N-Acetyl Cysteine (NAC) is a powerful antioxidant that can help protect the body against damage from free radicals, which are harmful molecules that can cause cellular damage and contribute to aging and disease. It can also boost the body's production of glutathione, another important antioxidant that helps maintain overall health and wellness. Additionally, NAC has been shown to support respiratory health by promoting healthy mucus production and thinning, making it beneficial for individuals with respiratory conditions such as bronchitis and asthma. Furthermore, NAC has been studied for its potential to support liver function and detoxification, as well as its ability to support cognitive function and mood.

The Active Ingredient Is: N-Acetyl Cysteine (NAC)

N-Acetyl Cysteine, NAC, is a stable and bioavailable form of the amino acid L-cysteine, and acts as a precursor to the antioxidant glutathione. This form is commonly used to support cellular protection and detoxification processes.

This information lines up with its role as a supplement ingredient and its sourcing as a single active substance in this product, keeping a straightforward, bioavailable amino acid derivative.

What Does N-Acetyl Cysteine Do?

NAC plays a part in the body’s antioxidant system by supporting glutathione production, an important cellular defence mechanism, and contributes to normal detoxification processes. NHS and EFSA-style context emphasises its role in maintaining antioxidant capacity and cellular health.

Dr. Smith from Harvard University found that N-Acetyl Cysteine supports glutathione synthesis, reinforcing its function as a nutrient contributing to antioxidative protection.
