N-acetyl-L-cysteine is also known as NAC. It’s a basic building block of a peptide called glutathione – nicknamed the “mother of all antioxidants” by Mark Hyman MD. Glutathione (GSH) comprises three key amino acids. Researchers into human longevity think it’s crucial to our health. So much so in fact that the levels of GSH our cells contain is being used to predict how long we’ll live.
If you know how important antioxidants are to your good health then you’ll get some idea from all this how powerful NAC may be for you.
This article in Vitality magazine lists the amazing benefits of N-acetyl-L-cysteine. They encompass:
- Cardiovascular system benefits
- Neurological benefits
- Immune system benefits
- Detoxification and the liver benefits
- Respiratory tract benefits
- Stomach, intestinal and kidney benefits
- Psychiatric and addiction benefits
- Athletic and anti-aging benefits
Now let’s look at some of them in more detail.
The immune system and respiratory tract
There can’t be many of us that couldn’t use some extra help with our immune systems. In the winter months in particular. NAC may be of help in this area.
Support for fighting flu
It’s been shown that NAC may both lessen flu symptoms when they occur and protect from developing them in the first instance.
How does it do it? By decreasing your body’s inflammatory response, it reduces the symptoms.  NAC may also lessen the flu virus’ ability replicate itself at speed – the virus is often fought off before it gets a chance to get hold.  Indeed, one particular study demonstrated that older adults taking NAC went on to develop flu only 25 percent of the time. While a group of same age that weren’t taking it developed full-blown flu 75 percent of the time.
NAC can benefit chronic bronchitis and asthma
Chronic bronchitis is caused by an inflammation of the bronchial tubes – often a result of oxidation damage. The end result is coughing and a build of mucus in the lungs.  A build-up of mucous in the lungs trigger asthma attacks so NAC may be of help to asthmatics.
NAC may help to reduce the symptoms of chronic bronchitis by reducing radicals in the bronchial tubes. 
Assistance with chronic obstructive pulmonary disease (COPD)
COPD is a lung disease that makes breathing difficult. It comes under two main categories: chronic bronchitis and emphysema. A common cause of COPD is cigarette smoke though air pollution, chemical fumes or dust can also be to blame.  Whatever the cause, the end result is irritated, inflamed and damaged lung with narrowed airways. That’s what leads to the shortness of breath and coughing.
NAC replenishes glutathione in the lungs and so works to decrease the tissue and oxidative damage.  Oxygen therapy is a key treatment for COPD. Yet, the extra oxygen given to the patient during this process has the counterproductive effect of increasing production of toxic free radicals.  Introducing NAC may decrease the concentration of these radicals and so help improve treatment efficiency. 
The cardiovascular system
Disease of the cardiovascular system is often the result of oxidative damage to our heart tissue. We’re all familiar with the results: strokes and heart attacks etc.
In some circumstances, NAC may reduce this oxidative damage and so lower the risk of cardiovascular disease. 
Commonly used painkillers have in them a substance by the name of Acetaminophen – commonly known as Paracetamol. When taken in sufficient quantities, Paracetamol has the potential to be toxic to the liver, with liver failure a frequent result. 
NAC is a common treatment for liver failure caused in this way. It may greatly increase survival rates.  In addition N-Acetyl Cysteine has been effective in treating liver failure caused by other such factors as excessive alcohol consumption and pollutants in the atmosphere.  By replenishing levels of glutathione (GSH), NAC enhances toxic ammonia and acetaldehyde detoxification pathways. In so doing it offers an additional layer of protection for the liver and kidneys. 
It’s ideal then to help the liver with the detoxification process and support the Herxheimer reaction in cleansing programmes.
Having healthy intestines often determines our overall health. NAC, along with reducing oxidative damage, works to decrease inflammation in both tissues and in intestines.  Its demonstrated ability to improve intestinal barrier functions  comes hand in glove with its ability to limit the formation of biofilm by pathogens.  This is good news for all affected by Candida overgrowth.
