Antioxidant Properties

NAC has an important role in antioxidant production. This amino acid is one of the major ingredients needed to replenish intracellular levels of the body’s most powerful antioxidant, glutathione.

Glutathione is absolutely essential for proper detoxification and good health. It is produced in the liver and protects cells from the onslaught of free radicals that we encounter daily from food, alcohol, medication, stress, and the environment. It’s known that free radical damage results in cellular inflammation, which plays a significant role in the development of chronic health conditions like arthritis.

Taking NAC will increase glutathione levels, reduce oxidative damage, and encourage detoxification.

Immunity

NAC’s glutathione-restoring properties make it a promising immune-boosting supplement. Studies have found that it significantly increases immune function.

A 2008 study on postmenopausal women found that NAC supplementation resulted in the long-term strengthening of the immune system and reduced the risk of infection.

Mental Health

NAC helps promote better overall mental health. A 2016 review of five studies found that supplementing with NAC can help promote better mood and overall function. These benefits are due to NAC’s influence on dopamine and glutamate levels in the brain, as well as its ability to increase antioxidant levels and reduce oxidative damage and inflammation in the brain.

Heart Health

NAC is a super nutrient when it comes to promoting heart health. We know that free radical damage leads to inflammation, which is a major risk factor for heart issues. Therefore, NAC may promote better heart health by increasing glutathione levels and reducing free radical damage. A 2015 study found that NAC supplementation lowered markers for heart issues, including homocysteine levels and blood pressure.
