Slimming teas divide into three functional categories: stimulant teas (caffeine/EGCG — real but modest metabolic effect ~80 kcal/day, Dulloo 1999), laxative/diuretic teas (senna, dandelion — produce water and stool loss only, no fat loss), and flavoured teas with no active weight management ingredients. EFSA has not authorised weight loss claims for any slimming tea ingredient. FSA has issued warnings on senna-based detox teas.
UK food supplement regulation under the Food Supplements Regulations 2003 (as retained EU law) and MHRA oversight. What regulation covers: permitted ingredients lists, maximum safe doses, labelling requirements, health claims under EFSA Regulation 1924/2006. What it does not cover: pre-market efficacy testing. The regulatory gap: supplements are not required to prove they work before sale — only that they are safe. This creates a market where ineffective products are legal. MHRA enforces against products making unauthorised medicinal claims.
