Kivül Probiotics are scientifically studied micro-organisms that promote daily digestive health so you can feel good every day. Each pixie contains 15 billion cells from 8 different clinically, studied, human resident strains. Unlike other products that use generic versions of probiotic organisms, our strains can be identified down to the genetic level and can be matched to the studies that were performed on them. Kivül Probiotics are gluten free, soy free and dairy free, making it great for those who are lactose intolerant. We only use natural flavors and sweeteners! Take Kivül Probiotics every day and see the improvement they make.
