Features
- Supports respiratory health & relieves symptoms of chronic bronchitis
- Easily mixable powder for flexible, high-purity dosing
- A precursor to Glutathione, a potent intracellular antioxidant
Arcwell® NAC Powder delivers pure, pharmaceutical-grade N-Acetyl-L-Cysteine (NAC) in a convenient, unflavored powder form — ideal for those seeking clean, customizable support for immune function, detoxification, and respiratory health.
NAC is a stable form of the amino acid cysteine, which your body converts into glutathione, a powerful intracellular antioxidant. Glutathione plays a vital role in protecting cells from oxidative stress, environmental toxins, and free radical damage.
Research shows NAC helps:
- Relieve symptoms of chronic bronchitis
- Break down and clear excess mucus in the lungs (especially in cases of cystic fibrosis or COPD)
- Reduce the frequency and severity of flu-like symptoms
- Support immune response and DNA integrity
As a powder, Arcwell® NAC offers maximum flexibility for those who prefer to tailor their dosage — ideal for wellness practitioners, high-performance users, or those on therapeutic regimens.

Frequently Asked Questions
Do you really manufacture in Canada?
Yes, indeed. All Arcwell products are meticulously formulated and packaged in Victoria, BC, Canada, within a GMP-compliant facility, VitaHelix Nutraceuticals Ltd. This facility holds a valid site license approved by Health Canada, ensuring stringent quality standards. Our manufacturing process takes place in an ISO 8 pharmaceutical-grade clean room equipped with a state-of-the-art HEPA (High-Efficiency Particulate Air) filter system. This meticulous setup guarantees precise particle control and maintains the utmost purity of the air within the production area.
At Arcwell, we prioritize quality assurance, and one way we achieve this is by handling the production of our dietary supplements in-house. This approach sets us apart from most other companies that opt to outsource production, allowing us to maintain direct oversight and control over every aspect of our product's quality.
What’s the best time to take Arcwell products if I purchase more than one product?
Here is our suggestion. If you get all 4 Arcwell products at once, you may take NAC together with Glutathione during the breakfast with a meal, and NMN together with trans-Resveratrol at lunchtime with or without meals.
If you just take NMN, we suggest taking it in the morning with or without a meal or 30 min prior to exercise.
If you take NAC and/or GSH, we suggest taking in the daytime with a meal. And a special note: since the compound contains sulfur, don’t take it together with any minerals such (Iron, Zinc, Magnesium, etc.). Please take it at least 4 hr apart from the minerals or multivitamins.
If you just take trans-Resveratrol, anytime could be fine.
Is Arcwell NAC Vegan, Kosher and Halal friendly?
Yes, Arcwell NAC is vegan-friendly. We do not use any animal products or by-products in our ingredients. Furthermore, our ingredient NAC is sourced from the United States with Kosher and Halal certification.
Where are your materials sourced from?
Arcwell was founded by three scientists in Victoria BC and our mission is to provide high-purity dietary supplements with scientifically proven results to improve your health. We want you to have the correct information to make proactive decisions about your health vs. being reactive and treating illness.
Our ingredients are sourced from various locations around the world such as Switzerland for our Resveratrol, the US for our NAC, and China for our Glutathione and NMN. We are meticulous in selecting our suppliers and work with trusted partners who share our dedication to quality. Our aim is to provide pharmaceutical-grade supplements that meet the highest standards. To ensure the purity and quality of our ingredients, we have rigorous testing procedures in place. Each ingredient undergoes thorough testing both in-house and by reputable third-party laboratories. Our standard is to achieve a purity level greater than 99%, exceeding industry norms.
Additionally, we believe the best way to oversee quality is to produce our dietary supplements ourselves. Our ISO 8 clean room is a GMP-compliant facility approved by Health Canada.
