What it is

Simethicone is a mixture of dimethylsiloxane polymers and trimethylsiloxy-terminated dimethylsiloxane polymers. It is a clear, colorless liquid with a viscosity that can vary. It is produced through chemical synthesis.

Why it's used

Simethicone is used as an antifoaming agent. It works by breaking down gas bubbles in the digestive tract. It is often found in products aimed at relieving gas and bloating, such as antacids and digestive aids.

Health notes

In the United States, simethicone is generally recognized as safe (GRAS) by the FDA for its intended use as an antifoaming agent. It is not absorbed by the body and is considered non-toxic. International bodies like JECFA have evaluated simethicone and determined it is safe for consumption.

Allergen info

Simethicone is not derived from any of the 9 FDA major allergens. It does not contain gluten.
