Activated Charcoal for Gas Reduction
Charcoal adsorbs gas in the lab, but human trials on flatulence are old, small and contradictory.
Overview
Verdict
Occasional use at most, and it interferes with everything else you take.
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- 500-1000 mg occasionally with a trigger meal

- Same meal, if at all
Protocol

- timing
- With or just after the offending meal, and at least 2 hours away from any medication or supplement
- duration
- Occasional use only - a few times a week at most
- titration
- Up to 1000 mg per occasion if 500 mg does nothing; do not use it daily
- measurement

Evidence
What the studies say
Activated charcoal, simethicone, and intestinal gas: a double-blind study
Jain NK, Patel VP, Pitchumoni CS
Activated charcoal reduced breath hydrogen and symptoms of bloating and cramping after a gas-forming meal, whereas simethicone did not.
Safety
Caveats
Adsorbs medications and nutrients, so separate by at least two hours. Causes black stools and can worsen constipation. Not for regular daily use.
