Doctors said that one of the factors leading to AMD is inflammation, and that prior research suggests vitamin D may help prevent diseases caused by inflammation.
In one study, researchers measured blood serum levels of 25-hydroxyvitamin D—which reflects both vitamin D levels from the sun and from food—in 1,313 postmenopausal women.
Although higher vitamin D levels did not reduce chances of AMD for women aged 75 and older, for women under age 75, those who consumed the most vitamin D were 59 percent less likely to develop early AMD as were women who consumed the least.
