OcuTone, provided by Douglas Laboratories, is a dietary supplement providing a well-balanced spectrum of key nutrients that are important in maintaining normal eye function. OcuTone delivers generous amounts of lutein, beta-carotene, flavonoids, glutathione, sulfurcontaining amino acids, trace elements and a comprehensive array of antioxidant vitamins.
More than any other tissue in the body, the ocular lens and retina are continually exposed to oxygen and intense light radiation. Both light and oxygen can create free radicals that play havoc with lipids in the membranes of visual cells. Experts believe that the uncontrolled generation of free radicals in the eyes can ultimately lead to macular degeneration and cataracts. Therefore, ocular tissues rely on a strong antioxidant defense system to protect them from free radical damage.
OcuTone was formulated to provide a comprehensive combination of antioxidant nutrients that research has found to be important for proper eye nutrition. OcuTone includes nutritionally meaningful amounts of lutein, betacarotene, antioxidant vitamins, the trace elements zinc and selenium, the cellular antioxidants glutathione and N-Acetyl-L-Cysteine, the amino acid taurine, and potent flavonoids from bilberries and grape seeds. Lutein. Lutein is a carotenoid similar to beta-carotene. Recent research has shown that lutein is the major eye pigment of the outer retina. Lutein is especially concentrated in the rods, which are the visual cells of the retina that are responsible for black and white vision in the dark. The rods contain complex membranes rich in polyunsaturated fatty acids that are especially susceptible to lipid peroxidation and free radical damage. Lutein is a potent antioxidant, and researchers believe that the rods require it to protect themselves from light-induced freeradical damage.
Lutein occurs naturally in the diet, especially in dark green leafy vegetables, broccoli and kale. Most people derive about 1 to 2 mg of lutein daily from their diets. Epidemiological studies have shown that daily lutein intakes of 5 to 15 mg may be more appropriate for maintaining normal eye function during aging. As a result, OcuTone was formulated to provide 15 mg of natural lutein complex daily in three capsules.
Beta-Carotene. Beta-Carotene serves at least two purposes for the eyes. It is a valuable precursor for vitamin A which functions in the rod cells as a light receptor. Beta-Carotene is also an important antioxidant in the lens and retina. OcuTone delivers 12 mg of betacarotene daily to ensure a reliable supply of this important eye nutrient.
Vitamins C and E. The healthy ocular lens is rich in the antioxidant vitamins C and E, which scavenge oxygen- and light-induced free radicals. In the lens, excessive free radicals can lead to protein oxidation and polymerization, resulting in opaque, cloudy precipitates. High levels of vitamins C and E, and other natural antioxidant defense systems appear to be necessary for complete protection of the delicate, highly transparent lens proteins. OcuTone provides 500 mg of vitamin C and 400 I.U. of natural vitamin E as d-alpha-tocopherol succinate.
Zinc. Zinc is essential for normal visual signal transduction in the retina. Zinc is part of many of the enzymes involved in vitamin A-dependent light reactions in the rod cells. Moreover, zinc is an essential cofactor of superoxide dismutase, an antioxidant enzyme that removes potentially dangerous superoxide radicals in the visual cells, the lens, and other tissues. OcuTone provides 6 mg of zinc in the highly bioavailable monomethionine form.
Selenium. Selenium is the essential cofactor of the antioxidant enzyme glutathione peroxidase, which is abundant in healthy eyes. Glutathione peroxidase levels, however, decline with advancing age, and experts believe that adequate selen
