NAC (N-Acetyl Cysteine) is a high-strength amino-acid derivative providing 600 mg per capsule, commonly used in supplements as a precursor to glutathione, a naturally occurring compound in the body.

  • High-strength 600 mg per capsule
  • Precursor to glutathione
  • Clean, simple formulation
  • Suitable for regular supplementation

NAC is a modified form of the amino acid cysteine. In the body, cysteine is involved in the formation of several naturally occurring compounds, including glutathione. For this reason, NAC is widely included in nutritional supplements and is the subject of ongoing scientific research into its role in normal cellular processes.

In supplement form, NAC is often selected as a cysteine source because it offers stability and consistency, making it suitable for use in standardised formulations designed for regular intake.

This product is cleanly formulated with no unnecessary fillers or additives and provides NAC in a simple capsule format. It is intended for individuals looking to include NAC as part of a balanced diet and broader nutritional routine.

NAC has a strong sulphur-like odour, which is entirely normal.

The Science, Simply Put

NAC is short for N-acetyl cysteine; a modified form of cysteine, one of the building-block amino acids your body uses to make proteins. Cysteine itself is found in high-protein foods such as meat, eggs, dairy, legumes and whole grains.

In supplement form, it’s most often supplied as NAC because the acetyl group makes the molecule more stable and easier to standardise.

NAC is widely included in nutritional supplements as a precursor to glutathione, a naturally occurring sulphur-containing compound the body produces from cysteine, and it remains a subject of ongoing scientific research.

NAC has a natural sulphur-like smell that is completely normal and nothing to worry about.
