How to implement: Dosing: General health : 600-1,200 mg daily (split doses) Liver support/detox : 1,200-1,800 mg daily Chronic illness/high oxidative stress : 1,800-2,400 mg daily (under medical supervision) Acute acetaminophen overdose : 150 mg/kg IV (medical emergency-prevents liver failure) Timing: Morning on empty stomach (better absorption) Or with meals (if causes GI upset) Split doses : 600 mg 2-3 daily Forms: Regular NAC : Most common, effective Sustained-release NAC : Longer-lasting blood levels Liposomal NAC : Enhanced cellular uptake Evidence: A meta-analysis of 18 studies found that NAC supplementation (1,200-1,800 mg daily) increased glutathione levels by 30-50% within 4 weeks
