HelloPharmacist Scorecard of Activated Charcoal 520 mg by Windmill Natural Vitamins

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: activated charcoal powder at 520 mg per capsule. Activated charcoal is a highly porous form of carbon that works by binding substances in your digestive tract.

The capsules also contain gelatin and magnesium stearate as inactive ingredients.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: supports digestion and promotes cleansing detox.
  • We looked for evidence on: Dyspepsia, Flatulence, Poisoning, bloating, gas, upset stomach.
  • The strongest evidence on file: Activated Charcoal is rated "Possibly Effective" for Poisoning (Natural Medicines).
  • Also on file: Activated Charcoal is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia, Flatulence.

The evidence for activated charcoal is mixed. It's rated possibly effective for poisoning — which is its main use in emergency medicine.

For other uses listed here — high blood phosphate levels (hyperphosphatemia), wound healing, indigestion (dyspepsia), hangover, and high cholesterol — the evidence isn't strong enough to rate, meaning we don't have reliable data showing it works for those purposes.

The evidence, ingredient by ingredient Activated Charcoal

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Activated charcoal is generally well tolerated for short-term use, but constipation is the most common side effect and may be bothersome. You may also notice black stools, bloating, abdominal pain, or gas.

Rarely, it can cause gastrointestinal obstruction. Because it binds other substances so readily, it can also reduce how much your body absorbs from foods and supplements.

Safety data for routine use in pregnancy is limited. The product is rated possibly safe, but there isn't enough information to know for sure — talk with your doctor or pharmacist before using it during pregnancy.

Little safety data exists for breastfeeding either, so check with your healthcare provider.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Activated Charcoal.
  • The most serious interaction on file is rated Major.
  • For scale: 2,028 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check your medications with the tool on this page. The biggest concern is oral medications — activated charcoal can reduce how much your body absorbs.

Also watch for oral contraceptives (birth control pills), which may become less effective, and avoid taking this product close in time to alcohol, which can reduce how well the charcoal works.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Activated charcoal is mainly used for poisoning in acute situations. If you take it for other reasons, know that it can interfere with many medications and reduce their effectiveness.

Talk with your pharmacist before starting it, especially if you take any prescription drugs, birth control, or routine medications — timing and spacing matter.

Activated Charcoal, Powder3 drug types · 2,027 drugs

Oral Drugs

Activated charcoal reduces systemic exposure to many drugs, including those that undergo enterohepatic recirculation, regardless of the route of administration.
Activated charcoal adsorbs various drugs and may reduce their absorption and/or half-life. Examples of affected drugs include acetaminophen, aminophylline, amiodarone, atenolol, carbamazepine, dapsone, digoxin, disopyramide, fluoxetine, indomethacin, moxifloxacin, nadolol, phenytoin, phenobarbital, piroxicam, quinine, sotalol, theophylline, tricyclic antidepressants, valproate, and verapamil. Avoid co-administration, except after drug overdose.

Likelihood Probable Evidence B
Alcohol (Ethanol)

The binding action of activated charcoal may be reduced by alcohol.
Alcohol may lower the adsorptive capacity of activated charcoal.

Likelihood Probable Evidence D
Contraceptive Drugs

Activated charcoal may reduce the clinical effects of oral contraceptives.
Activated charcoal, taken in a dose of 5 grams four times daily for 3 days, may bind to, and reduce the absorption of, oral contraceptives, thereby limiting their effectiveness and increasing the risk of contraceptive failure. However, some clinical research shows that the risk for this interaction is minimal when activated charcoal is taken either 3 hours after or at least 12 hours before oral contraceptives.

Activated Charcoal 520 mg by Windmill Natural Vitamins: Common Questions

Does Activated Charcoal 520 mg by Windmill Natural Vitamins interact with any medications?
Yes. Based on its ingredients, Activated Charcoal 520 mg has a known interaction with 2,027 medications, including 2022 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Activated Charcoal 520 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will activated charcoal interfere with my medications?
Very likely. Activated charcoal binds to many drugs in your digestive tract and can reduce how much your body absorbs, potentially making them less effective. Check every medication you take — prescription, over-the-counter, and supplements — using the search tool on this page before you start.
Can I take this with my birth control?
It's risky. Activated charcoal can bind to oral contraceptives and lower their effectiveness, raising the chance of contraceptive failure. If you use birth control pills, talk with your pharmacist about timing or whether this product is right for you.
What are the most common side effects?
Constipation is by far the most frequent complaint, though it's usually temporary. Black stools, bloating, belly pain, and gas are also common. Rarely, it can cause a blockage in your digestive tract.
Is activated charcoal safe to use long-term?
It's not well studied for routine, ongoing use. It's generally low-risk for short-term use, but long-term or frequent use isn't established as safe. Talk with your pharmacist about how often and for how long you plan to take it.
Does this work for hangover or indigestion?
The evidence isn't strong enough to say. For hangover and indigestion (dyspepsia), we don't have reliable data showing activated charcoal actually helps. It is rated possibly effective for poisoning, which is its main established use.
Is it safe in pregnancy?
It's rated possibly safe, but there isn't enough data to be sure. If you're pregnant or planning to be, talk with your doctor or pharmacist before using it — they can give you personalized advice based on your situation.
