Glutathione

Glutathione is a tripeptide composed of the three amino acids &emdash; glycine, glutamic acid (glutamate), and cysteine. Dietary glutathione can be found in fruit and vegetables, especially asparagus, avocado, and walnuts, fish, and meat.

Glutathione has been called the "master antioxidant," in addition to its own potent antioxidant powers glutathione helps to recycle other antioxidants such as vitamins C and E. Thus, glutathione can help to protect against cancer and other diseases caused by oxidative damage. Glutathione also plays an important role in the regulation of immune cells, and is a potent detoxifying agent. Low levels of glutathione have been associated with hepatic dysfunction, immune dysfunction, cardiac disease, and premature aging. It is also important in DNA synthesis and repair, protein and prostaglandin synthesis, and amino acid transport. Several studies have shown that glutathione has antiviral properties. Research has shown that glutathione inhibits activation of the HIV virus, therefore it may be beneficial to people with HIV and AIDS.

There are no known symptoms of glutathione deficiency, however some medical conditions are associated with glutathione deficiency, for example diabetes, low sperm count, and liver disease. Heavy smokers may have low levels as certain chemicals in tobacco smoke increase the rate at which the body utilizes glutathione.

Refer to dosage instructions on packaging. People with a proven glutathione deficiency should be treated by a doctor, and may require intravenous or intramuscular injections. Some research suggests that taking oral glutathione may not be the best way of raising blood glutathione levels. One study showed that healthy people could raise their blood glutathione levels by nearly 50% by taking 500mg of vitamin C each day for 2-weeks. Other nutritional compounds that may help to boost glutathione levels include: alpha lipoic acid, glutamine, methionine, S-adenosyl methionine (SAMe), and whey protein.

MAXIMUM SAFE LEVEL: Not established

People with kidney or liver disease should consult their doctor before taking supplementary glutathione.

VIDEO: Brain Age Workshop
Dr. Eric Braverman, Director of The Place for Achieving Total Health (PATH Medical), Chairs the Brain Age Workshop taking place Dec. 9, 2009. Held in conjunction with the Winter Session of the 17th Annual World Congress on Anti-Aging Medicine & Regenerative Biomedical Technologies. The Brain Age Workshop features presentations on Brain Mind Assessment via Neuropsychological Analysis, Movement Deficiency Syndrome, Hormones and the Brain, Nootropic Drug Mechanisms, and Traumatic Brain Injury. View this video to learn about Dr. Braverman’s brain-based model of aging and age modulation.
