NAC is a supplement form of L-cysteine, an amino acid needed to support the production of glutathione, the 'master' antioxidant.
 
Why choose NAC?
Designed to offer antioxidant support, NAC is a derivative of the amino acid L-cysteine. L-cysteine is one of the amino acids, along with L-glycine and L-glutamine, that is needed to make and replenish glutathione - the 'master' antioxidant. However L-cysteine is often considered to be the rate-limiting step in its production and so NAC can supply the body with bioavailable L-cysteine.

L-cysteine is found in most high-protein foods such as chicken, turkey, yoghurt, cheese and eggs. Not consuming enough L-cysteine rich foods may affect your ability to make glutathione. Therefore people who eat restricted diets may struggle to get enough L-cysteine from their diet.
 
What are the benefits of NAC?
NAC helps the body to maintain glutathione levels, which protect our cells from oxidative stress and damage against free radicals. This in turn supports immune and liver health, cognitive function and healthy ageing.
