Quick Overview

What is it?

NAC is N-Acetyl-Cysteine, the acetylated version of the sulfur amino acid, l-Cysteine. Each capsule contains 600 mg of NAC. Inert ingredients include rice flour, water, and gelatin

NAC is a very potent antioxidant, chelating agent, and the precursor of one of the body's primary protective agents, Glutathione.


L-Cysteine is converted into toxic l-Cystine without Vitamin C. Vitamin C should always be taken with NAC.

L-Cysteine is also an excitotoxin in the brain which can seriously damage brain cells. In fact, it is thought by some that L-Cysteine is the culprit in neuromuscular diseases such as ALS, MS and Alzheimer's. People with those conditions either metabolize the amino acid incorrectly or have it catalyzed by such metals as Aluminum. L-Cysteine excitotoxicity is completely blocked by Zinc which should also always be taken with it.

This is a sulfur based compound and may emit an odor.

Suggested Use
