What NAC is. N-acetyl cysteine is a stable, supplement-friendly form of the amino acid cysteine. Cysteine is the amino acid that limits how much glutathione a cell can make, so NAC is taken as a way of supplying that raw material. It has a sulphur smell, which is normal for the compound.
How it differs from glutathione. NAC is the precursor; glutathione is the finished molecule. The case for NAC over swallowed glutathione is that cysteine is reliably absorbed while the evidence for oral glutathione is thinner. The Nutri Tailor guide linked below sets out what the NAC trials show and where the claims outrun them; Nutri Tailor makes no claim beyond that.
Who chooses it. People who want a glutathione precursor at a known dose, usually on a practitioner's suggestion. People who already take glutathione and want the raw material alongside it. Anyone who wants a single-ingredient capsule.
Capsules or powder. NAC powder tastes strongly of sulphur, which is why most people prefer a capsule. Nutri Tailor stocks the capsule at 375 mg; two capsules give 750 mg.
How to take it. One capsule daily with food, as the label directs. If you take prescribed tablets, have asthma, are pregnant or breastfeeding, or have a diagnosed condition, talk to your GP or pharmacist first. The Nutri Tailor guide What is NAC good for, and what does the evidence show? covers the evidence.
