What does it do?

Dimethicone is a silicone-based ingredient used to eliminate gas from the gastrointestinal tract. It is mainly used to relieve indigestion or abdominal bloating. It is also sometimes used as an adjunct in the treatment of constipation.

Dimethicone helps to reduce gas bubbles in the gastrointestinal tract, making it easier to expel. As a result, abdominal bloating and discomfort are reduced. It effectively manages gas that occurs during the digestive process.

Approved uses differ by product. Check each product's information for its actual use.

Good to know

Unlike other digestive aids, dimethicone is specialized for gas removal without direct digestive enzyme action. Moreover, it is minimally absorbed by the body, making it safe to use. This characteristic distinguishes it from other laxatives or digestive stimulants.

  • QWhat is the difference between digestive enzymes and dimethicone?

    Dimethicone does not directly act on food digestion like digestive enzymes; rather, it is specialized for removing gas from the gastrointestinal tract. Therefore, it is distinguished in the explanatory materials from other digestive aids. When taking more than one digestive aid, please verify whether the ingredients overlap.
