Beano is used to prevent and reduce gas, bloating, and abdominal discomfort caused by eating beans, lentils, soybeans, peas, broccoli, cabbage, and whole grain products. It is particularly helpful for individuals with dietary habits that include frequent consumption of gas-producing foods.
Beano contains the enzyme alpha-galactosidase, which breaks down complex carbohydrates (specifically oligosaccharides) in the digestive tract before they can ferment in the colon and produce gas. By aiding digestion at an earlier stage, it reduces the amount of gas generated downstream.
Beano is a dietary supplement, not a medication, and is not regulated as a drug. It should be taken at the start of a meal for best results. It is not intended to treat existing gas or digestive conditions caused by underlying disorders. Individuals with galactosemia or those allergic to Aspergillus niger (the source of the enzyme) should avoid this product. Consult a healthcare provider if digestive symptoms persist.
