When can you call a food “high protein” in the EU?

7 min read

Protein has moved beyond sports nutrition and into cereals, yoghurts, snacks, drinks and ready meals. In Germany, Mintel found that almost one-quarter of cereal consumers considered protein content when choosing a product. As protein becomes a more valuable marketing proposition, you need to know whether your product can legally carry a “high protein” claim before the wording reaches its packaging or advertising.

For a food business, “high protein” can therefore be more than a line of packaging copy. It can influence:

  • how the product is formulated;
  • where it sits within a category;
  • which consumers it targets;
  • how retailers describe it;
  • what appears on the front of the package; and
  • which health or performance messages the marketing team wants to develop.

But the commercial value of the wording is also why it has a legal meaning.

You cannot call your product “high protein” simply because it contains protein, contains more protein than a previous recipe or displays an impressive number of grams on the package. Under EU rules, at least 20% of the food’s total energy value must come from protein.

The calculator in this guide checks that relationship.

Written for food founders, product developers, marketers and Regulatory Affairs teams preparing protein claims for EU labelling, websites and advertising.

What is a protein claim?

The nutrition declaration reports how much protein the food contains. A protein claim uses that nutritional characteristic to promote the product.

For example:

InformationRole
Protein expressed in grams in the nutrition declarationReports the product’s protein content
“Source of protein”Promotes the food as having a beneficial nutritional property
“High protein”Promotes a higher level of that nutritional property
“Protein contributes to the maintenance of muscle mass”Connects protein with an authorised health effect

This is the difference between a label and a claim.

The food label is the complete set of information presented with the product. It may contain the product name, ingredient list, allergen information, nutrition declaration, instructions and voluntary marketing messages.

A claim is a particular message within that presentation. It states, suggests or implies that the food has a beneficial nutritional property or a relationship with health.

“High protein” is therefore a nutrition claim that may appear on a label, website, retailer listing or advertisement.

Why is the high-protein claim regulated?

A prominent protein message can affect how consumers compare products. It may also create a wider impression of fitness, health or nutritional quality.

EU rules give the claim a common meaning. A food business that invests in formulation and evidence to reach the threshold should not have to compete with another product using the same message without meeting the same condition.

The European Commission explains that nutrition and health claims should be clear, accurate and based on evidence. The rules are intended to protect consumers while creating common conditions for food businesses operating across the EU.

Protein claims are also checked in practice.

During a Dutch enforcement campaign, the national food authority reviewed 54 products promoted using protein-related wording on the front of the package. It also reviewed the corresponding websites.

The authority reported misleading or seriously misleading communication for 25 products. The outcomes included official warnings, administrative fines and required changes to packaging and website information. The authority published its findings in 2024.

The commercial opportunity and regulatory risk are therefore connected: the more prominently a food business uses protein to position a product, the more important it becomes to establish what the product can actually claim.

What are the EU requirements for a “high protein” claim?

The legal condition appears in the Annex to Regulation (EC) No 1924/2006.

A food may use a “high protein” claim, and another claim likely to have the same meaning for consumers, only when at least 20% of its energy value is provided by protein.

Alternatively, if your product does not meet this threshold, the same Regulation establishes a lower condition for “source of protein.”

ClaimRequired proportion of energy from protein
Source of proteinAt least 12%
High proteinAt least 20%

The important word is energy.

The condition is not based on a universal number of protein grams. It asks what proportion of this particular product’s total energy is supplied by protein.

Fat, carbohydrates, fibre, polyols and other energy-providing components affect that relationship. Two products containing the same quantity of protein may therefore produce different results.

That is what the calculator checks.

Check whether your product qualifies for a high-protein claim

Enter the protein and total energy values from your product’s nutrition information into rukola’s calculator.

Both values must use the same basis. If protein is entered per 100 g, the energy value must also be entered per 100 g.

Use protein and energy values expressed on the same basis. Do not combine a per-serving value with a per-100 g or per-100 ml value.

This calculator provides an initial screening based only on the information entered. Products close to a threshold may require assessment of unrounded values, supporting evidence, normal product variability and the final nutrition declaration. It is not legal advice.

How the calculator works

Under Regulation (EU) No 1169/2011, one gram of protein provides 4 kcal, or 17 kJ, for the calculation of a food’s energy value.

