EU food supplement maximum levels: where things stand and how to design for them

One of the most consequential questions in EU supplement formulation has a frustrating answer: how much of a vitamin or mineral can you put in a food supplement? The Food Supplements Directive provides for maximum levels to be set at EU level, but those harmonized maxima have never actually been adopted. The result is a patchwork of national rules that a formula has to navigate, and it shapes how you design a product meant to sell across the EU.

The harmonized maxima that never came

Directive 2002/46/EC anticipated EU-wide maximum (and minimum) amounts for vitamins and minerals in supplements, to be set later by the Commission. Decades on, they still have not been set. So while the permitted list of vitamins, minerals, and their forms is harmonized, the amounts are not — leaving the ceiling to each member state.

National caps fill the gap

In the absence of EU maxima, several member states set their own maximum levels, and they differ — sometimes substantially. A level of a given vitamin that's perfectly acceptable in one country can exceed the national cap in another. Some states publish formal maxima, others work to guidance values or assess case by case. The same formula can therefore be compliant in one EU market and not in its neighbor.

Safety-based reference points

Underlying the national caps are safety considerations — tolerable upper intake levels and intake from the wider diet. Designing with recognized upper safe levels in mind, rather than to the highest national cap, gives a formula a better chance of traveling. The principle is to formulate to a level defensible on safety grounds across markets, not to push to the edge of the most permissive one.

Designing a formula that travels

For a product intended for several EU markets, the practical approach is to know the relevant national caps for each target market and design to the most restrictive that matters — or to plan deliberately for market-specific variants where a single level won't work. Either way, it depends on knowing each nutrient's level against each market's ceiling as you formulate, rather than discovering a breach at notification.

This is general information, not regulatory or legal advice. National requirements differ across the EU and change over time, so confirm current rules with the relevant authority or a qualified regulatory expert before relying on them.

Where Lemoniq fits

Lemoniq checks each nutrient's level against the rules of the markets you select from one structured formula — so a level that exceeds a national cap is flagged as you design, and a formula intended to travel across the EU is built to the ceilings that actually apply.

The takeaway

The EU never set harmonized maximum levels, so national caps differ and a supplement formula has to be designed against the markets it targets. Knowing each nutrient against each market's ceiling — and designing to safety-based levels — is what lets a product travel across the EU without a reformulation at the border.
