No. While some symptoms of gas can mimic heartburn - like discomfort after eating - antacids don’t relieve gas. They have a different active ingredient (example: calcium carbonate) that neutralizes the stomach acids coming into contact with your esophagus, rather than the buildup of gas in your digestive tract. The active ingredient in Gas-X is ‘simethicone’ and it helps break up gas bubbles in your stomach and intestines. Once this trapped gas is broken down, your body can then deal with the gas naturally.
