For the study, researchers recruited 225 healthy men and women between the ages 18 and 60 with retinitis pigmentosa. They randomly divided the participants into two groups. One group received 15,000 IU of vitamin A daily for four years. The other group received the same amount of vitamin A, plus 12 mg of lutein each day for four years. Then, at the end of the study, each of the participants took a vision test.

Vitamin A and lutein adds 10 years of vision

Researchers found that the patients who took vitamin A plus lutein didn‘t lose their peripheral vision nearly as fast as the control group did. In fact, the data suggested that a 40 year old who took vitamin A plus lutein would not lose peripheral vision until the age of 61. That‘s a significant improvement, when you consider that same 40 year old would normally lose most peripheral vision by age 51. And even though this isn‘t a cure for the disease, it‘s a big step in the right direction. Plus, it‘s completely non-toxic.

You‘ll find vitamin A, the powerhouse for your eyes, in lots of bright, colourful vegetables like bell peppers, carrots, and sweet potatoes. Lutein is found in green leafy vegetables and eggs and is also taken to reduce the risk of macular degeneration. So you can easily stock up on this important combo, simply by making yourself a delicious summer salad.
