I've been taking NAC (MaxGxl) for several years, to help with sarcoid, glutathione enhancement, etc. Recently learned that NAC can cause wheezing, bronchial breathing problems, etc. I recently have been experiencing these issues, but associated them with my sarcoidosis flaring up, or getting worse due to weight, age, etc. Now I think maybe NAC is causing issues, but not sure?! Is NAC side effects common?
