About this item
Product details
N-Acetyl-l-Cysteine (NAC) is a derivative of the amino acid l-cysteine. NAC has a high affinity for lung tissue, which it supports through mucolytic and antioxidant action. NAC supports tissue levels of glutathione, a key component of the antioxidant defense system*. At Pure Encapsulations, we're dedicated to providing nutritional supplements you can trust. That’s why our products are formulated using high quality, pure ingredients FREE FROM unnecessary additives and many common allergens, and backed by verifiable science. Everything you need and nothing you don't, that’s goodness encapsulated. When developing our products, we work in close collaboration with leading medical professionals and nutritional experts to create premium dietary supplements that you can feel good about. We source high-quality ingredients from the best suppliers, conduct research and clinical trials to confirm efficacy and safety, and undergo additional testing by accredited and cGMP-certified laboratories to ensure product purity and potency. We also believe in transparency, so every ingredient we put into our products, even if it’s just a trace amount, is listed on the label. If there’s an ingredient sourced from a possible allergen—we call that out too.
