N-Acetylcysteine (NAC) is a supplement form of the amino acid cysteine, known for its potent antioxidant properties. It's often used for its various health benefits, including supporting liver function, promoting detoxification, and boosting the immune system. NAC plays a role in replenishing levels of glutathione, one of the body's most powerful antioxidants, which helps protect cells from oxidative stress and damage.
