Glutathione

Glutathione, often shortened to GSH, is a small molecule naturally made by cells. It is built from three amino acids and plays a major role in protecting cells from oxidative stress. It also helps with detox-related reactions and keeps important proteins working in the right chemical state. Researchers study glutathione in areas such as cell stress, immune function, liver chemistry, mitochondria, aging, and how the body handles outside chemicals. The balance between reduced and oxidized glutathione is also widely used in research to understand how much oxidative stress a cell is under. This gives glutathione a central role in many types of cell research.
