National maximum levels for vitamins and minerals across the EU

A multivitamin that is perfectly legal in one EU country can be over the limit in another — same formula, same doses, different verdict. It surprises manufacturers who assume the single market means a single rulebook. For maximum levels of vitamins and minerals in supplements, it does not.

The harmonisation that never happened

Directive 2002/46/EC anticipated that maximum and minimum amounts of vitamins and minerals in food supplements would be set at EU level. In practice, those harmonised maximum levels have not been established. The framework exists; the numbers do not.

Into that gap, individual member states have stepped. Many have set their own national maximum permitted levels for nutrients in supplements, and those levels are not the same from one country to the next.

Why national limits diverge

National authorities set maximum levels using a risk-based logic: the safe upper level for a nutrient, minus the intake people already get from the general diet and from fortified foods, with a margin for variation across the population. Because dietary intake and the assumptions behind it differ between countries, the resulting maximum for supplements differs too.

The consequence is a patchwork. For some nutrients the limits are broadly similar across the EU; for others they vary widely, and a dose that is routine in one market is not permitted in another.

The EFSA upper level is not the limit

It is tempting to treat the EFSA tolerable upper intake level as the ceiling and assume anything below it is fine everywhere. That is not safe. The EFSA upper level is the science-based safety reference; the legal maximum that applies to your product is the national maximum permitted level of the market you are selling into — which is often set below the EFSA figure precisely because it accounts for intake from the rest of the diet.

So there are effectively two numbers to keep in view: the safety reference and the market's legal maximum. The legal maximum is the one that determines whether you can sell.

What this means for a multi-market product

If you sell the same supplement across several EU countries, you face a choice. You can maintain separate formulas tuned to each market's limits — more products to manage, more documentation, more room for error. Or you can formulate to the strictest applicable limit, so a single formula is compliant everywhere you sell it.

The single-formula approach is simpler to manage but may mean dosing below what a less strict market would allow. The multi-formula approach maximises the dose per market but multiplies the complexity. Either way, the decision has to be made with the actual national limits in front of you — not a guess.

The moving-target problem

National maximum levels are not static. They are reviewed and updated, and the list of markets you sell into changes as the business grows. A formula validated against last year's limits, or against the three countries you sold in then, is not automatically valid against today's limits or the five countries you sell in now.

This is what makes manual tracking so fragile. Holding a spreadsheet of limits per nutrient per country, keeping it current, and re-checking every formula against it whenever a dose changes or a market is added is exactly the kind of repetitive, high-stakes task where errors creep in unnoticed.

Limits, forms, and claims are linked

Maximum levels do not stand alone. The amount measured against a limit is the elemental nutrient, which depends on the form you used. And the same amount also drives claim eligibility. So a single dose decision touches the form, the limit in each market, and the claims the product can carry — all at once.

Treating these as separate manual checks is how a formula ends up compliant on one axis and not another.

Checking limits as you formulate

The robust approach is to select the markets a product is for and let the system check the cumulative amount of each nutrient against each market's maximum as you build the formula. Adjust a dose, and you see immediately whether you are within the limit for every selected market — and where the strictest market sets the real ceiling.

Compliance stops being a country-by-country spreadsheet exercise at the end and becomes a live constraint while the formula is still on the screen.

The takeaway

There is no single EU maximum level for vitamins and minerals in supplements — there are national limits that diverge between member states, and they sit below the EFSA safety reference more often than not. Selling across the EU means knowing the limit in each market and formulating to the strictest one that applies, against numbers that keep changing. The manufacturers who handle this well check it continuously, per market, as they formulate.

Lemoniq checks each nutrient against the maximum levels of every EU market you select, live as you formulate — so you can see the strictest applicable limit and stay compliant across the single market without separate spreadsheets. We solve this exact problem. See how it works
