Theralac is the very first probiotic I purchased for my son after his diagnosis. He used it exclusively for the first year and a half or so (after that, I began trying other brands). He took one every day, though, so it really ended up being one of the more expensive choices out there for us. Well worth every penny, however! I think it's a GREAT probiotic and was VERY satisfied with it. If you get on their email list they periodically send "coupons" to you, too. If I remember correctly, I also think you get a price break if you order more than one bottle at a time. Ironic you brought it up because I was just getting ready to order some again...
