Best Probiotic I have tried. They are pricey, but worth it. I love that they are so pure, no fillers and no magnesium stearate(I am allergic and it is harder and harder, to find supplements without it!!). Because my gut is a mess I have to take 3 a day rather than the recommended one per day. But it has worked amazingly. Even after a short course of antibiotics, put me back to square one, it wasn't more than a week and I was back to being myself. I do hope to reach a point where I can tapper off to just one a day. In the mean time two thumbs up!!
