N-Acetyl Cysteine (NAC) is a powerful antioxidant and amino acid supplement known for supporting respiratory health, liver detoxification, and immune function. As a precursor to glutathione, one of the body's most important antioxidants, NAC helps protect cells from oxidative stress, reduce inflammation, and support overall wellness. It is widely used for lung health, as it helps break down mucus in conditions like chronic bronchitis and COPD. NAC also plays a crucial role in liver health by aiding in detoxification and protecting against toxins, including alcohol and environmental pollutants. Additionally, it may support brain function by promoting healthy neurotransmitter levels, making it beneficial for mental clarity and mood regulation. Commonly used for immune support, respiratory health, and detoxification, NAC is a versatile supplement for overall well-being.
