Take digestive enzyme supplements
Certain over-the-counter products may help with bloating, such as supplemental enzymes that can help break down indigestible carbohydrates.
Taking a lactose supplement before drinking milk helps with digestion of milk sugars and reduces the symptoms of bloating.
Another supplement to take is an enzyme called alpha-galactosidase, commonly known as Beano, which helps reduce gas and bloating caused by eating cruciferous vegetables.
