What is NAC?

Posted 22 Jul '16

N-Acetyl Cysteine, or NAC, is such an effective reliever of coughing, wheezing, and phlegm brought about by colds or flu, it comes as a shock that it is not that popular as prescription medication by doctors, given that NAC is cheap and is available as a generic medication. At least it is one used by naturopaths and nutritionists to help patients!

NAC comes from Cysteine, an amino acid, which is regarded as the building block of proteins. NAC is the preferred form of Cysteine since it is produced within the body, and thus cannot be obtained from food sources. It plays a very important role to the body’s overall health. Here are some of the major uses of NAC in the body:

  1. NAC helps your liver. It is especially effective in clearing the liver of any heavy metal toxicity. This is due to NAC being a precursor to glutathione, which aids in liver detoxification and protects against liver damage or acute liver failure.
  2. NAC is an major antioxidant. As people age, cell damage and cell death increases due to oxidation. Studies have shown N-Acetyl Cysteine to have the ability to protect from, and prevent cell death, or apoptosis. It is even widely recommended to athletes who has experienced high oxidative stress brought about by strenuous activities.
  3. NAC as a mucolytic. N-Acetyl Cysteine is an effective mucolytic (mucous buster) by breaking down mucoproteins, thus clearing the nasal and bronchial passageways of mucus. It is a great one for congestion in the lungs and sinus.
  4. NAC helps strengthen the immune system. It is caused by the stimulation effects of glutathione that activates and proliferates T cells in the immune system. T cells are produced by the thymus gland and very important for fighting infections in the body.
