macular degeneration in women ages 50 to 74, an ancillary study reported in Archives of Ophthalmology. Among postmenopausal women younger than 75, those who had the highest concentrations of 25 (OH)D (at least 75 nmol/L) were significantly less likely to develop the eye condition than those with the lowest (38 nmol/L or lower). There was not association between time spent in direct sunlight and the likelihood of developing macular degeneration.
