Glutathione is a critical antioxidant. It protects the liver and prevents damage to cells caused by reactive oxygen species such as free radicals, peroxides, and heavy metals.
Glutathione is comprised of amino acids glycine, cystine and glutamine. Cystein contains a sulfur molecule, which gives glutathione it’s distinct aroma of a rotten egg.
Low glutathione levels have been associated with a decrease in immune function and found to promote immunity against infections like tuberculosis.
There is no point in taking oral capsules of glutathione because it would be denatured by the digestive tract. If you prefer capsules, you can start with nutrients that boost your production of glutathione, such as NAC, selenium and Vitamin C.
Glutathione can be taken in a liposomal form for direct oral absorption, or as a suppository, intramuscular injection or intravenous push for maximum absorption.
Blood levels of glutathione can be tested to measure benefit.
