Great in the short term, ask a dr before using it long term
NAC profoundly and rapidly improved my fatigue (ME/CFS). It worked fantastically for about a year for me. But around one year, I started getting really bad histamine intolerance symptoms, which got pushed over the edge after I switched to a more potent brand of NAC. The last few times I tried to take NAC, I had really severe neurological symptoms from histamine intolerance. Given how sensitive people with LC are to histamine intolerance and mast cell disease, I wouldn't recommend anyone take it long term. Maybe taking it in cycles would be safer.
