Overview

N-acetylcysteine + silibin is a combination of two active compounds—N-acetylcysteine (NAC), a well-established mucolytic and antioxidant agent, and silibin (also known as silybin or silibinin), the major active flavonolignan component of silymarin extracted from milk thistle. NAC acts primarily by replenishing intracellular glutathione stores, directly scavenging free radicals, breaking disulfide bonds in mucus to reduce viscosity, and providing hepatoprotective effects especially in acetaminophen overdose[1][2][3][6]. Silibin is known for its antioxidant, anti-inflammatory, and hepatoprotective properties; it inhibits lipid peroxidation and modulates cell signaling pathways involved in inflammation and fibrosis. The combination is used primarily for liver protection—especially in cases of acute toxic liver injury such as Amanita phalloides (death cap mushroom) poisoning—and may be considered for other indications where both antioxidant support and hepatic protection are desired.
