Get expert advice

NAC (N-acetyl cysteine) is a form of the amino acid cysteine and the building block your body uses to make glutathione, one of its main antioxidants. That’s why people reach for it most often for everyday antioxidant and immune support, and to help support normal liver function. You’ll find NAC here in the standard 600 mg capsules, higher-potency 900–1000 mg options, powders, effervescent tablets, and liposomal liquids, plus formulas that pair it with glycine, selenium, or quercetin. Shipped across Canada from our Ontario warehouse.

    What NAC is and what people take it for

    NAC is made from the amino acid L-cysteine and acts as a precursor to glutathione — meaning your body uses it as a raw material to make one of its key antioxidants. Most people take it for everyday antioxidant and immune support, and to help support normal liver function. Because glutathione plays a role across so many cells, NAC has become one of the more popular single-ingredient supplements.

    Forms and potencies

    • 600 mg capsules — the standard, well-studied amount and the most common way people take NAC day to day.
    • 900–1000 mg — higher-potency capsules and tablets for those who want a larger single dose.
    • Powder — flexible dosing; mixes into water or a smoothie.
    • Effervescent tablets — dissolve in water if you’d rather not swallow capsules.
    • Liposomal liquid — the NAC is wrapped in a thin fat layer to support absorption.
    • Paired formulas — some combine NAC with glycine, selenium, or quercetin.

    How to choose

    The right NAC comes down to the dose and format that fit your routine. A standard 600 mg capsule suits most people; powders and effervescent tablets help if you don’t like capsules or want to adjust the amount; liposomal is an option if absorption is your main interest. Check the per-capsule amount so you know what a serving actually delivers.
