The evidence in words

The verdict

For glutathione / oxidative markers, N-Acetylcysteine (NAC) earns evidence grade B (moderate effect, high consistency) — there is real evidence here. Reliable biomarker effect

How it might work

By replenishing cysteine, NAC raises glutathione and buffers oxidative stress. It also modulates glutamate signaling, the basis for its psychiatric research, and breaks disulfide bonds in mucus, thinning it.

How to use it

600–1,800 mg/day for general antioxidant/mucolytic use; psychiatric trials often used 2,400 mg/day. Clinical (poisoning) use is a hospital protocol.

Safety & cautions

Generally safe; GI upset is the main complaint, and its sulfur smell is off-putting. Theoretical additive effects with nitroglycerin and, at high doses, mild antiplatelet action.

Bottom line

A genuinely useful compound with real mechanisms: glutathione support, mucus-thinning, and modest psychiatric-adjunct evidence. 600–1,800 mg/day; the dramatic uses (overdose antidote) belong to medicine.

How it is used

As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.

General
600–1,800 mg/day.
Psychiatric (trials)
~2,400 mg/day under care.
