One of NAC’s most important jobs is to help your body replenish its glutathione stores. As one of your body’s most potent antioxidants, glutathione helps to get rid of cell-damaging free radicals.
Reducing oxidative stress can help to lower your risk of developing chronic conditions such as heart disease, diabetes, and infertility.
NAC does more than just aid in the production of glutathione. Other benefits of the nutrient include:
Detoxification of the Liver and Kidneys
NAC plays a role in the detoxification of your kidneys and liver. It can help to prevent potential side effects of drugs and environmental factors — such as exposure to heavy metals — that may impact these organs.
In instances of acetaminophen overdose, doctors often give NAC intravenously to reduce damage to the liver and kidneys.
Improved Symptoms of Respiratory Issues
NAC supplements can help those with chronic obstructive pulmonary disease (COPD) by improving symptoms and managing lung decline. The supplement can also help to decrease the severity of wheezing and coughing in people with bronchitis.
Improved Immune Health
There aren’t many studies on NAC and the immune system, but current research suggests that it and glutathione may help to improve your immune function. Most of the studies focus on NAC and people with human immunodeficiency virus (HIV).