The calculator:

  1. determines the energy provided by the entered quantity of protein;
  2. compares it with your product’s total energy value;
  3. calculates the percentage of energy provided by protein; and
  4. compares the unrounded result with the 12% and 20% thresholds.

The result displayed can be rounded to one decimal place, but the calculator uses the unrounded result when determining which threshold has been reached.

What if the result is close to 20%?

A result of exactly, or only slightly above, 20% deserves further attention.

Declared nutrition values are average values. Depending on your product, they may be based on laboratory analysis, calculations from ingredient values or generally established data.

The final assessment may need to consider:

  • the current formulation;
  • unrounded nutrition values;
  • the evidence supporting the values;
  • normal ingredient and production variability;
  • rounding used in the nutrition declaration; and
  • whether the calculation remains supported after a formulation change.

The European Commission provides guidance on tolerances and rounding for declared nutrition values.

The calculator can establish the initial mathematical result. It cannot determine whether the complete evidence base reliably supports a borderline claim.

Is “protein-rich” different from “high protein”?

Changing the wording does not necessarily change the applicable condition.

Regulation (EC) No 1924/2006 covers both the named claim and claims likely to have the same meaning for consumers.

Depending on their wording and presentation, this may include expressions such as:

  • protein-rich;
  • protein-packed;
  • packed with protein;
  • loaded with protein; or
  • an excellent source of protein.

These expressions should not be treated as automatic alternatives when your product fails to reach the high-protein threshold.

The complete presentation matters. A prominent protein message on the front of a package can communicate a nutritional benefit even when it does not use the precise words “high protein.”

Does a high-protein product automatically qualify for muscle claims?

No. “High protein” is a nutrition claim because it describes a nutritional property of the food.

A statement connecting protein with a health function is a health claim and follows additional rules.

Regulation (EU) No 432/2012 includes authorised claims stating that:

  • protein contributes to growth in muscle mass;
  • protein contributes to the maintenance of muscle mass; and
  • protein contributes to the maintenance of normal bones.

These health claims may be used for foods that are at least a source of protein, subject to the general and specific requirements governing their use.

Qualifying as high protein does not permit every statement about strength, recovery, athletic performance or body composition. Review the exact wording and surrounding presentation separately.

Also check your advertising and influencer content

And while you are at it, keep advertising, social media and influencer content on the checklist too.

EU food compliance for the characteristics of a food usually does not stop at the package. The same protein message may need review wherever consumers encounter it, including:

  • packaging;
  • a product page;
  • a retailer listing;
  • an advertisement;
  • social media;
  • influencer content; or
  • other commercial material.

That is also why the Dutch enforcement campaign looked at product websites as well as packaging. Protein claims still sit inside the wider EU labelling picture—see What information is required on an EU food label?.

Frequently asked questions

How much protein does a food need to qualify as high protein in the EU?

At least 20% of the food’s total energy value must come from protein. This is not the same as containing 20 g of protein or being 20% protein by weight.

How do I calculate whether a food is high in protein?

Enter your product’s protein and total energy values into rukola’s calculator above. It calculates the proportion of the product’s energy provided by protein and compares it with the EU thresholds.

Is “high protein” based on protein grams or calories?

It is based on energy. Protein grams are used to determine the energy supplied by protein, which is then compared with the product’s total energy value.

What is the difference between “source of protein” and “high protein”?

“Source of protein” requires at least 12% of the food’s energy to come from protein. “High protein” requires at least 20%.

Can I call my product “protein-rich” instead?

Not necessarily. EU rules also cover claims likely to have the same meaning for consumers. “Protein-rich” may communicate a high-protein claim depending on its context and presentation.

Can I use “high protein” on my website or social media?

Only when your product meets the applicable conditions. EU nutrition and health-claim requirements apply to advertising and commercial communications as well as packaging.

What can happen if a protein claim is misleading?

Possible outcomes can include required corrections, packaging or website changes, formal warnings and financial penalties. The precise enforcement response depends on the authority, jurisdiction and circumstances.

Does “high protein” mean the entire product is healthy?

No. It means that the product meets a specific condition concerning the proportion of energy provided by protein. It does not describe the product’s complete nutritional profile.

Can a high-protein product say it builds muscle?

Only authorised health claims may be used, subject to their conditions and the wider requirements of Regulation (EC) No 1924/2006. Stronger or altered statements may communicate a different effect.
