Is Caffeine legal in United Kingdom?
- Legal status
- Caffeine is legal everywhere as an ordinary food and beverage ingredient; the notable UK status is a mandatory high-caffeine warning label. Retained Regulation (EU) No 1169/2011 (as given effect by the Food Information Regulations 2014) requires drinks containing more than 150 mg of caffeine per litre, other than those based on coffee or tea, to bear the statement “High caffeine content. Not recommended for children or pregnant or breast-feeding women” with the caffeine amount in mg per 100 ml, in the same field of vision as the product name.
- Consequences if caught
- No penalty attaches to ordinary caffeinated foods, drinks or coffee; obligations fall on food businesses, with trading-standards enforcement of the mandatory high-caffeine labelling rather than any consumer offence.
- If prescribed or medical
- n/a — a food ingredient
- Documentation
- Ordinary caffeinated products need no documentation; drinks above 150 mg/L must carry the prescribed “High caffeine content” statement and quantified caffeine declaration.
