Study: Glutathione - Antioxidant (2000)

Glutathione, which is particularly concentrated in the lens, has been shown to have a hydroxyl radical-scavenging function in lens epithelial cells. Giblin FJ. Glutathione: a vital lens antioxidant. J Ocul Pharmacol Ther 2000 Apr; 16(2):121-35.

An age-dependent drop in glutathione blood status and a significantly lower level of glutathione has been found in older individuals compared to younger ones. Moreover, an increase of oxidized glutathione by-product over time suggests more oxidation and the incumbent higher risk of age-related eye diseases. Brubaker RF, et al.
