NAC is a highly stable and bioavailable form of the amino acid cysteine. L-cysteine is needed to support the production of glutathione; the body's 'master' antioxidant. 

Key benefits of NAC:

  • NAC is renowned for its ability to replenish levels of glutathione; the body’s 'master' antioxidant. Antioxidants help to maintain healthy cells by protecting them against oxidative stress and damage against free radicals
  • L-cysteine is found in most foods high in protein. However, not consuming sufficient protein, potentially as a result of restrictive diets, may lead to an inability to make enough glutathione
  • NAC also plays an important role in the body’s detoxification process, supporting the respiratory and circulatory systems, and regulating levels of glutamate; the most important neurotransmitter within the brain
  • L-cysteine is important for keratin synthesis for healthy skin, hair and nails
  • Levels of cysteine may become depleted during times of stress, low immunity, or poor protein intake. The requirement for cysteine can therefore increase beyond the body’s ability to synthesise it
  • The ability to synthesise cysteine and glutathione also decreases with age
  • L-cysteine is one of the only amino acids to contain sulphur. NAC has a strong sulphur-like odour, which is completely normal
  • Each capsule comprises 500mg of N-Acetyl-L-Cysteine in an easy-to-swallow, convenient one-a-day capsule
