Getting a food supplement onto the European market requires more than a compliant formula. The label must meet specific legal requirements in each Member State, and a translation error can block market authorisation or expose the company to regulatory action by competent authorities.
What EU legislation requires on supplement labels
Regulation (EU) No 1169/2011 on the provision of food information to consumers is the primary framework. For food supplements specifically, Directive 2002/46/EC applies, transposed into national law by each Member State. In practical terms, the label must appear in the official language of the country of sale, or in the official languages where a Member State has more than one.
Mandatory elements include: product name, list of ingredients, recommended doses, statutory warnings ("Do not exceed the recommended daily dose", "Keep out of reach of children"), nutritional declaration, and a statement that the product does not substitute a varied diet. Each of these elements carries regulated terminology. Substituting "food supplement" with "dietary supplement" may seem minor, but in certain markets it introduces legal ambiguity with products regulated under a different framework.
Where technical translation fails most often
Food supplement labelling draws on three distinct domains: nutrition, pharmacology, and food law. Most translation errors do not stem from general linguistic incompetence. They come from a lack of familiarity with the specific regulatory regime.
The most common problems are:
- Unauthorised health claims. Regulation (EC) No 1924/2006 defines which claims are permitted. A translation that uses a stronger verb ("strengthens" instead of "contributes to the normal function of") can constitute an unapproved claim.
- Incorrect units or non-compliant formats. The EU uses SI units. Conversion errors or formats that do not comply with Regulation 1169/2011 lead to immediate rejection.
- Incomplete or loosely worded warnings. Many warnings have fixed wording established in Directives or EFSA opinions. Translating freely, even when the meaning is equivalent, may not satisfy the legal requirement.
- Missing country-specific mandatory statements. Germany, France, and Italy, for example, have national requirements that go beyond the harmonised European framework.
The difference between a standard translation and an ISO 17100-certified one
For regulatory documentation submitted to competent authorities, such as the MHRA in the UK, ANSES in France, or BVL in Germany, a single-linguist translation is not adequate. Authorities expect documentation produced through auditable quality controls.
ISO 17100-certified pharmaceutical translation requires a workflow with at least two independent linguists: a translator and a reviewer. The reviewer checks not only linguistic accuracy but terminological compliance with the applicable regulatory framework. This workflow produces an auditable record of the process, which is relevant when authorities request supporting documentation for a submission.
For labels intended for direct consumer sale, the legal standard is the same. The commercial impact of an error is different, however: a label with non-compliant terminology can be withdrawn from the market by the Member State following a market surveillance check.
For a broader view of how these requirements apply across regulated product categories, the article on drug labelling translation covers the additional layer of requirements that apply to medicinal products.
Preparing the translation brief: what to provide
Proper preparation reduces turnaround time and avoids unnecessary revision rounds. When commissioning translation for food supplement labels, the following should be provided:
- Editable source file (AI, InDesign, layered PDF, or Excel with text strings)
- Ingredient list with INCI nomenclature or chemical nomenclature where applicable
- Internal glossary or brand glossary, if one exists
- Target markets (countries and languages)
- Reference to authorised health claims on the label, with EFSA registration number where available
- An approved label in a reference language, if available
The more regulatory context is supplied, the more precise the translation will be. The translator should not need to infer whether a claim is EFSA-authorised or not.
How M21Global handles supplement label projects
M21Global has over 20 years of experience in translation for regulated sectors, with ISO 17100:2015 certification audited by Bureau Veritas. Food supplement labelling projects follow the Estratégica workflow: three linguists (translator, reviewer, and QA reviewer), two post-delivery revision rounds, and a dedicated project manager.
The team works with terminology glossaries aligned to Regulation 1169/2011, Directive 2002/46/EC, and the EFSA register of authorised health claims. For multilingual projects across several markets, translation memories ensure consistency across language versions. For a sense of how similar quality standards apply to other regulated documents, see the article on medical device documentation translation under MDR.

Frequently Asked Questions
Does food supplement label translation need to be certified for EU sale?
EU legislation does not mandate a specific translation certification, but it requires that labels appear in the official language of the Member State of sale and use the terminology regulated under Regulation 1169/2011. For submissions to competent authorities, an ISO 17100 workflow is the most reliable way to demonstrate documentary rigour.
What are authorised health claims and how do they affect translation?
Authorised health claims are those approved by EFSA and listed under Regulation (EC) No 1924/2006. The translation must reproduce the exact approved wording in the target language. Altering the phrasing, even while preserving the meaning, can constitute an unauthorised claim and result in regulatory non-compliance.
Does the translator need a glossary before the project starts?
It is not mandatory, but it is strongly recommended. A glossary covering ingredient nomenclature, approved claims, and brand terms speeds up the project and reduces the risk of inconsistencies across language versions.
How long does it take to translate a food supplement label?
Turnaround depends on text volume, number of languages, and the quality workflow selected. A straightforward label for a single language can be completed in two to three business days with a full review workflow. Multilingual projects for several markets require earlier planning.
Can M21Global translate supplement labels for all EU markets?
Yes. M21Global works across all official EU languages, with specialist teams in pharmaceutical and regulatory translation covering the major European markets.
