NAC (n-acetyl-cysteine)

NAC As An Antioxidant N-Acetylcysteine (NAC) is a naturally occurring antioxidant found in allium vegetables, such as garlic, onion, leeks, chives, and scallions. NAC is also a precursor to the amino acid L-cysteine, and consequently, to glutathione, the body’s master antioxidant. Because NAC naturally replenishes glutathione inside the body, it can be especially important during the aging process since glutathione production slowly decreases as we age, putting us at increased risk of oxidative damage, and the diseases associated with oxidative stress. Seniors especially benefit from a boost of their glutathione levels. Read more >

NAC Supplement

N-Acetylcysteine (NAC) is a naturally occurring antioxidant found in allium vegetables, such as garlic, onion, leeks, chives, and scallions. NAC and NAC supplements are also a precursor to the amino acid L-cysteine, and consequently, to glutathione, the body’s master antioxidant. Because NAC naturally replenishes glutathione inside the body, it can be especially important during the aging process since glutathione production slowly decreases as we age, putting us at increased risk of oxidative damage, and the diseases associated with oxidative stress. Seniors especially benefit from a boost of their glutathione levels.

Beyond stimulating the body’s production of antioxidants and helping to prevent free radical damage, NAC also supports and stimulates our inherent detoxification processes, and streamlines glucose metabolism, which increases insulin sensitivity, and helps improve conditions such as metabolic syndrome, central obesity, prediabetes, and type 2 diabetes. Because NAC has both antioxidant and anti-inflammatory properties, it is great to support healthy cell turnover and overall health.

Finally, it’s worth noting that NAC plays a critical role in regulating neurotransmitters insider the brain such as dopamine and glutamate, so supplementation is of considerable advantage to treating addiction, as well as support a balanced mood.

Benefits of NAC Supplements

  • Antioxidant & Anti-Inflammatory
  • Enhances Detoxification
  • Stimulates Glutathione Formation
  • Supports Optimal Lung Health

Who Benefits From NAC Supplements?

Practitioners often have recourse to NAC in their practice to help increase antioxidant levels, most notably, glutathione levels; to treat acetaminophen overdose, to support and protect bronchial tissues and overall lung health, especially to break up mucus in people with lung diseases, and bronchitis; to protect the liver; to prevent physical and neurologic damage caused by some prescription medications; as well as to address conditions such as hyperglycemia-induced oxidative damage, traumatic brain injury, as well as in psychiatric conditions as a standalone, or in combination with other supplements.

NAC Supplements

Potencies

NAC supplements are typically sold in potencies of 500 to 1,000 mg, and the recommended daily dose is usually in the 600-1800mg range, although higher doses may be recommended according to health status.

Formats

NAC can be found as a supplement in capsules, tablets, sprays, liquids, or powders. Practitioners can also administer NAC via IV.

Final Thoughts

NAC, like other single amino acid supplements, is best taken on an empty stomach.

While NAC is a supplement that is recommended to protect the liver and kidneys, very high doses may overtax these organs, so it’s important to always follow label instructions. Higher doses around 1,000 to 3,000 mg range may cause mild gastrointestinal symptoms.
