About Jarrow Formulas – N-A-C Sustain, 600mg – 60 tabs
Jarrow Formulas N-A-C Sustain delivers 600 mg of N-Acetyl-L-Cysteine (NAC) per tablet in a sustained-release format, designed to support a steady and prolonged availability of this important amino acid derivative. NAC is a stable, bioavailable precursor to L-Cysteine, which in turn serves as a key building block for glutathione — one of the body’s primary endogenous antioxidants. By providing a time-released dose, N-A-C Sustain aims to extend the window of support compared to standard immediate-release formulations.
Each tablet is made using vegetable-sourced excipients and is free from major allergens, making it a suitable choice for a wide range of dietary preferences, including vegans and vegetarians. The coating system uses hydroxypropylmethylcellulose and microcrystalline cellulose, ensuring the tablet is 100% plant-based from core to shell.
Jarrow Formulas is a science-based supplement brand with a long-standing commitment to quality, purity, and transparent formulation. N-A-C Sustain is manufactured to meet rigorous quality standards, providing you with a reliable and well-formulated NAC supplement.
