Review: Super effective! - These are super effective for regulating digestion. I've tried many kinds and always find the shelf-stable varieties pretty worthless, and the refrigerated ones to work better. This one I guess is somewhere in between, as the bottle says "Refrigerate AFTER opening". But they work just as well if not better than the good kinds I have bought straight from the cooler in Natural Grocers. And at a much cheaper price! Definitely worth a try.
Review: Excellent quality ,great value - This was the recommended brand from my hospital pharmacy. Has been taking this probiotic once a day to prevent possible C-Diff from being on six antibiotics for a severe lung infection in past 10 years. All these years has been working wonderfully in preventing diarrhea from the antibiotics . I do need to take additional capsule on the first sign of loose stool to regulate bowel movement back to normal. Also excellent pricing in comparing to much more expensive brand. Works well on travel diarrhea too.
