Hi, Deathstalker. I used to take Bio-K in liquid form. It contains 50 billion live cultures each little bottle. Needs refrigeration. It comes in a little plastic container that looks like a milk bottle. It has the consistency of thin yogurt, and tastes good. It also comes in capsule form for people travelling and the capsules do not require refrigeration. I don't need it anymore, but when I was taking it I produced formed poops, as if I had a healthy colon. Keep in mind it will take a few days or week to work, and might make you a bit gassy at first because it is a milk product. Orange, blueberry, strawberry, plain flavours. You'll find it at health food stores (try whole foods?) in the fridge section.
