I have been taking Acidophilus with Bifidus and
FOS for a couple of years now and they keep my tummy issues to a minimum. They contain 6 billion non dairy active cells with FOS from above used as a base.
These are either the same or similar additives to these "health yogurts" with none of the extras you have to add if you have the yogurt.
The ones I buy are about $6 for 180caps, I take 3 a day, really cheap and make sure you keep them in the fridge for maximum active cell life.

Edit, I buy them in vitamin section of the grocery store
