I had the same problem as Sharon from Santa Fe. I'm 42 now and for the last couple of years, I've had problems with everything I eat making me bloated and uncomfortable. I've tried everything I can think of, including elimination diets, with no luck. But activated charcoal really worked for me. I take 2 tabs in the morning and then 2 at night, each time about an hour after eating to give my body time to digest the meal's nutrients. I don't usually take it at lunch time because I only have soup or tea and that doesn't seem to upset me too much. I didn't have the diahorrea. My stools were solid and did change to a very dark brown/black and I felt very cleaned out. They passed more easily as well. I'll keep taking the tabs twice a day until I feel like I don't need them. My thanks to Sharon from Santa Fe for recommending this product. Girl, you rock!
