Throughout the last couple of years we’ve seen supplements rise and fall in popularity. But sometimes they get in the spotlight and stay there. NAC is an example of this. The thing is NAC isn’t new to dietary supplements, so why now? In this post, we’re going over the top questions on NAC and what it does!

What Is NAC?

NAC or N-acetyl cysteine is an amino acid precursor of L-cysteine, a semi-essential/conditionally essential amino acid. (1)

There are 20 amino acids that make up proteins in the human body. These amino acids are categorized by their biosynthesis processes as essentials, semi-essential, or nonessential. Out of 20, only 9 amino acids make up the essential amino acid group.  These amino acids cannot be synthesized in our bodies, meaning we need to supplement them into our diets. Whereas semi-essential amino acids, like cysteine, typically run low during infancy or when sick/injured. The remaining amino acids can be synthesized  in the body and therefore non-essential. (2)

How Does NAC Work?

NAC is a powerful antioxidant that can stimulate glutathione biosynthesis. This results in supporting your body neutralizing free radicals that can damage cells and tissues in your body. Which is essential for promoting immunity and longevity. (3

NAC VS Glutathione:

Unfortunately, taking glutathione by mouth does not appear to effectively improve its biosynthesis. This is likely due to the bioavailability being low and how it may be broken down by enzymes in the stomach. (4)MAAC 10 Formulas NMN

NAC VS NAD:

NAD (nicotinamide adenine dinucleotide) is derived from Nicotinamide Riboside (NR). Where NR is form of Niacin (vitamin B3).  Similar to NAC, it may help with improving cognitive health. But NAD may also help reduce blood pressure and lower cholesterol.†

Is It Banned?

Its complicated, but as of February 2022, no. Earlier in the summer of 2020, the FDA sent out warning letters to companies claiming that NAC is not a dietary supplement. As a result, industry associations like the Natural Products Association (NPA), the Council for Responsible Nutrition (CRN) and the American Herbal Products Association (AHPA) filed citizen petitions. (5,6)

Their defense indicated that NAC meets the definition of a dietary supplement and was marketed in the U.S. food supply since 1991, before the drug-exclusion clause became law. But instead of affirming that NAC is a lawful dietary ingredient, the FDA instead said it will “continues to evaluate both citizen petitions”. (5)

So where does that leave us?

NAC may become more difficult to find as some suppliers have stopped producing it, but it is still available for purchase!

Section Divider: NAC Benefits

 Benefits:

Because of it’s antioxidant properties, NAC can be beneficial for health conditions caused by oxidative stress. But in general, NAC’s potential benefits are extensive.(1,7,8)

They include:

  • Powerful Antioxidant
  • Stimulants Glutathione Production
  • Support Healthy Lungs, Gut, Brain, Liver, And Kidneys
  • May Reduce Symptoms Related To The Flu
  • May Improve Fertility In Both Men And Women
  • Could Help Autoimmunity By Reducing Inflammation
  • Helps Prevent Oxidative Damage

As you can imagine from the FDA case, there are medicinal uses for NAC†. (9)

This includes:

  • Treat acetaminophen (Tylenol) poisoning
  • Dissolve/loosen mucus caused by some respiratory disorders
  • Treat polycystic ovary syndrome (PCOS)

Can NAC Help With COVID?

One study indicates that supplementing with 600 mg of NAC twice daily for 14 days may assist with reducing the diseases progression and reduce the need for intubation. However, more research is needed to evaluate the benefits of NAC.* (10)

*We do not recommend to take any dietary supplement such as NAC in replacement of medical treatment for respiratory conditions like COVID-19.
