Glutathione is an antioxidant found naturally in your body. Also known as GSH, it is produced by the liver and nerve cells in the central nervous system and is made from three amino acids: glycine, L-cysteine, and L-glutamate. Glutathione can help metabolize toxins, break down free radicals, support immune function, and more.

Glutathione supplements are often recommended for several health conditions, including Alzheimer's and heart disease. It is also used in dermatology to lighten skin and fight the visible signs of aging. However, there is very little scientific evidence to support these uses.

This article discusses the antioxidant glutathione along with its uses and purported benefits. It also provides examples of how to get more glutathione in your diet.

Dietary supplements are not regulated like drugs in the United States, meaning the Food and Drug Administration (FDA) does not approve them for safety and effectiveness before products are marketed. When possible, choose a supplement that has been tested by a trusted third party, such as USP, ConsumerLabs, or NSF.

However, even if supplements are third-party tested, that doesn't mean they are necessarily safe for all or effective in general. Therefore, it is important to talk to your healthcare provider about any supplements you plan to take and to check in about any potential interactions with other supplements or medications.
