Glutathione (GSH) is a tripeptide composed of three amino acids: glutamate, cysteine, and glycine. It is an essential molecule in the human body, present in virtually all cells, and performs multiple functions critical to health.

1. Powerful Antioxidant

Description: Glutathione is one of the most important antioxidants in the human body. It protects cells from oxidative damage by neutralizing free radicals and other reactive oxygen species (ROS).

Scientific Evidence: Several studies have shown that glutathione plays a crucial role in protecting cells from oxidative stress. For example, a review of the scientific literature highlights glutathione's ability to reduce cellular damage and prevent diseases related to oxidative stress, such as cancer, cardiovascular disease, and neurodegenerative diseases.

2. Support the Immune System

Description: Glutathione is essential for the proper functioning of the immune system. It helps maintain the integrity and functionality of T lymphocytes, a type of white blood cell crucial to the adaptive immune response.

Scientific Evidence: Research has shown that adequate levels of glutathione in immune cells are vital for their proliferation and activity. A study published in the European Journal of Clinical Investigation found that glutathione supplementation can improve immune response in individuals with deficiencies, as well as in older people, whose immune function tends to decline with age.

3. Liver Detoxification

Description: Glutathione plays a key role in liver detoxification. It is involved in the conjugation and elimination of toxins and harmful substances, facilitating their excretion from the body.

Scientific Evidence: Glutathione is critical in Phase II of liver detoxification, where it binds to toxic compounds, making them more water-soluble and facilitating their elimination through bile or urine. Studies have documented its effectiveness in protecting the liver against various hepatotoxic agents, including alcohol and certain medications. An article in the "Journal of Hepatology" describes how glutathione supplementation can protect against toxin-induced liver damage and improve liver function in patients with chronic liver disease.
