I did a little googling. It is a probiotic supplement that is supposed to help digest gluten. I read some of the reviews and they seem to help. If gluten bothers you your best bet is to avoid it. When eating out ask a lot of questions and make yourself high maintenance. For example if you are at iHop and order an omelet let them know that you are allergic and ask them to make sure there is no wheat in or near your eggs on the grill, my parents do this with shellfish. Also, eat at locally owned and operated places as they tend to be more apt to accommodate. That being said, I did read one comment that she keeps them on hand just in case there is some cross contamination.
As for lactose problems, My wife is severely lactose intolerant. She uses the Lactaid Instant pills when eating dairy and buys the Lactaid milk. It keeps her from getting nauseous and puking, though if she eats too much dairy she still has some discomfort. I have also heard that acidophilus can help for mild lactose intolerance.
