This is the best probiotic on the market. It contains chitosan which breaks down candida yeast. If you have any type of allergies, acne, gut issues, autoimmune problems...you need this probiotic. I have been taking this for over a year, and it has kept me from having any IBS/diverticulitis issues(which I suffered from daily). I love these products so much that I became an ambassador with the company, so that I could help others to get healthy too!
