What 4Sight is Best For

4Sight is recommended for people who want to support eye function and also for those seeking macular support as they age.

4Sight may be used for the following:

Antioxidant Support for Eyes
Supports Normal Macular Function
Supports Normal Ocular Circulation

How 4Sight Works

4Sight is part of Ortho Molecular Products Eye Health product line.

In the United States, eye health is a major concern for those over 60 years of age. The eye is the most susceptible organ to oxidative damage caused by light, toxins (smoke), atmospheric oxygen and abrasion. As ultraviolet and blue light pass through the retina to the photoreceptors (rods and cones) and the pigmented epithelial (PE) cells, reactive oxygen species (free radicals) are generated. The conversion of this light energy into a nerve impulse by the photoreceptors generates free radicals; therefore if there are insufficient antioxidants available to neutralize them, the eye undergoes excessive oxidative damage.

4Sight was formulated with a specific blend of botanicals, nutrients, antioxidants and minerals, shown in research to support normal eye function.

4Sight Serving Size

2 capsules per day or as recommended by your health care professional.

4Sight Ingredient

Alpha Lipoic Acid

Alpha lipoic acid (ALA) is an 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, E and glutathione.

Ginkgo Biloba

Ginkgo biloba extract is a well-studied botanical which 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 NO, supporting cerebral blood flow. Ginkgo is a botanical antioxidant that has been shown to concentrate in eye tissues. It has been shown to protect retinal tissue from oxidative damage caused by xenobiotics (chloroquine) and proteolytic enzymes.

Carotenoids: Lutein, Zeaxanthin, Lycopene

Lutein and zeaxanthin are carotenoid pigments whose role in eye health is well-established from epidemiological, clinical and interventional studies. Epidemiologic research shows a connection between high levels of lutein and zeaxanthin in eye tissues and enhanced eye function and visual acuity. Lutein and zeaxanthin supplementation has been shown to protect the lens protein, lipid, and DNA from oxidative damage and improves intracellular redox status upon oxidative stress.

Bilberry

Bilberry extract contains a high amount of the antioxidants known as anthocyanadins, similar to those found in grape seeds. Bilberry has a long history of use in eye health. Its activities include inhibition of aldose reductase, and improving capillary permeability. Bilberry has been shown to protect against an oxidative stress-induced immune response in the mouse uvea and to support night vision. The extract has also been found to support renewal and homeostasis of corneal cells.

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. Researchers have suggested possible functions for taurine in the retina include protection of the photoreceptor, regulation of Ca2+ transport, and regulation of signal transduction.
