The VSL#3 capsules contain 112.5 billion live bacteria each. The bottle contains 60 capsules.
VSL #3 is a potent probiotic medical food, and it has great reviews on Amazon. In order for it to be effective, it need proper storage, at the correct temperatures. This seller stores it in a refrigerator, and ships it in a cold pack. This is the best way to ensure bacteria viability. I recommend you to choose the expedited shipping, as it is safer, even if the seller uses a cold pack.
