How Does Activated Charcoal Work?

Activated charcoal’s porous structure allows it to adsorb toxins and chemicals in the gastrointestinal tract. Upon ingestion, it binds to certain substances which in turn prevents their absorption into the blood. This is very much the case in a medical setting which sees use of the charcoal for treatment of certain types of poison or overdose. But also in these applications, it is dependent on when it is given and what the substance is.

Can Activated Charcoal Support Digestive Health?

Activated charcoal has at times been used to reduce digestive issues like gas and bloating. What it does is it binds to gas-producing elements in the intestines which in turn may relieve symptoms. Also, there is not a great deal of science behind its use for general digestive health and we need more research to see how effective it really is.

Could Activated Charcoal Affect Cholesterol Levels?

Research indicates that activated charcoal might influence cholesterol levels by binding to bile acids in the gut, which are then excreted from the body. This process may cause the liver to use up extra cholesterol for the production of more bile acids which in turn may lower blood cholesterol levels. But at this point the evidence is still out and we require more studies to determine its value in cholesterol management.

What do people use Activated Charcoal for?

• Medical Treatment: Activated charcoal is used in emergency situations for certain types of poisonings or overdoes which it does so by preventing the intake of harmful substances.
• Digestive Aid: At times it is used for gas and bloating which in fact is a claim that isn’t well supported by science.
• Water Filtration: Activated charcoal used in water filters which in turn improves taste and safety.
• Skin Care: Due to its adsorptive properties, it is included in various skincare products aimed at removing dirt and oil from the skin.

Are you aware of any side effects or precautions?

While it is true that activated charcoal is for the most part safe for short term use it does cause some side effects like constipation, black stools, and in rare cases gastrointestinal blockages. Also it may put a stop to the absorption of medications and nutrients if taken at the same time. Also it is best to check with your health care provider before starting activated charcoal which is also recommended for people on medication or with health issues.

How Should Activated Charcoal Be Used?

Is it safe to use activated charcoal over the long term?
