Glutathione (GSH) is a compound made of three amino acids that act as a powerful antioxidant in the body. Researchers believe that the level of Glutathione in cells may indicate how long an organism will live. Glutathione helps the body in detoxification by eliminating harmful molecules and plays a crucial role in various cellular functions.

It is essential for reducing DNA and RNA nucleotides and regulating protein and gene expression. Glutathione can exist in an oxidized or reduced state within cells. The balance between these states is crucial for cell survival. A deficiency in glutathione can lead to oxidative damage and is associated with various health issues like cancer, neurodegenerative disorders, and aging.

Even though the body can produce its own glutathione from amino acids, it is not classified as an essential nutrient. Glutathione is integral for maintaining a healthy immune system and overall health by neutralizing free radicals that can harm cells through oxidation. It is widely present in all cells and is considered one of the most important antioxidants in the body.
