Glutathione: Health Info. Xanya Sofra Weiss

Nevertheless, people have tried glutathione for the treatment of a whole host of conditions, including cancer, high blood pressure, Parkinson's disease, Alzheimer's disease, cataracts, and male infertility.

The best studies have been conducted in cancer. One study involved women with ovarian cancer who were being treated with chemotherapy. Some of the women were also treated with intravenous glutathione. Those given the glutathione not only had fewer side effects from the chemotherapy but also had better overall survival rates.

Myriam Abalain of Montreal, Canada, is one of the many people who have taken Bounous's Immunocal to combat cancer. In 1996, at age 33, a routine PAP smear revealed she had precancerous cells on her cervix, which is one step away from having cervical cancer. The three specialists she visited all told her that a hysterectomy was her only option, but she hesitated to have such major, life-altering surgery.

Instead, she waited. For more than two years, her condition remained stable. Then a friend suggested she try Immunocal. After eight months of taking the supplement, her physician could no longer detect any precancerous cells. Does this mean Immunocal cured her? It's hard to say based on just one case like hers. It is possible her body went into remission naturally.

Even Bounous acknowledges there's no real proof his product cured her cancer, but he's working on conducting good clinical research, comparing individuals with cancer taking glutathione to those who are not.

What Are the Risks?

Overall, taking glutathione or its precursors in reasonable amounts appears to be quite safe, although it should be avoided in people with milk protein allergies and in those who have received an organ transplant. There is also some concern, however, about the safety of taking glutathione for the one condition for which there is the greatest evidence of its usefulness: cancer.

"People don't get concerned about these health-promoting [supplements] until they're in their 50s and 60s," says Emory's Dean Jones. At that point, they may already have the initial precancerous [cells]. Therefore, the supplements, just like they promote health in normal tissues, might promote health in the precancerous tissue."

Appleton recognizes this possibility but says "there's no evidence that supplementing with glutathione, even intravenously, is in any way going to make any cancer worse. In fact, the evidence we have suggests the opposite. It suggests that glutathione and other antioxidants, far from interfering with the activity of chemotherapy, appear to reduce side effects without decreasing efficacy and may, in fact, improve the efficacy of the chemotherapy in fighting cancer."

Bounous says his research has demonstrated that taking Immunocal actually lowers glutathione in cancer cells while increasing it in normal cells. As a result, the cancer cells are more vulnerable to chemotherapy, and the normal cells are protected.

The upshot? The experts disagree on who should take glutathione or its precursors. Bounous says everyone should take it in order to optimize overall health. Appleton would reserve it for people with cancer. Jones says it might only prove beneficial for those who eat poorly and are thus unlikely to be getting much glutathione or its precursors in their diet.

They all acknowledge that people with severe diseases known to be associated with low glutathione levels, such as AIDS, may well benefit from the supplement, although there is no proof to this effect.

For her part, Myriam Abalain is still taking Immunocal and feeling fine. "I'm doing pretty good now," she says. "I'm in better shape than ever!"
