I have been battling stomach problems for the past 4 years. I started taking these Acidophilus Pearls a month or so ago, but not on a daily basis. However, yesterday I had another episode with my stomach hurting, as did my 11 year old daughter. I took one of the Pearls and felt better. A while later, the pain was back, I again took another Pearl and I felt better. This continued until bedtime, when I finally slept pain free. My daughter had what I think is the flu yesterday. Strange though, her stomach was hurting too, only far worse than mine. I finally gave her one of the Pearls and it seemed to help instantly. She was more reluctant to take them than I, but finally took them during the night and awoke this morning feeling better. I am not sure what is causing the stomach pain that we are encountering, as I am very careful with my diet, excluding gluten, maintaining healthy oils, plenty of greens and fruits. I am at a loss. But at least the Pearls seemed to help. I am going to stay on these Pearls. Maybe they will do some good?
