Quick Take

Only useful for specific poisonings under medical guidance; skip for daily 'detox' or gas relief.

Activated charcoal is a processed, highly porous carbon made from carbon-rich material; it has no meaningful food sources and is used as a medical adsorbent, not a nutrient. In the gut, it binds many drugs and toxins before they are absorbed, and by binding bile acids it may modestly lower LDL in older studies. The strongest evidence is for recent poisonings, with weaker and inconsistent data for gas relief and cholesterol. People directed by poison control or trying a short trial for bloating are most likely to benefit.

Proven Benefits

Treats certain acute poisonings

May reduce gas and bloating

May lower LDL cholesterol

Protocol

Amount

500 mg - 2 g

Frequency

As directed by clinician or poison control; for gas, 1-3 times daily

When

After meals for gas/bloating; for poisoning, take immediately as directed. Separate from all medications and supplements by at least 2 hours.

Onset Time

Acute, within 1 hour for poisonings; 1-2 weeks for gas or cholesterol

Who Should Consider

People told by poison control after a recent ingestion

Adults with occasional gas or bloating who want a short tria

People with elevated LDL using it only as a clinician-guided

How It Works

Its large porous surface adsorbs many compounds in the gastrointestinal tract, so less of some drugs and toxins reaches the bloodstream. Binding bile acids may also increase their loss in stool, which can reduce LDL in older studies.
