About NAC and glutathione

N-acetyl-L-cysteine (NAC) is a modified form of the amino acid cysteine and one of the most researched precursors to glutathione, the body’s most abundant intracellular antioxidant. Glutathione is formed in the body’s cells from three amino acids: cysteine, glycine and glutamic acid. Of the three, cysteine is the one in shortest supply, which is why it is the one supplemented.

NAC has been studied in several hundred published scientific studies. Research published in journals such as Antioxidants & Redox Signaling and Free Radical Biology & Medicine has studied NAC for its specific role in mucolytic activity (thinning mucus) and delivers 900 mg per capsule. It is one of the few substances that effectively raises intracellular glutathione levels when taken orally.

NAC is often combined with glycine, the third amino acid in glutathione, since cysteine and glycine are the two the body runs short of. Designs for Health’s NAC is a single-ingredient capsule with no fillers, which is what makes it straightforward to combine with anything else.

Who is NAC for?

NAC suits you if you want to support the body’s glutathione and antioxidant status. It is popular among biohackers, the longevity-focused and athletes who want NAC as a single amino acid product in a high dose.

What is glutathione and why does it matter?

Glutathione (GSH) is a tripeptide built from cysteine, glycine and glutamic acid, and is the body’s most abundant intracellular antioxidant. Cysteine is the amino acid of the three that the body has least of, and NAC is a stable, well-absorbed form of it. The product is not a replacement for medical treatment.

What is the difference between NAC and glutathione supplements?

Glutathione as a direct supplement has lower bioavailability because it is largely broken down in the digestive tract. NAC is a building block the body uses to produce glutathione in the cells where it is needed. NAC is therefore often considered a more effective way to raise intracellular glutathione levels.

When during the day should I take NAC?

NAC can be taken at any time. An empty stomach gives the best absorption, but it also works with a meal. Many prefer the morning or lunchtime.

How long does one jar last?

One jar contains 120 capsules. At 1 capsule a day it lasts 4 months, at 2 capsules a day 2 months.

Can I combine it with other antioxidants?

Yes, NAC is often combined with alpha-lipoic acid, glycine, B vitamins (particularly B6 and folate) and magnesium. Consult a nutritional therapist to tailor a protocol.

Where and how is the product made?

NAC is made in the USA by Designs for Health in a facility following cGMP standards regulated by the FDA. The raw material undergoes third-party testing for identity, potency and the absence of heavy metals.
