When taken before eating, Beano works to break down and digest complex carbohydrates, such as those found in certain vegetables, legumes, whole grains, and more. These foods commonly cause gas.
This article explains the benefits of taking Beano. It also discusses possible side effects and precautions to take if you have certain health conditions.
Health Benefits
Beano works to digest sugars that are in many complex carbohydrates, including raffinose, stachyose, and verbascose. Beano also works on sugars known as oligosaccharides and polysaccharides.
The human digestive system has a hard time breaking down many of these carbohydrates. If they reach the colon (large intestine), bacteria ferment them and produce gas.
When taken before eating foods that contain these carbohydrates and sugars, Beano turns them into simple sugars that are easier to digest before they reach the colon. This helps prevent or reduce gas.
However, Beano is not effective in preventing gas caused by difficulties in digesting lactose or fiber.

Possible Side Effects
There are no known common side effects of Beano. However, it is always possible for any drug or supplement to cause side effects in some people.
If you have an allergy to alpha-galactosidase, you should not take Beano, as this is the primary ingredient in the supplement. Alpha-galactosidase is extracted from a food-grade mold, so it is also possible that some people could have an allergic reaction to that mold.
Symptoms of an allergic reaction may include:
RashesHivesSwollen and blistered skinFeverWheezingDifficulty breathingSwelling of the mouth, face, lips, tongue, and/or throat
There is no evidence that Beano is unsafe for pregnant women or women who are breastfeeding. Beano has not been tested in children, so you should consult your child’s healthcare provider before giving them Beano. There have been no recalls or warnings issued relating to Beano.
Precautions With Diabetes
If you have diabetes or a genetic condition called galactosemia, you should not take Beano without consulting your healthcare provider first. Both galactosemia and diabetes affect how the body processes sugar. The main ingredient in Beano breaks down indigestible sugars into digestible sugars, which can impact blood glucose levels.
Prescription medications for diabetes help regulate blood glucose levels. Taking Beano with diabetes medication may cause dangerous complications.
Dosage and Preparation
Beano may be taken as a chewable tablet and a meltaway tablet. Beano should be taken immediately before eating foods that cause gas, but this supplement is also effective if taken up to 30 minutes after eating.
The following doses are recommended:
Chewable tablets: 2 to 3 per mealMeltaway tablet: 1 per meal
Meltaway tablets are placed on the tongue and dissolve without chewing or swallowing. Beano tablets can also be crumbled onto your food and eaten with your meal if you prefer. Beano should not be used in cooking. Heat will break down the enzymes, and it won’t work.
Beano can be taken with every meal. You can double the dose if you are eating more than a standard serving size of problematic foods.
Store Beano at room temperature away from heat and moisture. Don’t use it if its expiration date has passed; ask your pharmacist for the best way to dispose of it.
What to Look For
It is typically recommended to take Beano rather than the primary enzyme alpha-galactosidase, which may be sold as a separate supplement. If you have questions or concerns regarding which is best for you to use, consult your healthcare provider or a pharmacist.
This supplement does not contain animal products and is considered vegan. Beano is largely considered a sodium-free product, containing only a very small amount of sodium at 5 milligrams (mg) per tablet.
There are no differences in the effectiveness of liquid drops, oral capsules, or chewable tablets, as long as each is taken as recommended.
Summary
Beano is an over-the-counter product that helps prevent gas, farting, and bloating when you take it before meals that include vegetables, grains, and legumes that can cause these symptoms. It is considered safe for people who do not have diabetes or an allergy to the main ingredient, an enzyme called alpha-galactosidase.
A Word From Verywell
If you often have gas or bloating after eating foods like broccoli, cauliflower, beans, and whole grains, Beano may help prevent these uncomfortable symptoms. Ask your doctor if you have diabetes or any other concerns before taking this supplement.
Instead, try simethicone to relieve gas. It is sold as the brand name Gas-X.
