Activated charcoal (oral)

Tier 3 — weak evidence · Detox claims · Gas

Only has evidence for emergency poisoning treatment in hospitals (within 1 hour of ingestion). No evidence supports "detox" benefits or daily wellness use. It binds medications and nutrients indiscriminately, reducing their effectiveness. Taking it regularly can actually prevent your body from absorbing important vitamins and medications you need.

Dose: Not recommended as a supplement; medical use only for acute poisoning
