  • Top Notch Probiotic

    Posted by Bernice Morris on Aug 12th, 2015

    Taking Polyflora three years now, after battling a bad stomach for many years.

    It did the trick! If my stomach acts up, it only lasts at most, for a day..And that happens rarely.

    I have tried half a dozen differect probiotics, and before I tried Dr. D'Adamo's Polyflora, I could not tolerate any of them. This probiotic helps my bowel regularity and bloating. I will continue to take it as long as he keeps making it!
