NAC and Cancer

According to various clinical studies regarding cancer, N-acetylcysteine can significantly reduce the ability of the tumor to invade the surrounding tissues. One particular research showed that metastases can be decreased by about 80% when treated with N-acetylcysteine. It is also used in the prevention of colon cancer. 62 individuals participated in a preliminary double blinded placebo controlled study. These patients had polyps removed from their colon. Polyps are closely associated with the development of cancer. The benefits of N-acetylcysteine in the treatment of cancer were evaluated by rectum biopsy. Results show that the group who took N-acetylcysteine at 800 mg daily for a period of 12 weeks has more normal cells in contrast with the placebo group.


Immunologically, N-acetylcysteine can enhance the production of T-cell. As a matter of fact, AIDS patient are deficient with glutathione and N-acetylcysteine. N-acetylcysteine can inhibit the replication of HIV in vitro and can enhance the ability of some cells of the immune system to kill pathogens.

A study involving 45 patients was done at Standford University. They were given 3200 mg to 8000 mg of N-acetylcysteine daily for a period of 6 weeks and were likely to survive for approximately 2 years in contrast with those who did not take N-acetylcysteine. The results of this study had suggested that N-acetylcysteine can slow down the drop of CD4+ in HIV patients and increase the levels of CD4+ cells in healthy individuals.

NAC and Acetaminophen (Tylenol) Poisoning

N-acetylcysteine helps prevent liver damage caused by acetaminophen toxicity. Hospitals actually use NAC for the treatment of acetaminophen poisoning.

NAC as a Mucolytic Agent

N-acetylcysteine is known to be an excellent mucolytic agent. It helps keep the membranes of the respiratory system moist thus protecting the body from irritants like dust, dry air and air pollutants.
