Hello. I am a loyal fan of GNC Cleansing Formula. I have taken it over 20 years. I have painful diverticulitis flareups when i am not taking it (due to financial issues - please bring back "Buy one, get one half off" special ??). Strongly recommend. You must be consistent about taking it, roughly same time, twice a day. I take one with morning 81mg aspirin, and second one at bedtime. Adding fruits and vegetables helps too.
