Key Features

• 250 veg capsules per bottle: A high-count supply that stretches over several months with the recommended 1 capsule twice daily routine.
• Vegetarian capsule and simple excipients: Uses hypromellose capsules with vegetable stearic acid and citric acid, suitable for those avoiding gelatin.
• Storage and odor guidance: Carded instructions to leave desiccant and charcoal packets in the bottle help delay oxidation and control any sulfur smell.

Who It's For

It suits people who understand NAC's sulfur nature and who will follow storage instructions to minimize oxidation and odor.

People who need precise clinical dosing under medical supervision, or those sensitive to sulfur smells who cannot tolerate any odor, may want to consult a healthcare provider or choose an alternative formulation. Pregnant or nursing individuals should seek medical advice before starting.
