Detox, Cleanse and Chelation Claims

Urgent note first

Chelation is a prescription medical treatment for specific metal poisonings, given under supervision. It is not something to start on your own. If you think someone has swallowed a harmful substance, call Poison Help at 1-800-222-1222 (US) or 911 for an emergency; see Poisoning: What to Do First.

Three different things with similar names

Labels used: approved medicine (prescription chelators, FDA-regulated, used in medicine for metal poisoning), no good evidence of benefit (detox programs for removing toxins), evidence of harm (in some cases below), and marketing claim.

Detox and cleanse programs

The National Center for Complementary and Integrative Health (NCCIH) describes detoxes and cleanses as regimens suggested to remove toxins, lose weight or promote health, including fasting, juice-only diets, supplements, herbs, colon cleansing and reducing environmental exposures. [1]

What the research shows, per NCCIH:

• There have been only a small number of studies in people, and they were of low quality, with design problems, few participants, or no peer review. [1]


• A 2015 review found no compelling research that "detox" diets work for weight management or for eliminating toxins from the body. [1]


• A 2017 review said juicing and detox diets can cause initial weight loss through low calorie intake, but weight tends to return once a normal diet resumes. [1]


• There are no studies of long-term effects. [1]

Safety points from the same source:

• The FDA and Federal Trade Commission have acted against companies selling detox products that contained hidden ingredients, made false claims to treat serious disease, or (for colon-cleansing devices) were marketed for unapproved uses. [1]


• Colonic irrigation has limited clinical evidence behind it, and colon cleansing can have serious side effects, more likely in people with gut, kidney or heart disease. [1]


• Drinking large amounts of water and tea while not eating for days can cause dangerous electrolyte imbalances. [1]

One example of hidden ingredients: an FDA warning letter in 2019 said laboratory analysis of a product sold as "Golean Detox" found undeclared sibutramine and phenolphthalein. [3] Sibutramine is a drug that was withdrawn from the US market after data showed an increased risk of heart attack and stroke. [3]

Plain claims such as a "mineral detoxifier removes the metals and toxic molecules from the body" appeared in marketing cited in an FDA warning letter to another company in 2022. [4] A claim on a label or website is a marketing claim, not evidence.

Chelation: real medicine, wrong use

In medicine, chelation uses certain chemicals to remove heavy metals and has been used to treat metal poisoning. [2] All FDA-approved chelation products require a prescription because they can be used safely only under a clinician's supervision. [2] NCCIH notes that the CDC recommends chelation therapy for removing toxic metals in some specific serious cases. [1]

Poison-control experts add that:

• Removal from the exposure is always first-line for suspected metal toxicity; chelation is almost never first-line. [5]


• Chelation during ongoing exposure is without benefit and potentially dangerous. [5]


• Metal toxicity does not typically occur without an extraordinary exposure. [5]


• Chelation carries risks, including unintended removal of metals the body needs. [5]


• It is described as inappropriate, ineffective and potentially dangerous for autism spectrum disorder. [5]

Why the claims feel convincing

• A provoked urine test can show "high" metals simply because a chelator was given. [6] See Limits of Consumer Environmental and Toxin Testing.
• Feeling better after a diet change or fasting is not evidence that toxins left the body.
• Real environmental concerns exist, such as lead in older homes, and are best handled by reducing the source; see Practical Exposure Reduction: What Evidence Supports.

What to do instead

Talk with a health professional about any detox or cleanse you are considering, as NCCIH advises.
