Taking antioxidants and zinc may slow the progression of age-related macular degeneration, a very specific eye condition that affects the macula of the eye and leads to central vision loss. Research studies confirm that people with macular degeneration may benefit from the following combination:
500 milligrams of vitamin C
400 international units (I.U.) of vitamin E
80 milligrams of zinc as zinc oxide
Two milligrams of copper (added to prevent zinc-related copper deficiency)
Omega-3s plus DHA
The Age-Related Eye Disease Study (AREDS) revealed that antioxidants and zinc are responsible for macular health. Although beta-carotene is essential for night vision, studies show that it is really lutein and zeaxanthin (powerful eye antioxidants) that decrease the risk of macular degeneration.
The most common form of macular degeneration is the dry type, accounting for 90% of all cases; the eye’s cells break down and yellow deposits (called drusen) form. As the condition gets worse, a blur in the center line of vision may occur that doctors refer to as geographic atrophy.
Study participants who reported the highest omega-3 intake were at least twice as likely to maintain their vision. They were less likely to go on to develop central geographic atrophy, the cause of central vision loss. With macular degeneration, the peripheral (side) vision still works but there is a loss of the vision directly in front of the person.
The omega-3 fatty acid EPA is a known precursor to DHA, the major omega-3 fatty acid of the eye. This means that EPA has to be converted into DHA, “the major dietary and structural long-chain omega-3 fatty acid” of the eye’s retina.
Taking DHA supplements is good for the macula of the eye, an area of the retina that consists of “millions of light-sensing cells that provide sharp, detailed central vision.” DHA is well known for its ability to halt or alter the processes that lead to age-related macular degeneration.
The high doses of vitamins used in the ARED Study require taking vitamin supplements, as this level of intake is not provided in the diet. Since the typical American diet also lacks long-chain omega-3 in the form of EPA and DHA, the same is true of omega-3. You need to supplement.
Res-Q Recommended Supplements for Eye Support:
Res-Q Calamarine is a Res-Q omega-3 supplement that provides a direct source of DHA to boost brain and eye health. For optimal eye health, take two capsules per day. There are 1,000 milligrams of DHA in two capsules; it would take anywhere from four to 12 fish-oil capsules to provide that amount of DHA. Res-Q Calamarine is therefore not only a superior omega-3 supplement, but also an exceptional savings.
Nature’s Shield Advanced Eye Support contains lutein and zeaxanthin for optimal macular health. This dietary supplement also contains the proper amounts of vitamins C, E and B plus the mineral zinc, critical eye support ingredients that were used in the ARED Study. Nature’s Shield Advanced Eye Support is intended to help maintain healthy vision.
