Activated charcoal juice, also called “black lemonade” or charcoal detox water, became popular as a trendy cleanse drink. Activated charcoal does have a real medical use, but drinking it daily as a detox is a different matter. Here is what activated charcoal actually does, the claims made for charcoal juice, the risks, and safer alternatives.
What is activated charcoal?
Activated charcoal is a fine black powder made from carbon-rich materials such as coconut shells or wood, heated to create a very porous surface. In the gut, that surface can bind (adsorb) certain substances so they pass out of the body instead of being absorbed.
That is why hospitals sometimes use it in emergencies for certain types of poisoning or drug overdose, given by medical staff within a short time window. This medical use is very different from adding a spoonful to juice every morning.
Common claims about charcoal juice
Charcoal drinks are often promoted for:
- Removing toxins from the body
- Reducing bloating and gas
- Easing hangovers
- Supporting weight loss
- Improving skin
What the evidence says
- Toxins: activated charcoal only binds substances that are still in the gut. It does not pull toxins out of your blood, liver or tissues. Your liver and kidneys continue to do that work, and there is little evidence that detox products improve on it (NCCIH).
- Bloating and gas: a few small studies suggest charcoal may reduce intestinal gas for some people, but the evidence is limited and inconsistent.
- Hangovers: charcoal does not bind alcohol well, so it is unlikely to help.
- Weight loss: there is no good evidence that charcoal causes fat loss.
- Skin: there is no good evidence that drinking charcoal improves skin.
Risks and side effects
- Interferes with medication: charcoal can bind medicines, including the contraceptive pill, and stop them working properly. If you take any medication, do not use charcoal drinks without speaking to a doctor or pharmacist.
- Binds nutrients: it may reduce absorption of some vitamins and minerals from food eaten at the same time.
- Constipation and black stools: common side effects. Large amounts can, rarely, contribute to bowel blockage.
- Not suitable for everyone: people with digestive conditions, slow gut movement, recent gut surgery, or who are pregnant or breastfeeding should avoid it unless advised by a doctor.
Is charcoal juice ever worth drinking?
For most people, the risks of regular charcoal drinks outweigh the unproven benefits. If you want to reduce bloating, improve digestion or feel less sluggish, food-based changes are safer and more effective.
Safer alternatives
- For bloating: slow down when eating, reduce fizzy drinks and very salty food, and try peppermint or ginger tea. See our list of foods that ease belly bloat.
- For digestion: more fibre from vegetables, fruit and whole grains, plus fermented foods. Read about gut-healing fermented foods.
- For a refreshing “detox” drink: lemon water, cucumber and mint water or green tea. Try our DIY detox water recipes or lemon water detox.
- For liver health: cut back on alcohol and eat more liver-friendly foods.
If you still choose to try it
Speak to a pharmacist first if you take any medication. Keep it occasional, never take it within several hours of medicines or supplements, drink plenty of water, and stop if you develop constipation or stomach pain.
Frequently asked questions
Can you drink activated charcoal every day?
Daily use is not recommended because of the risk of interfering with medicines and nutrient absorption.
Does charcoal juice help with a hangover?
Unlikely. Activated charcoal does not bind alcohol effectively. Water, food and rest are the best options.
