Glutathione

Meaning

Glutathione is a potent, endogenously produced tripeptide composed of three amino acids: cysteine, glutamic acid, and glycine, and it is recognized as the body’s master antioxidant. Present in virtually all human cells, it plays a pivotal role in protecting cellular components from damage by reactive oxygen species, heavy metals, and xenobiotics. Maintaining optimal intracellular glutathione levels is critical for cellular longevity, detoxification capacity, and the overall resilience of the endocrine system against oxidative stress, which is a key driver of age-related hormonal decline. Clinical interventions often focus on precursor supplementation to support its synthesis.
