NAC is a metabolite of Cysteine , which is found in foods rich in protein. N-Acetyl Cysteine is produced within the human body, so not naturally found in foods. In the sulfation cycle, Cysteine acts as a sulphur donor, detoxifying and as a methyl donor in the conversion of homocysteine to methionine. Cysteine also helps synthesize glutathione, which is one of the body's most important natural antioxidants and detoxifiers, converting chemicals into much less harmful compounds.
NAC is therefore very effective in aiding liver protection, especially for those whose livers are under high stress.
Dosage
A typical dose of N Acetyl Cysteine is between 250mg and 2000mg per day.
