N-Acetyl-L-Cysteine (NAC) 90 Capsules

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.

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.

As well as those on restricted diets such as vegans or vegetarians, anyone looking to support their glutathione levels may find this stable and absorbable form of NAC supplementation beneficial. It may be particularly useful for older adults due to the fact that plasma cysteine and glutathione levels tend to decline with increasing age.

Maintaining adequate levels of glutathione within the body is very important for maintaining our health. The body produces its own glutathione and glutathione is found within most cells in the body where it protects them from oxidative stress and supports the detoxification of toxins and carcinogens. However levels may be depleted by poor diet, pollution, toxins, stress, ageing and infections.

Even partial glutathione depletion has been shown to impair immune function and increase our susceptibility to free radical damage. Glutathione is known as the 'master antioxidant' because of its ability to recycle other antioxidants, as well as protect cells from oxidative damage./p>

NAC may have an instantaneous beneficial effect on health (within a couple of hours), however many people who decide to take, or who are recommended to take NAC, may have more chronic health issues whereby benefits may not be seen for weeks and total resolution may take 2-3 months. For the best advice of dosage and frequency which is suitable for you, please 'ask a nutritionist'.
