Glutathione is widely recognised in biomedical science as the master antioxidant due to its central role in cellular protection, detoxification and redox balance.
Inside the eye, the aqueous humor is a clear fluid responsible for maintaining intraocular pressure, delivering nutrients and removing metabolic waste. Proper outflow of this fluid is essential. When outflow is impaired, pressure builds up, placing stress on the optic nerve, which is a defining feature of glaucoma.
Scientific research has shown that Glutathione plays an important role in detoxifying the aqueous fluid of the inner eye. By neutralising oxidative stress and reactive oxygen species, Glutathione helps protect the delicate structures involved in fluid regulation, including the trabecular meshwork, which controls aqueous outflow.
Reduced glutathione levels have been associated with increased oxidative damage in ocular tissues. This oxidative burden may contribute to impaired fluid drainage, elevated intraocular pressure and progressive optic nerve damage. Supporting Glutathione status is therefore seen in scientific literature as a key factor in maintaining a healthier ocular environment.
Glutathione does not treat glaucoma, but it supports the biological systems responsible for antioxidant defence, detoxification and fluid balance within the eye. This aligns with broader ophthalmology research where oxidative stress is increasingly recognised as a contributing factor in age-related eye disorders.
When antioxidant defence is strong, the eye is better equipped to maintain balance function and long-term resilience.
