From the Guidelines

To reduce gas, incorporating probiotics into your diet is a highly effective approach, as evidenced by the most recent study in 2024 1, which highlights the benefits of probiotics in maintaining gut health and reducing symptoms of gas and bloating.

Key Recommendations

  • Include probiotic-rich foods in your diet, such as kefir, yogurt, sauerkraut, tempeh, kimchi, and certain types of cheese, as these have been shown to improve digestion and reduce gas production 1.
  • Consider taking probiotic supplements, especially those containing Lactobacillus and Bifidobacterium species, which have been found to have a positive impact on gut microbiota and reduce symptoms of gas and bloating 1.
  • In addition to probiotics, making dietary changes such as avoiding common gas-causing foods, eating smaller meals, and staying physically active can also help reduce gas and improve overall digestive health.

Understanding Gas Production

Gas is a natural byproduct of digestion, but excessive gas can be caused by swallowed air, certain foods, or underlying digestive conditions.

Additional Considerations

While other studies, such as the 2022 British Society of Gastroenterology guidelines on the management of functional dyspepsia 1, provide valuable insights into managing digestive symptoms, the most recent and highest quality evidence supports the use of probiotics as a key strategy for reducing gas and improving gut health 1.

From the FDA Drug Label

Use for the relief of pressure and bloating commonly referred to as gas Purpose Antigas Directions adults: swallow with water 1 or 2 softgels as needed after meals and at bedtime do not exceed 2 softgels in 24 hours except under the advice and supervision of a physician To reduce gas, simethicone (PO) can be used. The recommended dosage is to swallow 1 or 2 softgels as needed after meals and at bedtime, with a maximum of 2 softgels in 24 hours unless advised otherwise by a physician 2, 2, 2.

From the Research

Reducing Gas

To reduce gas, several options can be considered:

  • Probiotics: Studies have shown that probiotics can help maintain gut health and reduce symptoms of gastrointestinal diseases, including gas 3, 4, 5.
  • Simethicone, activated charcoal, and magnesium oxide combination: Research has demonstrated the efficacy of this combination in reducing dyspeptic symptoms, including gas and bloating 6, 7.
  • Prebiotics: Although not directly mentioned in the provided studies, prebiotics are often used in conjunction with probiotics to improve gut health and may also help reduce gas 5.

Mechanisms of Action

The mechanisms by which these options reduce gas include:

  • Modulating the gut microbiota: Probiotics can help maintain a healthy balance of gut bacteria, which can reduce gas production 3, 4.
  • Reducing symptom intensity: The simethicone, activated charcoal, and magnesium oxide combination has been shown to reduce overall dyspeptic symptom intensity, including gas and bloating 6, 7.
  • Enhancing gut function: Probiotics and prebiotics can help improve gut function, which may reduce gas production and alleviate symptoms 5.
