Why are there multiple VisiVite formulas?
VisiVite Original Formula duplicates the ingredients in the National Eye Institute’s Age Related Eye Disease Study. But Lutein was not available at the time of that study, and is found in VisiVite i-Defense Yellow, Red, Gold and Green Formulas. Beta-carotene was shown in two large studies to increase the risk of lung cancer in smokers. Therefore, VisiVite i-Defense Red and Green Formulas contain no Beta-carotene for people who have habitually smoked within the past 20 years.. Finally, only VisiVite Gold and Green Formulas contain additional Zeaxanthin.
