Details +

O2B NAC contains 600mg of N-acetyl-L-cysteine in each capsule. NAC is an acetylated form of the amino acid cysteine and acts as a precursor to glutathione, one of the body’s most important antioxidants. Glutathione helps protect cells against oxidative stress and supports the body’s natural detoxification and immune processes.

NAC also provides nutritional support for the lungs and respiratory system. Its mucolytic properties help support the normal thinning and clearance of mucus from the airways. The acetylated form of cysteine may also help protect it from stomach acid, supporting its absorption and availability within the body.

FAQs +

What is NAC?

NAC stands for N-acetyl-L-cysteine. It is an acetylated form of the amino acid cysteine and is used by the body as a building block for glutathione.

What is glutathione?

Glutathione is an antioxidant produced by the body. It helps protect cells against oxidative stress and supports natural immune and detoxification processes. NAC provides cysteine, an amino acid required for glutathione production.

How does NAC support respiratory health?

NAC has mucolytic properties, meaning it helps support the normal thinning and clearance of mucus from the respiratory tract. This can help maintain clear airways and normal lung function.

Does NAC support detoxification?

NAC supports the body’s natural detoxification pathways by helping provide the cysteine needed to produce glutathione. Glutathione is involved in antioxidant protection and the body’s normal cellular defence processes.

Why is the cysteine acetylated?

The acetylated form helps make cysteine more stable and may help protect it from stomach acid, supporting its absorption and availability within the body.

How many NAC capsules should I take each day?

Take 1–2 capsules together with food per day, or follow the directions provided by your healthcare professional.

Can I take NAC long term?

Prolonged use is not recommended without advice from your healthcare professional. Speak with them about the appropriate dose and duration for your individual needs.
