Macular Support Formula™ is a combination of potent antioxidants and botanicals designed to protect and support the macula, the central area of the retina responsible for sharp vision. Since the macula is extremely susceptible to free radical damage, current research stresses the importance of antioxidant supplementation in maintaining macular health.

N-acetyl-l-cysteine is a powerful antioxidant and glutathione precursor. In animal studies, it has been shown to protect against oxidative damage to the lens and to support healthy glutathione levels. Glutathione is one of the natural antioxidants found in retinal tissues. In times of oxidative stress, or aging, when more free radicals are being produced, supplementation with NAC and reduced glutathione may provide enhanced support for macular health. Bilberry, containing anthocyanidins, has been shown to moderate visual fatigue and to improve light to dark adjustments. Grape seed extract is another powerful antioxidant and helps support antioxidant balance in the retina. This formula is also enhanced with lutein, one of only two carotenoids found in macular pigment. Lutein promotes the integrity and density of the macular pigment. The antioxidant activity of lutein also provides optimal protection of the macula from light. In addition, lutein helps to maintain the health of the optical lens. Mixed carotenoids provide zeaxanthin, the other carotenoid found in macular pigments, as well as other carotenoids for antioxidant support. Vitamin C, possibly due to its status as an antioxidant, has been shown to support ocular health in laboratory animals.
