Amino acids are the building block of proteins in the body.

Heartburn, nausea, vomiting, and digestive upset.

Integrative medicine practitioners suggest the glutathione increase might help prevent and manage some health conditions. These include:

  • Acetaminophen poisoning
  • Lung disease, including chronic obstructive pulmonary disease (COPD)
  • COVID-19 and other viral illnesses
  • Heart disease
  • Male infertility
  • Polycystic ovary syndrome
  • Mental health disorders
  • Neurological disease
  • Inflammatory bowel disease
  • Obstructive sleep apnea

Some healthcare providers suggest that NAC could have benefits against certain types of cancer, liver diseases such as cirrhosis or hepatitis, kidney disease, lupus, and more.


NAC has the agency's stamp of approval for treating Tylenol (acetaminophen) poisoning. 


Some studies have looked into the benefits of NAC in people with lung diseases such as:6

  • Chronic bronchitis
  • COPD
  • Cystic fibrosis


COVID-19 and Other Viral Illnesses

Due to the antioxidant and anti-inflammatory characteristics of NAC, it has been used in clinical practice for people hospitalized with COVID-19.

A 2021 study published in Infectious Diseases looked at the effects of NAC supplementation. Researchers said taking 600 mg NAC orally (by mouth) twice daily for 14 days led to:

  • Reduced disease progression
  • Reduced need for intubation (a breathing tube)
  • Fewer deaths


Some evidence also supports using NAC to help treat:

  • Influenza (the flu)
  • Respiratory syncytial virus (RSV)
  • Tuberculosis
  • Heliobacter pylori (H. pylori) infection


Heart Disease: Proponents of NAC say it may help lower the risk of heart disease by reducing oxidative stress on the heart. Oxidative stress occurs when an imbalance of free radicals (unstable molecules) damages your body's cells and tissues.

In research, daily use of NAC reduced hypertension (high blood pressure), which is a significant contributor to atherosclerosis (plaque build-up in the arteries).


Male Infertility

Polycystic Ovary Syndrome


Mental Health Disorders

NAC may play a role in treating mental health conditions related to inflammation and dysregulation of the neurotransmitter (brain chemical) glutamate.

Preliminary results have mostly been inconclusive, but some research suggests NAC supplements may be an effective add-on treatment for:14

  • Mood disorders, including major depressive disorder and biopolar disorder)14
  • Obsessive-compulsive disorder (OCD)14
  • Schizophrenia15
  • Substance abuse disorders, especially involving cocaine and cannabis (marijuana)


Neurological Diseases

NAC may have a use as an add-on treatment for some neurological conditions, including:6

  • Parkinson's disease
  • Alzheimer's disease/dementia
  • Multiple sclerosis
  • Peripheral and diabetic neuropathy
  • Stroke rehabilitation


Sleep Apnea: Causes you to stop breathing for short periods while you sleep. It's considered a cause of inflammation and a risk factor for high blood pressure, stroke, and heart disease.

Some small studies have suggested that NAC supplements may help improve nighttime breathing and reduce snoring in people with sleep apnea.


Cysteine Deficiency

Since cysteine is made in the body and found in high-protein foods, deficiency is rare.

However, if you're a vegetarian or vegan, you may be at risk of cysteine deficiency, especially if you don't eat a lot of cysteine-rich plants.
