NAC is a precursor (or building block) to glutathione, the body’s most powerful antioxidant

NAC (N-acetyl-L-cysteine) is an amino acid precursor to glutathione. It supports liver health, respiratory function, and supports a healthy antioxidant status.* NAC also supports the breakdown of mucus in the lungs and helps replenish intracellular glutathione status, which can be depleted by excess stress, toxins, or illness, making it valuable for supporting immune status and overall metabolic balance.*

What This Product Is

NAC provides 900 mg of N-acetyl-L-cysteine per capsule, a unique form of the amino acid cysteine that acts as a key building block for glutathione, one of the body’s most powerful antioxidants. Glutathione is required to maintain liver health and the body’s natural detoxification process, helping to clear out everyday toxins and sustain overall balance.*

When the body is under stress, its glutathione levels can decline, so supplemental NAC helps replenish and maintain healthy glutathione status. NAC also supports muscle recovery, lung and brain health, a balanced inflammatory response, and overall reproductive health. Naturally found in onions and other Allium vegetables, NAC may be more readily absorbed and utilized by the body than supplemental glutathione itself.*

Mechanism of Action

Glutathione Precursor

NAC is a key building block for glutathione synthesis, delivering the rate-limiting amino acid cysteine in a form that the body can readily use. By supporting glutathione production, NAC helps maintain the body’s most powerful endogenous antioxidant system for protecting tissues and supporting detoxification.*

Liver Health and Detoxification*

Glutathione produced from NAC is essential for liver health and the body’s natural detoxification processes, helping convert toxins into safer compounds for elimination. NAC supports the liver’s ability to clear everyday toxins and maintain overall metabolic balance.*

Multi-System Antioxidant Support*

Through its role in glutathione production and direct antioxidant properties, NAC supports antioxidant status throughout the body, promoting healthy inflammatory responses and supporting the brain, lung, muscle, and reproductive tissues through oxidative stress.*

Athletic Applications

Individuals seeking to support glutathione production and antioxidant status*

Those wanting liver health and detoxification support*

Individuals looking for muscle function and recovery support*

Those seeking brain, lung, and reproductive health support*

Individuals under stress who may have declining glutathione levels*

Frequently Asked Questions

How does NAC compare to Liposomal Glutathione for antioxidant support?

NAC provides the building block (cysteine) that the body uses to produce glutathione endogenously, supporting the body’s own glutathione synthesis at 900 mg per capsule. Liposomal Glutathione provides pre-formed glutathione in liposomal format for direct absorption. NAC may be more readily absorbed and utilized than supplemental glutathione itself, while liposomal delivery enhances direct glutathione absorption. Both approaches effectively support glutathione status through different mechanisms.*

Why might NAC be preferred over direct glutathione supplementation?

NAC may be more readily absorbed and utilized by the body than supplemental glutathione itself, as glutathione can be broken down during digestion. By providing the rate-limiting amino acid for glutathione synthesis, NAC allows the body to produce glutathione where and when it is needed, supporting endogenous production rather than relying solely on exogenous supply.*

Who may benefit most from NAC?

Individuals seeking to support glutathione production and overall antioxidant status, those wanting liver health and detoxification support, people under physical or environmental stress whose glutathione levels may be declining, athletes seeking muscle recovery support, and anyone wanting broad-spectrum antioxidant protection for brain, lung, and reproductive health.*
