NAC is a potent supplement that strengthens the immune system, reduces inflammation, and increases glutathione—the body’s most powerful antioxidant, known to suppress viral replication. It supports natural detox by aiding liver and kidney function and helps regulate glutamate, a key neurotransmitter. These effects may improve brain health and benefit neurological conditions like Alzheimer’s and Parkinson’s. NAC is an excellent choice for boosting immunity and overall wellness.
