I find Benefiber no help at all, but regular psyllium - from the bulk food store- helps a lot.
23 years of UC which started after quitting smoking. In and out of flares which are usually triggered by antibiotics. Latest issue is endless diarrhea without blood or mucous.
Currently off all meds and probiotics. Using grapefruit seed extract, iron supplement, calcium, and psyllium seed powder with good effect.
