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.
Why These Natural Ingredients?
Ginkgo Biloba - Ginkgo biloba has historically been used to promote blood flow and is used as an antioxidant. Some studies have shown that eye tissue has a high affinity for ginkgo, making it a logical choice for eye support.
Carotenoids (Lutein, Lycopene, Zeaxanthin) - Lutein and zeaxanthin are found in high concentrations in the macula lutea portion of the eye. These two carotenoids are strong antioxidants that quench free radicals and support healthy lipid membranes. Low levels of lycopene, one of 10 carotenoids found in the serum, should be boosted for optimal eye health.
Bilberry - Bilberry extract contains high amounts of anthocyanidins, important antioxidants shown to support healthy vision.
Quercetin - A flavonoid found in a variety of herbs, vegetables and fruits, quercetin is a potent antioxidant which modulates pro-inflammatory pathways by inhibiting inducible ICAM- 1 expression. It has been shown to enhance epithelial barrier function in the intestines, to stabilize mast cells by releasing cytoprotective factors and to promote balanced proinflammatory mast cell mediators.
Taurine - Taurine concentration is high in the retina and is required for retinal tissue growth. It has been shown to protect rod outer segments from oxidative damage and to protect lens tissue from radiation. Researchers have suggested possible functions for taurine in the retina include protection of the photoreceptor, regulation of Ca2+ transport, and regulation of signal transduction.
