Actually, florastor kids does not have milk in it. It does have small amounts of lactose in it, but their research showed that even in people with lactose intolerance, most tolerated the product. Florastor is not the same as normal probiotics. It is a yeast that actually helps to kill the spores in the colon created by c-diff, and that’s why it works. You can just go with regular probiotics and flaggyl, and then if it comes back, consider the florastor. As I said, it really saved me.
