What is NAC?
NAC (N-Acetylcysteine) is a stable form of the amino acid cysteine, which is crucial for the body's own production of glutathione - one of the most powerful antioxidants we have. Cysteine and glutathione play central roles in the body's detoxification processes and protection against free radicals.
You get small amounts of cysteine through protein-rich foods such as meat, milk and eggs, but for optimal effect, many people choose to take NAC as a dietary supplement .
How does NAC work in the body?
When taken as a supplement, NAC is converted into glutathione in the body. Glutathione protects cells against oxidative stress, inflammation, and harmful substances . It also contributes to a strong immune system and helps the body detoxify from environmental toxins.
Research shows that NAC may support brain function and metabolism in people with neurological conditions such as multiple sclerosis and Parkinson's disease .
What are the health benefits of NAC?
Taking NAC regularly can provide several benefits:
• Increases the body's production of glutathione

Why take NAC as a dietary supplement?
The amount of NAC in the diet is often not sufficient to provide the same benefits as a supplement. Supplements provide a more precise and effective dosage and can be easily taken between meals for best absorption.

How much NAC should you take?
Studies typically recommend between 600–1800 mg per day . Higher doses should be split throughout the day to optimize absorption and minimize stomach upset.
Can I get NAC through food?
NAC is found naturally in animal foods such as meat, milk and eggs , but only in small amounts. To get the full benefit of NAC's properties, a supplement is recommended.
Powders provide flexibility to adjust the dosage, while capsules and tablets are convenient for daily use.
Can you overdose on NAC?
At normal dosages, NAC is safe. However, at extremely high intakes, stomach upset such as nausea or diarrhea may occur. Always stick to the recommended dosage.
