What is N-Acetyl Cysteine?

N-Acetyl Cysteine (NAC) is a supplemental form of the amino acid cysteine and a precursor to glutathione, the body's primary intracellular antioxidant. Research has explored its potential role in reducing oxidative stress in brain tissue and supporting neurotransmitter balance, particularly glutamate regulation.

What dosage of NAC has been used in brain health studies?

Clinical studies for neurological and cognitive outcomes have typically used 600 mg to 2,400 mg of NAC daily, often divided into two doses. A common starting dose is 600 mg twice daily. Consult your healthcare provider for personalized recommendations.

What are the potential side effects of NAC?

NAC may cause nausea, vomiting, diarrhea, and stomach discomfort. It has a sulfurous taste and smell. NAC may interact with nitroglycerin and blood-thinning medications. People with asthma should use caution as inhaled NAC may cause bronchospasm. Consult your healthcare provider.

About

NAC is a precursor to glutathione, the brain's primary endogenous antioxidant. It modulates glutamate neurotransmission and has demonstrated neuroprotective effects in brain injury models, with MRI studies showing improvements in brain connectivity.

How It Works

Precursor to glutathione, the brain's primary endogenous antioxidant; modulates glutamate neurotransmission; reduces neuroinflammation and oxidative stress.
