PharmaNAC at NYBC

PharmaNAC, an effervescent tablet formulation of NAC (N-acetylcysteine), has been available from the New York Buyers Club for several years. We are pleased to offer this formulation, both because it’s a high quality preparation with careful manufacturing controls and protective packaging, and because ongoing research on NAC has continued to point to its usefulness in many fields, from respiratory and immune system support to serving as an antidote to acetaminophen (common tradename: Tylenol) overdose.

Here are some product details from the manufacturer:

N-acetylcysteine or “NAC” for short, is a derivative of the amino acid L-cysteine, which is an essential precursor used by the body to produce glutathione. Glutathione is an important and powerful antioxidant produced by the body to help protect against free radical damage, and is a critical factor in supporting a healthy immune system.

• Certified European Good Manufacturing Process (GMP) grade NAC.
• Effective way to help boost glutathione levels.
• Effervescent, quick-dissolving tablets allow NAC to enter cells readily, ensuring rapid absorption.
• Quality controlled according to pharmaceutical guidelines.
• Compliant to the standards of European Pharmacopoeia and United States Pharmacopoeia.
• Individually wrapped tablets in a 4-layer (paper/plastic/foil plastic) air-tight material to prevent moisture and air from degrading the NAC (a major problem with most other over the counter NAC).

Regular supplementation with NAC (N-acetylcysteine) can help control chronic bronchitis

This study, published in 2000, looked back at two decades of research and found that regular supplementation with NAC was associated with better control of chronic bronchopulmonary disease (such as chronic bronchitis). Perhaps a good study to keep in mind, since we are approaching the season in North America when respiratory tract problems can become more acute.

Additional note on NAC: it’s an antidote to acetaminophen (Tylenol is the best-known brand name in the US) and can counter liver toxicity associated with  acetaminophen use. Widely used for this purpose in Europe, where NAC and acetaminophen are frequently combined.
