N-Acetyl-L-Cysteine (NAC) Bulk Powder is a high‑purity, acetylated derivative of the amino acid L‑cysteine, widely recognized as a potent antioxidant and mucolytic agent in the dietary supplement, pharmaceutical, and functional nutrition industries . As a stable, versatile bulk ingredient, NAC serves as a direct precursor to glutathione – one of the body's most critical endogenous antioxidants – supporting cellular defense against oxidative stress, liver detoxification, and respiratory health . Manufactured under strict GMP and ISO standards, our NAC powder offers consistent assay (≥98% – 101%), low heavy metal content, and excellent solubility, making it an ideal choice for capsules, tablets, powder blends, drink mixes, and custom premix formulations . Available with flexible MOQs (from 1kg lab samples to tonne‑scale bulk), customizable particle sizes, and full documentation including COA, MSDS, stability data, and Halal/Kosher certifications, our NAC bulk powder is engineered to meet the rigorous quality and compliance demands of global B‑end customers
