In pet health, the greatest regulatory problems often arise not from the formulation but from what a brand says about the product's effects.

A product may have a sound formula and correctly declared ingredients, yet create regulatory risk through a single sentence on the front label, an online product description or an advertisement suggesting treatment of a disease.

Claims should therefore be developed alongside the formula and documentation, rather than added by marketing at the end.

What is a claim in feed law?

In practice, a claim is a statement or form of presentation that attributes particular properties, functions or benefits to a product.

It may appear as:

  • wording on the packaging;
  • a product name;
  • a description of effects;
  • a graphic or icon;
  • emphasis on a particular ingredient;
  • a list of benefits;
  • website content;
  • a social media post;
  • an advertisement;
  • a comment referring to scientific research.

Compliance therefore extends beyond the physical label.

What does Article 13 of Regulation 767/2009 say?

Article 13 of Regulation (EC) No 767/2009 permits particular attention to be drawn to the presence or absence of a substance, a specific nutritional characteristic or process, or a related function.

The conditions matter: a claim must be objective, verifiable by the competent authorities and understandable to the feed user.

The person responsible for labelling must also hold scientific substantiation and provide the relevant evidence when requested by the competent authority. That substantiation must be available when the feed is placed on the market.

Claims are therefore assessed on more than wording. They need support in the actual product.

The boundary between physiology and treatment

The central rule is that feed must not be presented as preventing, treating or curing disease, subject to the exceptions provided by law.

The distinction between a functional statement and a therapeutic one is therefore crucial.

A lower-risk direction: “supports the maintenance of normal joint condition”.

A high-risk direction: “treats joint degeneration”.

A lower-risk direction: “supports normal digestive function”.

A high-risk direction: “treats diarrhoea”.

A lower-risk direction: “supports natural immune mechanisms”.

A high-risk direction: “prevents infections”.

The important qualification is that the word “supports” does not automatically make a claim lawful.

When assessing the boundary with medicinal presentation, also consider Article 4 of Regulation (EU) 2019/6: the definition of a veterinary medicinal product includes substances presented as having properties for treating or preventing disease in animals.

“Supports” is not a shortcut to compliance

This is one of the most common mistakes in the sector. A brand takes an impermissible therapeutic message and replaces “treats” with “supports”. The problem may remain.

For example, “supports the treatment of arthritis” still refers to treatment of a disease. Similarly, “supports the fight against infection” may suggest a therapeutic function even without the word “treats”.

Authorities assess the overall meaning of the communication, not an isolated verb.

The claim must fit the specific product

To substantiate a claim, assess at least:

  • the formulation;
  • the amount of the key ingredient;
  • its chemical or technological form;
  • the target species;
  • the daily portion;
  • the duration of use;
  • the scientific literature.

A claim should not be developed independently of the formula.

If a study reports an effect with 500 mg of a particular extract, while the finished product supplies 20 mg of another extract with different standardisation, citing that publication alone is insufficient.

An ingredient claim is not the same as a product claim

This matters particularly for ingredients with extensive scientific documentation. Research on an ingredient in a particular model does not mean that every product containing it can adopt the publication's full language.

Consider whether:

  • the same substance was used;
  • the dose is comparable;
  • the form and standardisation are similar;
  • the same species was studied;
  • the reported effect can support a claim for the finished product.

This is often where a formal substantiation dossier becomes necessary.

Need to assess claims before printing or launching a campaign?

FoodUP can review a claim together with the formula, dose and evidence base. The assessment covers both the wording and whether the particular product can substantiate it.

Scientific research is not automatic marketing authorisation

A scientific paper addresses a research question. A label or advertisement serves a commercial purpose. These are different contexts.

A study may describe effects on parameters associated with disease, but directly transferring its language to a label may create an impermissible medicinal claim.

The literature should substantiate a lawful claim, rather than supply the most striking sentence from an abstract.

Process and quality claims also need assessment

Risk is not limited to physiological claims. Statements such as:

  • “standardised to 5% of substance X”;
  • “DER 10:1”;
  • “highly bioavailable”;
  • “premium purity”;
  • “no added X”

must also be true and verifiable.

A declared standardisation requires supporting documentation. For a “free from X” statement, assess whether it could mislead and whether it is adequately supported throughout the supply chain.

Omnichannel communication: Instagram claims carry risk too

Regulation 767/2009 defines labelling broadly, including information associated with feed in advertising and on the internet.

The same principles should guide:

  • packaging;
  • the online shop;
  • marketplaces;
  • social media;
  • performance advertising;
  • materials for veterinarians and distributors;
  • commercial presentations.

Removing a problematic claim from the label is insufficient if it remains on the product page.

How should a claim be assessed before publication?

A robust process includes eight steps:

  1. Define the exact claim, not just a general topic such as “immunity”.
  2. Determine whether it concerns nutrition or physiology, or starts to suggest treatment.
  3. Identify the ingredient or product feature intended to support it.
  4. Check the dose and directions for use.
  5. Collect scientific literature and product documentation.
  6. Assess whether the data apply to the finished product.
  7. Review the full visual and verbal context.
  8. Document the decision.

This makes claims part of the regulatory process rather than incidental marketing wording.

Red flags in pet health communication

Particular care is needed with direct references to:

  • treatment;
  • disease prevention;
  • diagnosis;
  • symptom relief;
  • infection;
  • inflammation;
  • pain;
  • named diseases.

Brands can communicate product benefits, but must remain within the applicable legal framework.

FAQ

Is “supports” always safe?

No. The overall meaning matters. “Supports the treatment of disease” still refers to a therapeutic function.

Can scientific studies be cited on a product page?

Scientific evidence may be used, but its presentation must be assessed within the full communication. Citing a study does not automatically permit a medicinal claim for a feed product.

Can a claim concern the ingredient alone?

Yes, but it must not create an impression that the finished product has properties unsupported by its formula, dose and scientific evidence.

Do website claims fall under feed law?

Yes. Online presentation and distance selling are subject to requirements on accuracy and impermissible medicinal properties.

Does every claim require a new study on the finished product?

Not necessarily. The evidence needed depends on the claim, its novelty and whether existing knowledge can be applied to the specific product. A well-constructed dossier based on literature, formulation and dose may be sufficient in some cases. In others, original data will be more important.
