N-acetyl-L-cysteine is a glucogenic, sulphurous amino acid that is synthesized in the liver.
It possesses anti-oxidant properties and may improve the defence response of the immune system. People with depressed immune function usually exhibit significantly depressed cysteine levels.
N-acetyl-L-cysteine minimizes the toxic side-effects of chemotherapy. Discuss with medical practitioner if undergoing cancer treatment.
