EU vs US: generating the right panel from one formula

Take one supplement and sell it in both the EU and the US, and you need two different labels — not because the product differs, but because the markets present it differently. The EU nutrition labeling and the US Supplement Facts panel diverge in format, in the reference values behind the percentages, and in the rules for what goes where. Generating the correct panel for each market from a single formula is exactly what a market-aware system does. Here is how the two differ and how software handles both.

Two markets, two panels

The EU and the US each have their own way of presenting a supplement's composition. The US uses the Supplement Facts panel, with its specific layout, its Daily Values, and its conventions for dietary ingredients. The EU presents nutritional information under its own rules, with its own reference values (the NRVs) and format. The same nutrients, at the same amounts, appear differently on each market's label.

So a product sold in both markets needs both panels — each correct for its market — derived from the same underlying formula.

Different reference values, different percentages

A key difference is the reference values behind the percentages. The percentage of a nutrient's reference intake is calculated against the market's reference value — and the EU's reference values differ from the US Daily Values. So the same amount of a nutrient yields a different percentage on the EU label than on the US label. The amount is the same; the percentage is market-specific.

A system that holds both sets of reference values calculates the right percentage for each market automatically, from the same delivered amount — so neither label is wrong.

Different rules and conventions

Beyond the numbers, the rules differ. How ingredients without a reference value are handled, how the panel is laid out and ordered, what must be declared and how — these follow each market's conventions. The US Supplement Facts panel and the EU presentation are not the same template with different numbers; they are different formats following different rules.

Software that knows each market's panel rules generates each one correctly — not an EU panel awkwardly adapted to look American, or vice versa, but each market's genuine panel.

From one formula, both panels

The point is that both panels come from the same formula. You hold the product once, with its real composition; the system applies the EU rules and reference values to generate the EU presentation, and the US rules and Daily Values to generate Supplement Facts. Switch the market, and the correct panel for that market is generated from the shared formula — no separate product, no manual recalculation of percentages, no risk of the two labels describing subtly different products.

This is the multi-market approach applied to the most visible artifact: the label. One formula, the right panel for each market.

Why this matters for going international

For a brand expanding from the EU to the US or vice versa, generating the new market's panel from the existing formula is what makes the expansion fast and safe. You are not recreating the product for the new market or recalculating percentages by hand against unfamiliar reference values — the system produces the correct panel for the new market from the product you already have.

Because panel formats, reference values, and labeling rules differ by market and change over time, confirm the current requirements for your specific products and markets rather than relying on a general summary.

Where Lemoniq fits

Lemoniq generates the correct panel for each market from one formula: it holds both the EU reference values and the US Daily Values, applies each market's panel rules and format, and produces the EU presentation or the US Supplement Facts panel as you switch markets — with the percentages calculated against the right reference values for each. One product, the genuine panel for every market it sells in.

The takeaway

The EU nutrition panel and the US Supplement Facts panel differ in format, reference values, and rules — so a product sold in both needs both panels, each correct for its market. Software that holds the formula once and applies each market's reference values and panel rules generates the right label for each automatically. One formula, the genuine panel for every market, is what makes selling internationally accurate and fast.

Lemoniq generates the EU panel and the US Supplement Facts panel from one formula — each with the right reference values and rules. We solve this exact problem. See how it works
