N-Acetylcysteine

What is N-Acetylcysteine?

N-acetylcysteine is a form of the amino acid cysteine. N-acetylcysteine is a sulphur-based amino acid needed to make glutathione, a natural antioxidant enzyme produced in the body to fight free-radical activity. Without glutathione, your body’s immune system would be greatly compromised, and left with little defence against toxins and disease.

Some studies have shown that n-acetylcysteine can help protect the lungs from carcinogens found in tobacco smoke, protect the liver against the toxic effects of alcohol, and reduce toxic side effects of some drugs used to treat cancer. NAC has been used successfully to treat arsenic and mercury poisoning.

N-acetylcysteine is important to liver and lymphatic system health. N-acetylcysteine helps the liver produce the antioxidant glutathione, and it also produces enzymes that protect the body from disease. Because of its immune-boosting properties, n-acetylcysteine is often used to protect people with AIDS from complications related to immune system deficiency.

N-acetylcysteine is also used to protect the body from the development of other illnesses, including heart disease and cancer. The development of certain eye diseases, including macular degeneration and cataracts, may be delayed by n-acetylcysteine as well. These conditions are associated with free radical damage, which can be countered by the antioxidant properties of n-acetylcysteine.

It can be manufactured within the body, and can also be obtained through high protein foods, such as meat and eggs. Wheat, broccoli, garlic, onions and red peppers are also good natural sources of cysteine.

Side Effects and Warnings of N-Acetylcysteine

It is best to take oral N-Acetylcysteine supplements on an empty stomach. Side effects from n-acetylcysteine supplements are rare when the recommended amount is taken. However, high doses can cause gastrointestinal disturbances, nausea and vomiting.

To mitigate these or any other possible side effects, you should always seek medical advice from your personal doctor before using any N-Acetylcysteine supplements.
