4Sight provides excellent support for those who want to maintain eye health, and also for those with age-related antioxidant issues. Developed in conjunction with a nationally known Ophthalmologist, 4Sight was in the trenches giving support to those who needed it, long before age-related antioxidant issues made the headlines with such great media exposure. Ingredients used in 4Sight are of the upmost quality, ensuring you the proper support your eyes deserve. Many of the ingredients included in 4Sight, such as lycopene and lutein, have been used in studies for their role in supporting eye health.
Alpha-lipoic acid is most widely known and used as an antioxidant. Lipoic acid is able to recharge other antioxidants such as vitamins E and C, and glutathione and has been shown in studies to improve visual function.
Ginkgo biloba has historically been used to increase blood flow and and is used as an antioxidant. A few studies have shown that eye tissue has a high affinity for ginkgo, making it a logical choice for eye support.
Lutein and zeaxanthin are found in high concentrations in the macula lutea portion of the eye. These two carotenoids are thought to quench free-radicals before they damage the lipid membranes. Low levels of lycopene, one of 10 carotenoids found in the serum, has also been shown to be a risk factor for poor eye health.
Bilberry extract contains high amounts of anthocyanadins, components used in countries such as France and Germany for night vision support.
