NAC is an incredible antioxidant with numerous health benefits. It may help with mood disorders, sleep, infections, and inflammation. NAC protects the brain, gut, kidneys, liver, and lungs. It helps with most states of increased oxidative stress, which underlie chronic health problems. We list and describe all the benefits of NAC, along with dosage and side effects.

What Is NAC?

NAC is short for N-Acetylcysteine. NAC is transformed into cysteine in the body. Cysteine is the most important amino acid that makes glutathione, the body’s strongest antioxidant [R].
Cysteine levels determine how fast glutathione is made, NAC is essential in replenishing levels of this antioxidant in the body. Glutathione removes free radicals from cells and activates detox pathways [R, R].

NAC also falls under the category of “thiols”, antioxidant substances that contain the sulfur group. NAC is a thiol thanks to the sulfur-containing cysteine. In fact, this sulfur in cysteine is essential for the antioxidant activity of glutathione [R].
NAC can directly fight free radicals, acting as a powerful antioxidant [R].
Its antioxidant effects protect DNA, cells, tissues, and organs from damage, inflammation, and harmful substances [R].
NAC can also break down and soften mucus, which can improve lung diseases [R].
NAC has been thoroughly researched. The number of clinical, animal, and cell studies that explored the benefits of NAC are almost impossible to list. Close to a thousand clinical trials of NAC exist alone!

Health Benefits of N-Acetyl Cysteine

1) NAC Protects the Liver
NAC boosts the antioxidant glutathione, the highest amount of which is in the liver. This helps explain why NAC has such a strong effect on protecting the liver from inflammation, drug poisoning, and serious liver diseases.
Liver inflammation
If the liver is damaged by any factor, inflammation and oxidative stress always rise. NAC can protect the liver by reducing inflammation and increasing antioxidant reserves.
NAC reduced liver damage in 85% of all cases, according to a review of 68 pre-clinical and 1 clinical study. It could protect the liver from factors such as excessive alcohol or environmental pollutants [R].
NAC helped increase liver function better than glutathione in one study of 75 patients with Hepatitis B. The patients received very high doses of NAC (8 g/day) as injections for almost a month [R].

Acetaminophen poisoning
N-Acetyl Cysteine has been used as an antidote to acetaminophen poisoning for over 50 years. Commonly-used painkillers (such as Tylenol and Vicodin) contain acetaminophen, which can damage the liver and even cause liver failure in high doses. It’s the most common cause of serious, sudden, liver damage [R, R].
N-Acetyl Cysteine is the most effective drug that can prevent serious liver damage from acetaminophen and increase survival, according to several studies of over 400 patients. NAC also has very few side effects [R, R].
Serious Liver Damage
Sudden, life-threatening liver damage can rarely also be caused by factors other than acetaminophen: various drugs, toxins, or hepatitis.
NAC helped protect the liver in 80 such cases (RCT), increased their survival and shortened their hospital stay. The patients with liver damage from drugs experienced the best results [R].

NAC has been studied a lot in the intensive care units, as a possible way to reduce organ damage before and after surgery. It helped protect the liver in 70 patients with lung disease, given shortly before heart surgery. 900 mg/day of NAC was given for a week [R].
NAC also reduced liver damage when given shortly before liver surgery in a study of 48 people (DB-RCT) [R].
2) NAC Fights Free Radicals
Oxidative stress can damage cells and is increased in many chronic diseases, malnutrition, and toxin exposure.
NAC can replenish glutathione, protecting cells and organs that are under oxidative attack [R].
In several studies of 43 healthy men in total (RCTs), 1,200 mg of oral NAC daily increased antioxidant status after just 8 days. It increased the levels and activity of glutathione enzymes and reduced oxidative damage markers by more than 30%. NAC could also increase red blood cells and markers of their function and size (erythropoietin, hemoglobin, hematocrit, MCV) [R, R]
Oral glutathione has poor bioavailability, and taking NAC is one way to circumvent this. Oral NAC (200 mg of power/day) increased glutathione and antioxidants better than oral glutathione in a study of 20 people. But sublingual glutathione had stronger effects than both NAC and oral glutathione after 3 weeks [R].
In African countries, children with severe malnutrition do not have good chances for survival. NAC could increase their recovery and survival by raising their glutathione levels in a pilot study. These children received up to 1,200 mg NAC/day in addition to standard treatment. Since NAC is cheap and safe option to aid their recovery by boosting antioxidant levels [R].
3) NAC Reduces High Homocysteine and Heart Disease Risk
B vitamins only somewhat help reduce high homocysteine, while NAC can lower both homocysteine and high blood pressure. Normalizing homocysteine could help prevent heart disease and other chronic health problems [R].
In two studies of 82 men in total (DB-RCTs), oral NAC (1,800 mg/day) lowered homocysteine and blood pressure while increasing antioxidant status over 4 weeks. It had an equally beneficial effect in men with high and normal blood lipids, and in both smokers and non-smokers [R].
In another study of 60 people with heart disease, NAC (600 mg/day) lowered homocysteine levels and improved blood vessel health over 2 months [R].
4) NAC Protects from Toxins and Pollutants
Glutathione is not stored only in the liver. By increasing levels of glutathione throughout the body and combating oxidative stress, NAC can protect from many toxins and pollutants.
Heavy Metal Exposure
NAC may be a safe alternative for chronic lead toxicity.
NAC reduced lead levels, increased glutathione and antioxidant enzymes in red and white blood cells in 171 workers exposed to lead after 3 months. It reduced both lead levels and homocysteine The beneficial daily dose was 400-800 mg per day [R, R].
The combination of NAC and zinc could also protect from mercury toxicity in rats, preventing the accumulation of mercury in the liver and blood.
