The claimEvidence C · limited
Detox / cleanse programs flush accumulated toxins
The evidence
The liver (Phase I/II) and kidneys clear metabolic waste 24/7; Klein & Kiat 2015 review found no rigorous RCT support — short-term weight loss is just water and bowel contents.
Why the claim spreads
'Toxins' is kept deliberately vague (never named), which makes the claim unfalsifiable and the product universally appealing; juice/cleanse brands lean on post-indulgence guilt.
