My baby is experiencing severe colic, I tried everything but nothing seems to work, I heard about biogaia, is it helpful in this condition?

Studies show yes. Probiotic supplements (and culture-fortified foods) are not regulated by the fda. Biogaia is just one form of adding lactobacillus to your babies intestinal cycle. A recent study does show there seems to be benefit though. Use caution and talk to your pediatriian about it. The correct dose has not been established.
