Glutathione is a type of antioxidant made naturally by the human body. However, it is also available in the form of a supplement and is claimed to help treat or prevent several conditions, such as glaucoma, heart disease, and asthma. Although studies have shown that glutathione may not be well absorbed when taken by mouth, it may be effective for some uses when administered intravenously.

How Does Glutathione Work?

Glutathione works as an antioxidant, helping to prevent free radical damage to cells. It is also important for making DNA, proteins, and other substances in the body. It helps to metabolize toxins and carcinogens (cancer-causing compounds) and is important for immune function. The body can make its own glutathione in the liver, and some foods (fruits, vegetables, and meats) contain it. However, studies seem to suggest that it may not be well absorbed when taken by mouth (either as food or as a dietary supplement).
