Easy to swallow capsules that come in two phases. The blister packs are clearly marked Phase 1 and Phase 2 and each phase contains different amounts of live flora. They are particularly useful for people on antibiotics but would be good for anyone needing to rebalance their gut flora. I always find capsules easier to swallow than tablets and I feel that these are best taken at supper time so that they have a longer chance to stay in your system and don't get flushed away with anything you drink during the day.
