Detox drinks myth: do they really flush out toxins?
Detox drinks myth: do they really flush toxins out of your body? See what the research says about cleansing, weight loss and safety risks.
The 30-second summary
- No convincing research shows that detox drinks or diets remove toxins from your body or help you manage your weight.
- Your liver, kidneys, gut and lymphatic system already do the cleaning.
- Main limit: the few studies are small and low quality, there are no randomized trials in people, and no long-term studies.
The idea that detox drinks clean toxins out of your body is a popular myth: there is no convincing research showing they do. A 2015 review found no compelling evidence that detox diets remove toxins or help with weight management, and the US National Institutes of Health (NIH) repeats that conclusion in its 2025 guidance. The real cleaning is done by your own body.
Here we look at what detox drinks are, why so many people feel they work, what the research says about weight loss, and the possible harms.
The popular claim
«Detox drinks cleanse your body of toxins»
Myth
There is no convincing research showing that these drinks remove toxins from the body. Your body already does that job through the liver, kidneys and digestive system.
Why do people believe it?
Detox products are marketed heavily; the 2015 review notes that the detox industry is booming. These diets and drinks are promoted as ways to remove toxins, lose weight or improve health. And many people see the scale drop quickly in the first days, which feels like proof that something is being flushed out.
But that early drop comes from eating fewer calories, not from toxins leaving the body. The NIH cites a 2017 review saying juicing and detox diets can cause initial weight loss because of low calorie intake, but tend to lead to weight gain once a person goes back to a normal diet.
What does the evidence say?
The key study is a 2015 critical review by Klein and Kiat in the Journal of Human Nutrition and Dietetics. It found very little clinical evidence for detox diets, despite a booming industry. A handful of studies reported that commercial detox diets boosted liver detoxification or removed persistent organic pollutants, but they were small and had flawed methods. To the authors' knowledge, no randomized controlled trials had tested commercial detox diets in humans.
In 2025, the US National Center for Complementary and Integrative Health, part of the NIH, reached the same view: only a small number of studies in people, of low quality, and no studies on long-term effects. It also warns that some unpasteurized juices used in detoxes can make people sick, and that laxatives in detox programs can cause diarrhea leading to dehydration.
A 2026 mini-review in Frontiers in Nutrition on diet and detox teas found minimal demonstrated benefit. Multiple reports linked these teas to serious problems, including electrolyte disturbances, heart and blood vessel events and liver injury, and lab analyses found undeclared drug ingredients and high levels of stimulants in some products. Meanwhile, HPRC, a US military health resource, noted in 2020 that your liver, kidneys, lymphatic system and gut are all essential to detoxification.

The takeaway
Your liver and kidneys already remove toxins; talk to your doctor before trying any detox product.
But keep in mind
- The main review dates from 2015 and found no randomized controlled trials of commercial detox diets in people, so the claim has never been put to a strong test.
- The few studies that reported benefits, such as better liver detox or removal of certain pollutants, were small and had flawed methods, so they can't be relied on.
- No studies have looked at the long-term effects of detox programs, whether good or bad.
- The harms of detox teas come mostly from case reports and lab tests of products; they show what can happen, not how often. Some products also don't contain what their labels say.
FAQ
What are detox drinks?
They are part of diets and programs called "detoxes" or "cleanses", such as juices and herbal teas, promoted as ways to remove toxins, lose weight or improve health. There is no convincing research supporting these claims.
Do detox drinks work for weight loss?
You may lose weight at first because you take in fewer calories, but a 2017 review cited by the NIH found the weight tends to come back once you return to normal eating. A 2026 review of detox teas found only limited support for weight loss.
Are detox drinks and teas harmful?
Some can be. Multiple reports have linked diet and detox teas to serious problems such as body salt (electrolyte) imbalances, heart problems and liver injury, and some products contained undeclared drug ingredients. Laxatives in detox programs can cause diarrhea and dehydration, and unpasteurized juices can make people sick.
How does your body get rid of toxins on its own?
Your body detoxifies itself, without outside help, by getting rid of wastes through urine, stool and sweat. Your liver, kidneys, lymphatic system and gut are all essential to this job.
