The best answer to the question "Will lutein improve vision if one adds it to their daily nutrition?" is "Yes" if you are a sufferer of age-related macular degeneration (AMD).
Non-sufferers will also benefit in the form of vision protection.
Lutein is an eye pigment, found in the macula area of the retina.
It helps protect against high energy light and the results of oxidative processes that go on there.
One must always include the companion pigment zeaxanthin, which is found in the more peripheral area of the retina.
The two are often described as macular pigment.
As we grow older - some think from about 50 - the concentrations of both macular pigments change.
This is related to the onset of age-related macular degeneration (AMD) which results in a gradual loss of central vision.
There is some evidence that low levels of macular pigment increase the risk of developing age-related macular degeneration.
There are also results of studies that show that supplementation with the macular pigments helps protect against AMD.
In the Lutein Antioxidant Supplementation Trial (LAST), the authors concluded that supplementation improved eye function.
This improvement was in the form of visual function, glare recovery, and contrast sensitivity.
So the answer to the question "will lutein improve vision" is yes for sufferers of AMD.
Those who are not yet affected are still also advised to take it as it will protect against or delay the onset of age-related macular degeneration.
One obvious source is the diet and foods like eggs, Brussels sprouts, peas, turnip greens, romaine lettuce, kale, collard greens, broccoli, zucchini and broccoli are good sources.
The intake from food is not always measurable, one does not always feel like having so many veggies and the accompanying fat or oil that is needed to ensure absorption may not be a part of the meal.
A nutritional supplement is a good source which gets round the dietary challenges.
This is highly recommended provided it comes as part of a multi-ingredient nutraceutical rather than a single substance formulation.
Vision support requires a multiplicity of nutrients and includes zeaxanthin, bilberry and vitamins.
The amount of lutein provided must also be sufficient to meet the recommended minimum daily requirement of between 6 and 30mg.
I am aware from personal usage of a product that contains at least 90 ingredients to cover the needs of not only vision, but also the effects of aging in general.
The ingredients include lutein, zeaxanthin, bilberry, multi-vitamins, resveratrol, ginko biloba and many others.
