NeuroScience CysNAC

Inhibits glutamate by reducing intracellular concentrations and supports the production of glutathione.

Features of CysNAC:

CysNAC modulates the excitotoxic neurotransmitter glutamate and reduces oxidative stress. N-acetylcysteine has been shown to aid in the reduction of cravings, fixations, and urges. Cysteine plays an important role in the synthesis of glutathione, the body's toxin neutralizing powerhouse.  Because of cysteine's role in the production of glutathione, this product is recommended for individuals who need oxidative support.

NeuroScience CysNAC Recommended Use:

  • Take 1 capsule two to three times daily.
  • Use under the supervision of a licensed healthcare practitioner. If you are pregnant or nursing, consult your healthcare practitioner before use.
  • CysNAC is commonly used to address elevated glutamate levels and reduce oxidative stress. It has also been shown to aid in the reduction of cravings, fixations, and urges.
