N-Acetyl Cysteine (NAC) is a one-a-day formula that provides a full 600mg of NAC. NAC supplements can help top up your natural cysteine levels, ensuring optimal amounts. It is often helpful for those on a restricted diet, e.g. vegan or vegetarians, without adequate dietary L-cysteine containing foods, like chicken, turkey, yoghurt, cheese and eggs. NAC helps the body to maintain glutathione levels, which protect our cells from oxidative stress and damage against free radicals. It may benefit lung, brain and immune health. NAC has a strong sulphur-like odour, which is entirely normal.
