When free radicals attack, fight back with NAC! As a powerful antioxidant amino acid, Swanson NAC (N-acetyl cysteine) is an important weapon in the war against free radicals and offers 600 mg of NAC per capsule. NAC helps replenish glutathione, a critical component of the body’s defense system. It supports liver health and much more.

NAC (N-acetyl cysteine) promotes healthy respiratory function through its antioxidant properties. NAC also stimulates production of glutathione, the body’s master antioxidant. Healthy glutathione levels help the body fight oxidative stress from free radicals, support immune system function and may even promote healthy aging. NAC also supports healthy levels of glutamate, a neurotransmitter that is central to learning, behavior and memory. Additionally, NAC and glutathione support the body’s detoxification pathways for healthy liver function.

When it comes to boosting your liver health and gaining antioxidant support, nothing quite compares to taking an N-Acetyl Cysteine or N-acetylcysteine supplement, which is sometimes referred to as a NAC supplement. There are multiple benefits of NAC, including boosting the body’s ability to neutralize free radicals by promoting glutathione production, which is essential for optimal immune, neuronal and cardiovascular health.

What is N-Acetyl Cysteine?

NAC is an amino acid that is involved in replenishing levels of the intracellular antioxidant glutathione (GSH). Glutathione is an important antioxidant that supports the body’s defense against free radical damage and plays a role in detoxification pathways.

Why Choose an N-Acetyl Cysteine Supplement?

Liver and detoxification support are two main reasons people consider a N-acetylcysteine supplement. As a form of the amino acid cysteine, NAC helps support glutathione production in the body, which plays a role in detoxification, cellular antioxidant activity and the body’s defenses against damage-causing free radicals. Swanson N-Acetyl Cysteine provides powerful antioxidant amino acid support.*
