Does Dannon Activia really work on your digestive tract?

Activia with bifidus regularis. probiotics

I’ve been tracking online comments on Activia. We’ve never had any problems with decent plain yogurts with normal active cultures. Probiotics are important if you need to be on antibiotics (which kill off the good as well as the bad bacteria), and as others have stated, good quality yogurts will have these in those active cultures. From what I've read, I guess people troubled by IBS are helped by this expensive, sugary product. But I stupidly bought some thinking my husband might benefit from it (he gets heartburn), and the benefits he got were a week of horrible intestinal cramps and constipation. Please be wary of these very uncomfortable consequences that may accompany eating Dannon Activia. Try a decent, unsweetened yogurt with active cultures first.
