Beano
Beano is an over-the-counter preparation of alpha-galactosidase, an enzyme that metabolizes certain complex carbohydrates. It helps the body digest the sugar in beans and many vegetables.
"We do not have the ability to digest beans well, which in some people causes a lot of gas," Dr. Saltzman says.
Beano is not useful for gas caused by foods other than beans, he adds. The product comes in liquid form. Three to 10 drops are added to a serving of food just before eating to break down the gas-producing sugars.
