Activated Charcoal for Bloating Relief

Research suggests that activated charcoal may help reduce intestinal gas, bloating, and related digestive discomfort, with the most direct evidence coming from randomized controlled trials. A 1986 double-blind RCT found that activated charcoal significantly reduced breath hydrogen levels and self-reported bloating in participants from two distinct dietary backgrounds, and a 2011 RCT found meaningful symptom relief in functional dyspepsia patients using a combination product containing activated charcoal alongside other ingredients. Studies indicate that a European regulatory body has also evaluated and apparently recognized a basis for gas-related health claims, lending some institutional weight to the evidence base. However, limitations worth noting include the relatively small and dated nature of some individual studies, the fact that at least one RCT could not be fully evaluated due to unavailable abstracts, and that the 2011 clinical trial tested activated charcoal as part of a multi-ingredient formula rather than in isolation, making it difficult to attribute the observed benefits to activated charcoal alone.
