Glutathione is a powerful antioxidant that is naturally produced by the body. It plays a crucial role in protecting cells from damage caused by free radicals and other harmful substances. It is found in high concentrations in the liver, where it helps to detoxify harmful substances. Glutathione is also important for maintaining a healthy immune system, as it helps to regulate the activity of white blood cells. Glutathione may also have anti-aging properties and could be beneficial in treating certain health conditions related to ageing.
