Pure Encapsulations NAC (n-acetyl-l-cysteine)

Description

NAC, short for N-acetyl-L-cysteine, is an amino acid derivative your body uses to make glutathione, one of its primary internal antioxidants.* Supplementing with NAC is a common way to support the body’s glutathione production and its overall handling of everyday oxidative stress.*

Because glutathione plays a role in cellular defense throughout the body, NAC is often included in broader antioxidant routines rather than used for one specific purpose. It pairs reasonably well with other antioxidant nutrients like vitamin C or E if you’re building out a more complete daily stack.

If you’re not sure whether NAC fits alongside what you’re already taking, our clinical team can help you sort out dosing and timing, particularly if you’re on other medications, since NAC can interact with certain prescriptions.
