Glutathione, the body's master antioxidant and detoxifier, is one of the 14 "Superfoods" listed in SuperFoods Rx : Fourteen Foods That Will Change Your Life, co-authored by Dr Steven Pratt.
Glutathione levels cannot be increased to a clinically beneficial extent by orally ingesting a single dose of Glutathione.
This is because Glutathione is manufactured inside the cell, from its precursor amino acids, glycine, glutamate and cystine.
Hence food sources or supplements that increase Glutathione must either provide the precursors of glutathione, or enhance its production by some other means.
The manufacture of Glutathione in cells is limited by the levels of its sulphur-containing precursor amino acid, cysteine.
Cysteine - as a free amino acid - is potentially toxic and is spontaneously catabolized or destroyed in the gastrointestinal tract and blood plasma.
However, when it is present as a cysteine-cysteine dipeptide, called cystine, it is more stable than cysteine.
Consuming foods rich in sulphur-containing amino acids can help boost Glutathione levels. by: Priya F Shah
