4Sight provides excellent support for those who want to maintain eye health and also for those seeking macular support as they age.
Alpha Lipoic Acid Alpha lipoic acid (ALA) is a potent, versatile antioxidant that is both water- and fat-soluble. ALA has been shown to inhibit aldose reductase, which prevents sorbitol-induced leakage of important antioxidants from eye tissues and recharges ALA, vitamin C, vitamin E and glutathione. Ginkgo biloba Ginkgo biloba extract is a well-studied botanical that increases cerebral blood flow and protects neurons from a variety of conditions and oxidant-induced damage. It scavenges NOS (nitric oxide species) and ROS (reactive oxygen species), supports mitochondrial function, inhibits NMDA receptor activation, antagonizes PAF (platelet activating factor), and stimulates the release of NOS to support cerebral blood flow. It has been shown to provide key antioxidant support for eyes. Carotenoids: Lutein, Zeaxanthin, Lycopene Lutein and zeaxanthin are carotenoid pigments whose role in eye health is well-established from epidemiological, clinical and interventional studies.
