Product Description

N-Acetyl L-Cysteine is an amino acid precursor to the important antioxidant glutathione which is found in all our cells.

NAC has a normal half life of 1 1/2 hours in the bloodstream, but Jarrow Formulas N-A-C Sustain has been designed to give a sustained release in the intestines over an 8 hour period. The two phase release technology used in the tablets means that 1/3 of the NAC is released quickly to immediately raise levels in the blood, while the other 2/3 have a sustained release to help maintain blood levels over an extended period.

Jarrow Formulas N-A-C Sustain Supports:

  • Liver health.
  • Glutathione levels.
  • Lung health.
