Is Melatonin legal in Slovenia?

Formal status

There is no EU-harmonised rule on melatonin in food supplements. It is governed nationally, and member states differ widely - from outright medicine-only treatment to permitted doses of several milligrams. That absence of a common rule is itself the correct starting point.

Slovenia sets no limit in its food supplements rules, whose annex covers only chemical forms of amino acids, carnitine, taurine, nucleotides, choline and inositol. Instead those rules route the question elsewhere: where there is doubt whether a product is a food supplement or a medicine, the medicines legislation applies.

The medicines agency has answered that question. Its expert opinion of 19 December 2019 concludes that a significant effect on physiological functions is achieved at doses of 0.5 mg of melatonin or more, so products at those doses meet the definition of a medicinal product, and that at those levels the safety profile makes them unsuitable for recommendation to the general population. Its borderline-classification guidelines, in the version issued in July 2022, set the limiting daily dose for a food supplement at 0.44 mg. An earlier version of the same guidelines had listed melatonin at zero.

The agency has also applied this at the individual product level: in April 2012 it classified a product delivering 1 mg of melatonin in capsule form as a medicinal product.

Below the threshold, the agency requires specific warnings - that the product is for healthy adults only, not for under-18s, and not before driving within five hours.

Do we sell here?

Not at the moment.

We do not ship to Slovenia, and melatonin is not the reason.

Slovenia does treat melatonin cautiously. Its medicines agency sets the limit for a food supplement at 0.44 mg a day, and regards 0.5 mg and above as meeting the definition of a medicine - so our 1 mg dose sits above the Slovenian line, as it does in several European countries. Slovenian brands work closely to that limit, with sprays and tablets typically at 0.33 to 0.4 mg.

But that is a difference we could address with a reformulation. The reason we do not sell in Slovenia is more fundamental and concerns the hemp extract rather than the melatonin: Slovenian law lists cannabis extracts among its controlled drugs with no threshold at all.

Outlook

The Slovenian figure has been stable since 2019 and the domestic market has organised itself around it very precisely, which makes movement unlikely.

One oddity is worth watching. The agency's guidelines state 0.44 mg, but the expert opinion they cite as their source states 0.5 mg and contains no mention of 0.44 anywhere. In practice 0.44 mg is simply the highest declarable dose that stays below the 0.5 mg line, but the discrepancy is unexplained and a future revision of the guidelines could resolve it in either direction.

The enforcement pattern is also worth following. Slovenia's health inspectorate has repeatedly published consumer warnings about foreign online sellers offering high-dose melatonin to Slovenian consumers, and has said openly that where such a seller cannot be identified it has no means of acting. Whether it acquires stronger tools would be a meaningful change.

Timeline

April 2012

JAZMP decision no. 143-27/2011-8 classifies the product "Melatonin 1 mg — 60 kapsul" as a medicinal product — an individual classification decision at exactly 1 mg per daily dose, in capsule form. Recorded in the NIJZ expert opinion on the safety of melatonin in foods of 3 August 2012; the decision itself is not published.

December 2019

JAZMP expert opinion no. 143-10/2019: "Pomemben vpliv na fiziološke funkcije dosežemo z odmerki 0,5 mg melatonina ali več, zato izdelki s temi odmerki glede na sestavo ustrezajo definiciji zdravila." JAZMP's borderline-classification guidelines (July 2022 version, issued under article 7(2) ZZdr-2) set the limiting daily dose for food supplements at 0.44 mg, citing this opinion; the October 2014 version of the same guidelines had listed melatonin at 0 mg.

October 2024

ZIRS publishes a consumer warning against the food supplement "Melatonin Forte+" (brand CvetNarave), supplied by Lymus s.r.o., Mierova 29, Bratislava, Slovakia, and sold to Slovenian consumers online: "Prehransko dopolnilo vsebuje previsoko vsebnost melatonina (5 mg), zato lahko predstavlja tveganje za zdravje potrošnikov." The measure was a consumer warning only — no recall order, no fine and no seizure followed against the foreign supplier.

May 2025

ZIRS publishes a notice on fraudulent practices in the online sale of CvetNarave and KonopljinCvet food supplements to Slovenian consumers, naming Embro s.r.o., Lymus s.r.o. and Jomlu s.r.o. (all Bratislava) and recording that "z namenom izogniti se uradnemu nadzoru, ta podjetja ne prijavijo svoje dejavnosti pri pristojnem organu… se podjetje zapre in odpre novo podjetje, ki nadaljuje s svojo dejavnostjo". The response was to add the websites to the risky-sites list and advise consumers against purchase. ZIRS's annual reports record that where an online seller cannot be identified, "ukrepanje inšpektorata v takih primerih ni možno".
