Glutathione is one of the universal nutritional factors that apart from performing several body functions is necessary for the maintenance of eye health. It is one of the natural antioxidants produced within the living cells mainly in the liver. Small amounts are typically released from the liver into the bloodstream. Along with other nutrients such as lutein, vitamin E and C, glutathione is one of the most crucial eye health maintaining nutrients. It is for this reason that glutathione is found in most of the eye components such as the lens, optic nerve, and the aqueous fluid.
Glutathione is found in high concentrations in the eye and is essential in the maintenance of its transparency for better vision. Due to its presence in the eye, glutathione functions to detoxify the aqueous fluid in the inner eye. It helps maintain adequate fluid outflow enabling the maintenance of normal eye pressure.
Free radical damage to the eye is deemed to occur due to the light that enters the eye on a daily basis. As a potential antioxidant, glutathione is responsible for the attacking of free radicals in the eye. This minimizes the risk of retinal cell damage, preventing the loss of vision. However, with advancement in age, there is a decrease in the levels of glutathione in the lens which causes clouding of the lens. This may precipitate cataract formation.
Above all, glutathione boosts and facilitates the recycling of other eye health maintaining nutrients such as vitamin E and C. Vitamin C, in particular, is necessary for the regeneration of glutathione level necessary for maintaining eye health potentiating the action of glutathione. In combination with the other antioxidants, glutathione protects against eye damage preventing the onset of macular degeneration or loss of visual acuity.
