Jain NK, Patel VP, Pitchumoni CS
Published in Annals of Internal Medicine
Methodology
Double-blind crossover study measuring breath hydrogen and symptoms after a gas-producing meal with activated charcoal, simethicone or placebo.
Key Findings
Activated charcoal significantly reduced breath hydrogen levels and symptoms of bloating and abdominal cramping after a gas-forming meal, whereas simethicone did not.
Conclusions
Activated charcoal can reduce meal-related intestinal gas symptoms in the short term, though the trial is small and dated.
Limitations
Very small crossover sample, single meal challenge, surrogate breath-hydrogen endpoint, 1986 methodology, and no data on repeated or long-term use.
Supplements Studied
Activated charcoal reduced breath hydrogen and symptoms of bloating and cramping after a gas-forming meal, whereas simethicone did not.
Outcomes Measured
Activated charcoal significantly reduced breath hydrogen levels and symptoms of bloating and abdominal cramping after a gas-forming meal, whereas simethicone did not.
