Nutricost NAC Powder

Vegan NAC powder with 1,200 mg a scoop and 417 servings in a 500 g tub

This is Nutricost's NAC (N-acetyl L-cysteine) as an unflavored powder: one 1.2 g scoop gives you 1,200 mg of NAC, and there's nothing else in the tub. The 500 g size holds 417 scoops, more than a year's worth at one scoop a day.

NAC is a form of the amino acid cysteine, and your body uses cysteine to make glutathione, one of its own antioxidants (Rushworth and Megson, 2014). Nutricost sells it as a straightforward amino acid supplement, and the label marks it vegan, non-GMO, gluten-free and third-party tested.

Common questions

How much NAC is in a scoop?

1,200 mg in a 1.2 g scoop, with nothing else added. The 500 g tub has 417 scoops.

How is this different from Nutricost's NAC capsules?

Same ingredient, different form. A scoop of this powder has 1,200 mg, and each Nutricost NAC capsule has 600 mg. We carry both.

What's the difference between NAC and glutathione?

NAC is a form of the amino acid cysteine, which your body uses to make its own glutathione. Glutathione capsules give you glutathione itself. We carry both from Nutricost.

Do you carry a smaller tub?

Yes. We also carry the same NAC powder in a 250 g tub with 208 scoops.
