N-A-C Sustain — 600 mg
60 tablets; 60 servings
TabletsVegan
The manufacturer lists 600 mg N-acetyl-L-cysteine per tablet. The bilayer tablet combines quick-release and sustained-release portions; this is NAC, a glutathione precursor, rather than glutathione itself.
Oral NAC can cause nausea, abdominal pain or diarrhea. Nitroglycerin combinations can cause low blood pressure and severe headaches; review medicines with a clinician. Tell the clinician about NAC before liver-function testing. Supplement use is not a substitute for medically administered acetylcysteine.
Product strengths describe the label, not personal dosing advice. If you use medicines, have a medical condition, are pregnant or are choosing for a child, ask a qualified clinician about suitability. Prices, availability, import charges and delivery are confirmed by the retailer. Photos may show market-specific packaging. Text covers identify editorial profiles and do not depict packaging.
