As discussed below, evidence suggests that N-acetylcysteine (NAC) may reduce cardiovascular disease and dementia risk by lowering homocysteine, improve cognitive function, protect against oxidation, provide cancer protection, protect the liver and kidneys from toxins, reduce the severity of influenza, and improve athletic performance.

NAC has been used traditionally used in medicine as a drug to break up mucus in the lungs and as the antidote to acetaminophen overdose. NAC is able to protect the liver from the toxic effects of acetaminophen largely through its ability to replenish reduced glutathione. Glutathione is one of the body’s most powerful and most plentiful antioxidant molecules. Glutathione is created from the combination of cysteine, glycine, and glutamate and is critical for the health of all cells and, therefore, all organs and organ systems. Not surprisingly then, modern medicine is currently interested in using NAC for a number of conditions as mentioned in a recent American Family Physician abstract:

"Other applications for N-acetylcysteine supplementation supported by scientific evidence include prevention of chronic obstructive pulmonary disease exacerbation, prevention of contrast-induced kidney damage during imaging procedures, attenuation of illness from the influenza virus when started before infection, treatment of pulmonary fibrosis, and treatment of infertility in patients with clomiphene-resistant polycystic ovary syndrome. Preliminary studies suggest that N-acetylcysteine may also have a role as a cancer chemopreventive, an adjunct in the eradication of Helicobacter pylori, and prophylaxis of gentamicin-induced hearing loss in patients on renal dialysis.1

As you can tell, NAC supplementation may offer numerous health benefits. Let us explore just a few of the most universal possibilities.

In regards to the influenza virus, only 25% of influenza infected subjects that were taking 600mg of NAC twice daily for 6 months experienced influenza symptoms while 79% of those infected subjects not taking NAC experienced symptoms.2

As for cancer prevention, the antioxidant activity of NAC and glutathione logically may provide protection against many cancer types, however the research literature is largely restricted to discussing the potential preventive effects against lung cancer and colon cancer.3,4,5

NAC has been shown to lower serum homocysteine levels in several studies.6,7 Homocysteine is an amino acid that has been associated with cardiovascular disease and dementia.8,9,10,11,12,13,14,15 It can be easily measured by a physician using blood tests and the dose of NAC may be adjusted according to the results. The evidence, therefore, supports the use of NAC in an effort to prevent and treat cardiovascular disease and dementia, but long term outcome based studies are still lacking to evaluate efficacy. Several studies, however, demonstrate that NAC can help to improve cognitive performance in patients with Alzheimer’s disease over a 6 to 12 month period.16,17,18

Finally, NAC has shown promise in enhancing exercise performance and endurance. Intense exercise produces free radicals in the muscle cells which contribute to fatigue. High doses of intravenous NAC appears to help control the accumulation of these free radicals and enhance endurance. As a consequence, NAC also led to an increase in VO2max.19,20,21

Each capsule of Cycle-Breakers® NAC contains 750mg. The recommended dose is 1-2 capsules per day (750-1500mg) or as directed by your healthcare provider.
