Discussion: Glutathione is an essential antioxidant at the cellular level, especially in chronic liver patients. (Often ignored.)

Glutathione is enormously important in the proper functioning of the immune system. Prolonged glutathione deficiency can cause severe illnesses, including cancer. Glutathione cannot be consumed in its active form; the liver must synthesize its active form. (There are glutathione injections on the market, but their effectiveness is unclear.) Eating sulfur-rich foods improves the level of glutathione in the body: avocado, cabbage, Himalayan salt (black), cauliflower, kale, broccoli, onion, and garlic.
