“Which probiotics are best for gas?”

There is little to no clinical data that supports probiotics for this reason. Most flatulence and bloating is the result of carbohydrates that are not well digested, especially those in fruits and vegetables, bread, etc. A low carb diet such as the FODMAP diet works to reduce gas.

Any approved probiotic formulation that contains multiple bacterial strains is preferred. Make sure that you read the label carefully before starting.
