In a randomized, controlled, double-blind study, researchers found that supplementing with lutein and vitamin A may slow development of retinitis pigmentosa.
They found that use of a daily supplement of 12 milligrams of lutein formulated with with 15,000 IU of vitamin A was linked to protection of mid-peripheral vision.
This new data suggests that 40 year olds with retinis pigmentosa who take vitamin A plus lutein would have their mid-peripheral field for an extra 21 years when compared to people not taking the combination. Previous studies have found vitamin A slows the decline in retinal function and vision loss, and this study indicates that combining vitamin A with lutein is better.
Since there has been some concern with regard to smokers and lutein supplementation, this study looked only at non-smokers.
