The Powerful Supplement You've Probably Never Heard Of

The Powerful Supplement You've Probably Never Heard Of

N-ACETYL CYSTEINE (or NAC)

I first learned of NAC when I was a young pharmacy intern working at a hospital in Toronto.?NAC was used intravenously to treat patients with acetaminophen overdose, and it was also prescribed via inhalation to help patients clear excess mucous from their lungs. As a result, I was quite surprised to learn that this drug has been available for decades as an over-the-counter dietary supplement. (1)?

In fact, NAC is a powerhouse supplement in the functional medicine world.

NAC is a powerhouse supplement in functional medicine

Here’s why…

The body is under constant attack from free radicals, which are unstable molecules created through biochemical reactions in the body or from environmental insults. Free radicals can damage DNA and other components of cells, eventually leading to tissue aging and disease. NAC is an antioxidant that helps get rid of these free radicals. It does this by directly removing them, and more importantly, by boosting the production of glutathione.?

Glutathione is found in every cell of the body and is often referred to as the body’s “master antioxidant”. It is made up of 3 amino acids: glycine, glutamine, and cysteine, the last of which is often in limited supply. NAC provides a source of cysteine and thereby increases production of this powerful, disease-preventing antioxidant.

In addition to its role as an antioxidant, NAC also:

  • Reduces inflammation through suppression of NF-kB activation
  • Promotes growth and protection of nerve cells
  • Supports removal of drugs, chemicals, and heavy metals from the body
  • Breaks down excess mucous
  • Modulates the activity of the neurotransmitters dopamine and glutamate, and
  • Supports production of nitric oxide for blood vessel dilation

(2-4)

NAC shows promise for a variety of conditions

As a result of this myriad of actions in the body, NAC has shown promise in a wide-range of conditions either alone, or as an adjunct to conventional therapies.

These include:

  • Male and female infertility
  • COPD exacerbations
  • Drug addiction relapse
  • Parkinson’s Disease
  • Traumatic brain injuries/concussion
  • Depression
  • Schizophrenia
  • Chronic kidney disease
  • Acne
  • Dry eye
  • Retinitis pigmentosa, and more.

(2-10)

Overall, it’s a very safe supplement with minimal side effects, the most common being nausea and vomiting.?

If you’re interested in trying it out, be sure to consult with a qualified practitioner as there are varying dosages and dosage forms, and a potential for drug interactions. (11)?

Endnotes and References:?

1. Although NAC has been available as a dietary supplement for quite some time, the FDA had recently considered banning its sale owing to its original status as a drug. However, as of August 2022 the FDA is considering a rule to allow ongoing sale of NAC, provided the products do not violate the Federal Food, Drug and Cosmetic Act. (2) I’ve got my fingers crossed that the FDA doesn’t ultimately decide to remove this valuable supplement from the OTC market.?

Note that NAC has been used for decades as an IV prophylactic treatment to prevent kidney injury due to IV contrast before CT scans. The name is Mucomyst. It is OTC as an oral supplement because it is a variation of the amino acid Cysteine. That’s it, just an amino acid with an acetyl group. But as you said, the body readily uses it to produce glutathione, and NAC alone has some detoxification properties. My question is where can I find literature about NAC’s protective effects on nerve cells? Thanks!
