NAC (N-acetyl cysteine)
NAC, N-acetyl cysteine, is the acetylated form of the amino acid cysteine. It is sold mostly in capsules and tablets, usually at 500–600 mg each, and some products add selenium or molybdenum.
NAC has a typical sulphur smell, which is normal for the substance and not a sign of a spoiled product. Compare the milligrams per daily dose and the price per dose.
The EU has authorised no health claim for NAC, so the product pages describe the form and the dose, not an effect.
