Glutathione

Glutathione, often referred to as the 'master antioxidant', is a tripeptide molecule found in virtually every cell of the body. It is endogenously synthesized from the amino acids L-cysteine, L-glutamic acid, and glycine, and its primary function involves protecting the body from damage by reactive oxygen species, heavy metals, and various toxins. This makes it fundamental for maintaining cellular integrity and overall health. Beyond its direct antioxidant activity, glutathione is vital for numerous cellular processes including DNA synthesis and repair, protein synthesis, enzyme activation, and immune system function. It is particularly concentrated in the liver, where it assists in the detoxification of both endogenous and exogenous compounds, making it a cornerstone of the body's natural defense system against environmental pollutants and metabolic waste products. Maintaining adequate levels of glutathione is crucial for health, especially as levels can decline with age, poor nutrition, chronic stress, and exposure to toxins. Supplementation or supporting its natural production through precursors and cofactors is often pursued to bolster antioxidant defenses, support liver health, and enhance immune responses, contributing to cellular vitality and disease prevention.
