Glutathione, also known as GSH, is a molecule found naturally in your body. Produced by the liver as well as by neurons in the central nervous system, glutathione is made up of three amino acids: L-cysteine, glycine, and L-glutamate. Glutathione is an antioxidant. It is involved in metabolism of toxins and carcinogens, DNA synthesis and repair, protein and prostaglandin synthesis, amino acid transport, immune system function, prevention of oxidative cell damage, and enzyme activation. Glutathione is said to protect against a wide range of health problems, including atherosclerosis, Lyme disease, Alzheimer's disease, chronic fatigue syndrome, colitis, high cholesterol, osteoarthritis, alcoholism, asthma, cataracts, diabetes, glaucoma, heart disease, hepatitis, liver disease, and Parkinson's disease. Glutathione deficiency has also been linked to children with autism. Most recently scientists have discovered that a lack in glutathione and vitamin D is a contributing factor in serious manifestations and death due to COVID19. Glutathione is considered a powerful anti-oxidant and helps protect the body against oxidative stress. COVID19 increases the oxidative damage in the lungs thus leading to hyper-inflammation. Glutathione is found naturally in certain fruits and vegetables as well as freshly prepared meats.
