Activated Charcoal

In brief

Activated charcoal is a fine powder derived from carbonized plant materials, then activated to create a highly porous, adsorptive surface.
👉 It binds to certain gases, toxins, and compounds in the digestive tract, helping to reduce bloating and mild diarrhea.
⚠️ It should be used occasionally, not as a long-term treatment.

🟢 What it does (main evidence)

• Bloating / gas: moderate effect confirmed in some studies, mainly short term.
• Acute poisonings (medical use): proven effectiveness in cases of toxic ingestion (emergency settings).
• Occasional relief: helpful after heavy meals or mild intestinal discomfort.

🟡 What’s unclear

• Few robust studies for chronic use.
• Effectiveness varies depending on the cause (dietary, fermentation, stress).
• No strong evidence of a systemic “detoxifying” effect (mostly marketing claims).

🔴 What it doesn’t do

• Does not detoxify the liver or blood.
• Does not promote weight loss.
• Provides no nutrients or direct anti-inflammatory action.

Dosage & usage (non-prescriptive)

• 500–1000 mg, 1–2×/day as needed, always with plenty of water.
• Occasional use (1–2 days).
• Separate intake by 3–4 h from any important medication or supplement.
• Not for children or pregnant women without medical advice.

Safety

• Well tolerated when used occasionally.
• May cause constipation or dark stools (harmless effect).
• Long-term use not recommended (may interfere with nutrient and drug absorption).

Risks & interactions

• May cause constipation; may adsorb medications if taken at the same time.
• Separate by **3–4 h** from any important medication or supplement.

Quality tips

• Choose activated vegetable charcoal made from coconut shells or natural wood.
• Avoid “detox” products with sugars or additives.
• Look for the label “pharmaceutical-grade activated charcoal” (guaranteed purity).
