The evidence in words
How much to take
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.
Timing & separation
There are no strict timing conflicts on record for N-Acetylcysteine (NAC); consistency matters more than the exact hour for most goals.
Why the dose is what it is
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.
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.
