Glutathione is an antioxidant produced in cells. It’s comprised largely of three amino acids: glutamine, glycine, and cysteine.
Glutathione levels in the body may be reduced by a number of factors, including poor nutrition, environmental toxins, and stress. Its levels also decline with age.
In addition to being produced naturally by the body, glutathione can be given intravenously, topically, or as an inhalant. It’s also available as an oral supplement in capsule and liquid form. However,
1. Reduces oxidative stress
Oxidative stress occurs when there’s an imbalance between the production of free radicals and the body’s ability to fight them off. Too-high levels of oxidative stress may be a precursor to multiple diseases. These include diabetes, cancer, and rheumatoid arthritis. Glutathione helps stave off the impact of oxidative stress, which may, in turn, reduce disease.
An article cited in Journal of Cancer Science and Therapy indicated that glutathione deficiency leads to increased levels of oxidative stress, which might lead to cancer. It also stated that elevated glutathione levels raised antioxidant levels and resistance to oxidative stress in cancer cells.
