NAC plays a significant role in detoxification by supporting the production of glutathione, a vital component of the body’s detoxification processes. Glutathione is involved in neutralizing free radicals and eliminating toxins from the body.

• Glutathione Precursor: NAC serves as a precursor to glutathione, meaning the body uses NAC to make more glutathione.
• Liver Support: By increasing glutathione levels, NAC supports the liver in its detoxification functions, helping to remove harmful substances from the body.
• Heavy Metal Detoxification: NAC can bind to heavy metals, such as mercury and lead, facilitating their removal from the body.
• Environmental Toxin Protection: NAC can help protect against the harmful effects of environmental toxins by reducing oxidative stress and supporting detoxification pathways.
