- Supports healthy eye function with potent carotenoid antioxidant blend.*
- Provides structural support for the eyes with DHA, an omega-3 fatty acid essential for proper vision.*
Essential Vitamin & Minerals- Both vitamin A and beta-carotene are required by eyes for normal, healthy function.* Also contains vitamins C and E and essential minerals such as selenium, copper and zinc that play an integral role in maintaining normal ocular function.*
Antioxidant & Structural Support- Provides powerful antioxidants, including lutein, zeaxanthin and glutathione that work to protect eyes from oxidative damage.* The superior form of lutein in this formula has been shown to have 268% greater bioavailability than regular lutein. Zeaxanthin, a carotenoid found in the retina, has also been shown to support eye health.* DHA is an essential omega-3 fatty acid found in the eye membranes and is an important structural component of the eye for healthy vision.*
Blood Flow Support- Contains important nutrients to support healthy blood flow which is essential for eye healthy, including resVida® Resveratrol, clinically shown to enhance blood vessel dilation**, and bilberry, an antioxidant that helps protect ocular cells and supports enhanced blood circulation and healthy eye function.*

- Health Notes
Focus on Eye Health SupplementsFocus on Eye Health SupplementsReplacing the beta-carotene with carotenoids lutein and zeaxanthin provided the same benefits for all while reducing lung cancer risk the original formula increased in former smokersDHA, an omega-3 fatty acid from fish oil, plays an important role in developing prenatal and infant visual systems and has been associated with reduced risk of macular degeneration in observational research. Despite some promising double-blind research also showing benefit of certain nutrient combinations for people already diagnosed with macular degeneration, a new study in the Journal of the American Medical Association found that adding omega-3s to a nutrient combination did not slow down disease progression any more than that same formulation on its own. However, they did find that replacing the beta-carotene in that formulation with other carotenoids provided the same benefits while preventing increased lung cancer risk the original formula caused in former smokers.
Uncovering the keys to eye health
Age-related macular degeneration is the leading cause of blindness in the developed world. It happens when the macula-a yellow spot on the retina of the eye-is damaged, leading to progressive central vision loss.
In 2001, the Age-Related Eye Disease Study (ARMDS) found that taking an antioxidant supplement containing vitamin C, vitamin E, beta-carotene, and zinc could reduce the risk of macular degeneration progression by about 25% in people with the disease. Since then, other studies have suggested that additional nutrients might also help people with macular degeneration.
The first of these are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) found in fish oil. Observational studies have suggested that people who eat more fish containing these omega-3 fatty acids have a lower risk of macular degeneration.
Lutein and zeaxanthin are antioxidants found in green leafy vegetables, corn, egg yolks, and broccoli. These carotenoids are found in high concentrations in the macula and lend the macula its bright yellow appearance. A recent study showed that a combination of omega-3s and lutein and zeaxanthin could increase macular pigment density in people with macular degeneration, a factor associated with decreased risk of the disease.
Fine-tuning the formula
For the new study, called AREDS2, researchers decided to make some changes to the original AREDS supplement to see how different formulations would affect macular degeneration progression. Over 4,000 people aged 50 to 85 years who were at risk for advanced macular degeneration took part in the 5-year study.
- The control group took the standard AREDS formula.
- One group took the AREDS formula with 10 mg of lutein and 2 mg of zeaxanthin.
- One group took the AREDS formula with 650 mg of EPA and 350 mg of DHA.
- Another group took the AREDS formula with all four of these ingredients.
They also made some other changes to the formula, including decreasing the amount of zinc and swapping out the beta-carotene for lutein and zeaxanthin. High doses of zinc can cause stomach upset and beta-carotene may increase lung cancer risk in smokers, limiting its use in these people.
Here are the highlights of the study's findings:
- Adding lutein and zeaxanthin or DHA and EPA to the formula didn't change the supplement's effectiveness.
- Adding all four ingredients to the formula also didn't change the supplement's effectiveness.
- Lowering the zinc dose didn't change the effectiveness of the supplement, but it did decrease the likelihood of stomach upset.
- Substituting lutein and zeaxanthin for the beta-carotene didn't take away from the positive effects of the supplement on eye health.
"Because of potential increased incidence of lung cancer in former smokers, lutein and zeaxanthin could be an appropriate carotenoid substitute in the AREDS formulation," commented lead study author, Dr. Emily Chew of the National Eye Institute at the National Institutes of Health.
See the light
To help prevent macular degeneration, eye health experts recommend getting regular exercise, avoiding smoking, eating fish at least once a week, and consuming plenty of antioxidant-rich foods. Chopping, pureeing, and cooking carotenoid-containing foods in oil help make their beneficial compounds more absorbable.
