N-Acetyl-cysteine [NAC]
N-Acetyl-cysteine (NAC) is a supplement derived from the amino acid L-cysteine. It has a variety of potential health benefits, including:
- Acting as an antioxidant: NAC helps replenish glutathione, the body's master antioxidant, which protects cells from damage caused by free radicals.
- Thinning mucus: NAC can help loosen thick mucus in the airways, making it easier to cough up and improving respiratory function. This is why it's sometimes used to treat conditions like bronchitis and chronic obstructive pulmonary disease (COPD).
- Supporting brain health: NAC may play a role in protecting brain cells and improving cognitive function. Some studies suggest it may be beneficial for people with conditions like Parkinson's disease and Alzheimer's disease.
It's important to note that while NAC has been shown to be safe and well-tolerated in most people, it can cause side effects like nausea, vomiting, and diarrhea. It's also important to speak with your doctor before taking NAC, especially if you have any underlying health conditions or are taking other medications.
NAC is available as a dietary supplement and is also a medication that is used to treat acetaminophen poisoning. However, it's important to remember that supplements are not regulated by the FDA in the same way that medications are, so it's important to talk to your doctor before taking any supplements.
