Nac is the precursor to glutathione, a powerful antioxidant that scavenges free radicals that damage cells. Nac can help our bodies function properly by protecting our organs at a cellular level from chemical stressors. N-Acetyl Cysteine 600mg is an occurring antioxidant in the body and supplementing with it at our recommended dose is a safe way to support organ and tissue health during almost any time of life, including pregnancy. Clinical trials have demonstrated that, due to its powerful antioxidant effects, Nac supplementation can support full-term gestation in certain women, thereby supporting a healthy pregnancy for mother and baby. Our N-acetylcysteine 600mg Supplement is 100% vegan and cruelty-free. We are also one of the only supplement brands to offer vegan-friendly plant-derived capsules. (Please note that our Nac is high-quality and therefore has a pungent, sulphury smell this is a sign of quality and not a reason for concern).
