    Is melatonin legal in Europe? Country-specific access

    There is no single European answer that covers every melatonin product. Prescription medicines, authorized nonprescription medicines and food supplements can have different rules. The examples below cover the United Kingdom, Germany and Sweden; they are not a complete guide to every European country or to personal imports.

    United Kingdom: prescription access

    NHS identifies melatonin as prescription-only. A product sold without a prescription elsewhere does not establish the same supply route in the UK. The relevant question is whether the exact medicine can be lawfully supplied for the intended patient and use. [1]

    Germany: medicines and food supplements coexist

    Germany’s BfR describes both prescription melatonin medicines and melatonin-containing supplements sold in shops and online. It warns that some supplements contain amounts exceeding those in medicines. This description of the market is not a blanket authorization for any imported formula, dose or treatment claim. [2]

    Sweden: nonprescription use has a defined purpose

    The Swedish Medical Products Agency explains that nonprescription melatonin is used for jet lag in adults aged 18 and over, generally for a short course of no more than four to five days. Prescribed treatment for a child is a separate situation. OTC availability does not mean approval for every sleep problem or age. [3]

    Check the destination and exact product

    Imagine a traveler sees a gummy available in Germany and plans to buy the same product elsewhere. Check the destination’s medicines regulator or pharmacist for the formulation, supply category and import conditions. Do not infer Europe-wide legality from a marketplace listing or from one country’s rules. [2][3][1]
