Glutathione
Also indexed as: GSH
Glutathione is a small protein composed of three amino acids: cysteine, glutamic acid, and glycine.
Glutathione is involved in detoxification—it binds to toxins, such as heavy metals, solvents, and pesticides, and transforms them into a form that can be excreted in urine or bile. Glutathione is also an important antioxidant. In preliminary research, dietary glutathione intake from fruit and raw vegetables has been associated with protection against some forms of cancer.1 2 Glutathione has also inhibited cancer in test tube3 and animal studies.4 In preliminary research, higher glutathione levels have also been associated with good health in older adults.5
Glutathione supplements appear to be efficiently absorbed in rats.6 7 However, the same may not be true for glutathione supplements in humans. For example, when seven healthy people were given a single application of up to 3,000 mg of glutathione, there was no increase in blood glutathione levels.8 The authors of the study concluded "it is not feasible to increase circulating glutathione to a clinically beneficial extent by the oral administrating of a single application of 3,000 mg of glutathione." Absorption of glutathione may be better in rats because unlike the gastrointestinal tract of rats, the human gastrointestinal tract contains significant amounts of an enzyme (gamma-glutamyltranspeptidase) that breaks down glutathione. Preliminary evidence has suggested that absorption of glutathione can occur in the mouth when glutathione tablets are placed between the teeth and the inner cheek.9
Some researchers believe that supplements other than oral glutathione may be more effective in raising blood levels of glutathione. For example, in one trial, blood glutathione levels rose nearly 50% in healthy people taking 500 mg of vitamin C per day for only two weeks. Vitamin C raises glutathione by helping the body manufacture it. In addition to vitamin C, other nutritional compounds that may, according to preliminary research, help increase glutathione levels include alpha lipoic acid, glutamine, methionine, S-adenosyl methionine (SAMe), and whey protein. Vitamin B6, riboflavin, and selenium are required in the manufacture of glutathione. The extent to which any of these nutrients effectively increases glutathione levels in humans remains unclear.
