N-Acetyl Cysteine in depth
What it is
N-acetylcysteine (NAC) is the acetylated form of the amino acid L-cysteine. Cysteine is one of the building blocks the body uses to make glutathione, a major antioxidant molecule. In hospitals NAC is also given by injection or by mouth under medical supervision, for example as the standard treatment for paracetamol overdose and as a mucus-thinning medicine. That clinical use is separate from its use as a dietary supplement.
Forms you may see on a label
NAC is a white crystalline powder with a strong sulphur smell and taste, which is why it is often sold in capsules, tablets or flavoured effervescent powders. The label shows the amount in milligrams.
Where it occurs naturally
NAC itself is not found in meaningful amounts in food. Cysteine occurs in protein-rich foods such as poultry, eggs, dairy products, pulses and seeds.
Safety notes and who should check first
Reported side effects include nausea, vomiting, diarrhoea, stomach upset and, in some people, a skin rash. NAC can interact with nitroglycerin, increasing its effect on blood pressure and headache, and it may affect blood clotting.
Check with a doctor before use if you are pregnant or breastfeeding, have asthma, or take nitroglycerin or blood-thinning medicines.
