N-Acetyl Cysteine

What is N-Acetyl Cysteine?

N-Acetyl Cysteine (NAC) is a modified form of the amino acid cysteine, where an acetyl group has been attached to its structure. It's commonly used as a dietary supplement and also has medicinal applications due to its various potential health benefits.

Health benefits of using N-Acetyl Cysteine

1. Antioxidant Properties:

NAC is a precursor to glutathione, one of the body's most important antioxidants. It helps in the regeneration of glutathione, supporting the body's defense against oxidative stress caused by free radicals.

2. Respiratory Health:

It's used in clinical settings to assist in loosening and thinning mucus in the airways, making it easier to clear for people with respiratory conditions like chronic bronchitis, COPD (chronic obstructive pulmonary disease), or cystic fibrosis.

3. Liver Health:

NAC has been studied for its potential to protect the liver from damage caused by various toxins, including acetaminophen overdose and certain pollutants or drugs.

4. Mental Health:

Some research suggests that NAC might have benefits for mental health conditions such as obsessive-compulsive disorder, depression, bipolar disorder, and addiction. It's believed to modulate neurotransmitter levels and potentially reduce symptoms in these conditions.

5. Immune Support:

Due to its antioxidant properties, NAC might also support the immune system by reducing oxidative stress and inflammation.


NAC supplements are available in various forms such as capsules, tablets, or as a solution. They are generally considered safe when taken in appropriate doses, but side effects such as nausea, vomiting, or diarrhea can occur, especially at higher doses.
