What is Activated Charcoal?

Activated charcoal refers to charcoal that has undergone an activation process to increase its surface area and make it highly adsorbent. The activation process involves exposing charcoal to high temperatures and steam, creating pores that allow it to trap and bind to various substances.

Activated charcoal is used for a range of purposes, including medical treatments, water filtration, and beauty products.

What Does Activated Charcoal Do?

Activated charcoal has several applications:

  • Gas and Bloating: Some people use activated charcoal supplements to alleviate gas and bloating by trapping excess gas in the digestive system.
  • Water Filtration: Activated charcoal is commonly used in water filters to remove impurities and contaminants.
  • Poisoning and Overdose: In cases of poisoning or drug overdose, activated charcoal can be administered in a medical setting to help absorb the harmful substances.
  • Teeth Whitening & Skincare: Activated charcoal, a natural wonder, brightens smiles by gently lifting stains from teeth and refreshes the complexion by detoxifying and clarifying the skin.

How Does Activated Charcoal Work?

Activated charcoal works through a process called adsorption, not to be confused with absorption. Adsorption refers to the binding of molecules to the surface of a solid or liquid. In the case of activated charcoal, its porous structure provides a large surface area for molecules to adhere to. This property makes it effective in trapping toxins, chemicals, and impurities.

When ingested, activated charcoal can trap harmful substances in the gastrointestinal tract before they are absorbed into the bloodstream. It essentially acts as a "sponge" for toxins, preventing their absorption and allowing the body to eliminate them naturally.

Is Activated Charcoal Safe?

Activated charcoal is generally considered safe when used appropriately. However, there are some important considerations:

  • Dosage: Proper dosing is crucial. Consuming too much activated charcoal can lead to side effects like constipation or gastrointestinal discomfort.
  • Timing: Activated charcoal should not be taken with medications or supplements, as it can interfere with their absorption. It's best to wait at least two hours after taking other substances before using activated charcoal.
  • Consultation: If you have underlying health conditions or are taking medications, consult a healthcare professional before using activated charcoal.
  • Quality: Ensure you're using activated charcoal meant for consumption or medical purposes. Do not use charcoal from sources like grills or campfires, as they may contain harmful chemicals.

When to Take Activated Charcoal?

Knowing when to take activated charcoal is crucial for harnessing its benefits effectively. Typically, it's recommended to take activated charcoal on an empty stomach or between meals to maximize its absorption capacity. When used for detoxification purposes, such as after consuming questionable food or alcohol, taking it as soon as possible is advisable.

Activated charcoal can also be beneficial for digestive issues like bloating or gas; in such cases, taking it an hour before or after meals may offer relief. If you're using activated charcoal for teeth whitening, brushing with it before regular toothpaste or after meals can be effective.

Always follow the recommended dosage and guidelines on the product you're using, and it's essential to consult with a healthcare professional, especially if you're on medications, pregnant, or have specific health concerns. Timing matters, so integrating activated charcoal into your routine thoughtfully ensures you make the most of its versatile and beneficial properties.

How Much Activated Charcoal to Take?

Determining the right amount of activated charcoal to take is crucial for reaping its benefits while ensuring safety. The recommended dosage varies based on factors such as age, weight, and the specific purpose for taking it. For general detoxification or digestive issues, a common guideline is 500 to 1,000 milligrams taken an hour before or after meals.

However, when used for acute situations, such as accidental ingestion of toxins, healthcare providers might administer higher doses in a controlled environment. It's paramount to follow product-specific instructions, as activated charcoal supplements come in various forms like capsules, powder, or liquid, each with its concentration.

As a general precaution, it's advisable to start with a lower dose and gradually increase if necessary. Always consult with a healthcare professional before incorporating activated charcoal into your routine, especially if you are on medications or have pre-existing health conditions, to ensure its safe and effective use.

How to Make Activated Charcoal?

Making activated charcoal at home can be a fascinating DIY project. Here's a simplified guide to creating your activated charcoal:

Materials Needed:

  1. Organic material (e.g., coconut shells, wood, or peat)

  2. A metal container with a lid

  3. Heat source (e.g., a campfire or gas stove)

  4. Baking sheet

  5. Water

  6. Airtight container


 1. Collect and Crush Organic Material: 

Begin by collecting your chosen organic material and crushing it into small pieces or powder.

 2. Heat the Material: 

Place the crushed organic material into a metal container and heat it over a flame or gas stove until it becomes red-hot. This process is called pyrolysis and removes impurities from the material.

 3. Seal the Container: 

Once the material is red-hot, quickly cover the container with a lid to limit the oxygen supply. This initiates the activation process.

 4. Cool and Rinse: 

Allow the container to cool completely, and then open it. The material should now be charred but not ash-like. Rinse it thoroughly with water to remove any remaining impurities.

 5. Dry and Store: 

Spread the activated charcoal on a baking sheet to dry, then store it in an airtight container for future use.

*Please note that making activated charcoal at home can be potentially hazardous and may not produce medical-grade charcoal. It's best to purchase activated charcoal for medicinal or consumption purposes.

When to Take Activated Charcoal for Detox?

The timing of taking activated charcoal for detox purposes can vary. Some people take it on an empty stomach, while others prefer taking it with meals to minimize potential gastrointestinal discomfort.

Suppose you're using activated charcoal for detoxification. In that case, it's advisable to follow the recommendations on the product label or consult with a healthcare professional for personalized advice.

Does Activated Charcoal Make You Poop?

Activated charcoal can have a mild laxative effect in some individuals, leading to increased bowel movements. This effect is due to the physical presence of charcoal in the gastrointestinal tract, which may irritate the intestines and promote movement. However, it's not a guaranteed outcome, and not everyone will experience this effect.

How Long Does Activated Charcoal Stay in Your System?

The body does not absorb activated charcoal but passes through the digestive system. As a result, it typically stays in your system for a relatively short time, usually a few hours to a day. Its effectiveness in trapping toxins diminishes as it moves through the digestive tract. Hence, its duration of action is relatively short-lived.

What does Activated Charcoal Do For Dogs?

Activated charcoal for dogs serves a similar purpose as it does for humans. It can be used in cases of poisoning or toxin ingestion to help absorb harmful substances in the dog's digestive system.

However, its use should always be under the guidance of a veterinarian.

How Much Activated Charcoal to Give a Dog?

If you're considering giving activated charcoal to your dog, it's essential to consult your veterinarian first. The appropriate dosage for dogs can vary based on factors such as the dog's size, weight, and the reason for administration. In cases of potential poisoning, your vet will guide the proper dosage and administration method.
