Reduced glutathione predominantly exists in its reduced state. This is because the enzyme glutathione reductase, which converts it from the oxidized form, has constitutive activity and can be activated during oxidative stress. In reality, the ratio of reduced glutathione to oxidized glutathione in cells is commonly used as a scientific measure of cytotoxicity.

Introduction of Reduced Glutathione
It is an antioxidant that safeguards vital cell components from damage caused by reactive oxygen species like free radicals and peroxides.
Benefits of Reduced Glutathione
- Reduced glutathione is the primary endogenous antioxidant produced by cells. It is directly involved in the neutralization of free radicals and reactive oxygen compounds, and helps maintain the reduced (active) form of exogenous antioxidants such as vitamins C and E.
- Through direct combination, it can detoxify numerous organic and inorganic foreign substances (xenobiotics) and carcinogens, including heavy metals like mercury, lead, and arsenic.
- Reduced glutathione is crucial for the immune system to function at its best. For example, (1) It regulates the presentation of antigens to lymphocytes, thereby influencing the production of cytokines and the type of immune response (cell - mediated or humoral); (2) It enhances the proliferation of lymphocytes to boost the intensity of the immune response; (3) It increases the killing activity of cytotoxic T cells and NK cells; (4) It regulates apoptosis to keep the immune response in check.
- It plays a fundamental role in many metabolic and biochemical reactions, such as DNA synthesis and repair, protein synthesis, prostaglandin synthesis, amino acid transport, and enzyme activation. Therefore, every system in the body is affected by the status of the glutathione system, especially the immune, nervous, gastrointestinal, and respiratory systems.
