Glutathione’s power lies in its role as a potent antioxidant and its involvement in several key cellular processes. As a tripeptide (made of three amino acids), it neutralizes free radicals by donating its electrons, effectively preventing these unstable molecules from damaging cells, DNA, and other vital components. This action is crucial in reducing oxidative stress, a major contributor to aging and various diseases. Beyond direct antioxidant activity, glutathione also plays a critical role in detoxifying the liver. It participates in Phase II detoxification pathways, where it conjugates with toxins, making them water-soluble and easier to excrete. Furthermore, glutathione is essential for immune function, supporting the proliferation and activity of lymphocytes (a type of white blood cell) and maintaining a balanced immune response. It also contributes to the regeneration of other antioxidants, such as vitamins C and E, further amplifying its protective effects. Finally, glutathione is involved in various metabolic processes and helps maintain cellular redox balance, a critical factor for cell survival and function.
