Private label protein powder manufacturer in Spain (EU)

Protein powder is the product most sports nutrition brands launch first, and the one where the label claims are easiest to get wrong. The raw material is the same one your competitors buy, so the product does not win on the ingredient. It wins on taste and mixability, on format, and on a label that says something true and legal. This guide covers what matters before you manufacture protein powder for your brand, and includes a calculator that tells you which EU protein claims your formula can carry.

What private label protein manufacturing means

Private label protein means launching your own protein powder on a formula already validated by a GMP laboratory, which manufactures, packs and labels it under your brand. You decide the positioning, the packaging and the channel. The manufacturer supplies the validated formula, certified raw materials and quality documentation for every batch.

It is the fastest route into sports nutrition for a new brand, for the same reason it is in private label manufacturing generally: the formula is already stabilised and the line already runs it, so there is no development cycle to wait out. For the full comparison between the two models, see OEM versus private label.

Choosing the protein

The first decision is which protein, and it is a market decision before it is a technical one. Whey (concentrate, isolate or hydrolysate) remains the reference for the gym and performance buyer. Plant proteins (pea, rice and blends of them) open the vegan and dairy-free customer. We compared the two on demand, nutrition and certifications in whey vs. plant protein, so here we only add what changes on the manufacturing side:

• Allergens. Milk and products thereof (including lactose) are on the list of allergens in Annex II of Regulation (EU) 1169/2011. On the label, the allergen must be emphasised in the list of ingredients with a typeset that clearly distinguishes it from the rest, for example in bold. Plant proteins do not escape this: soy, for instance, is on the same list.
• Taste and mixability. Plant proteins usually need more work on flavour and texture than whey. Ask your manufacturer what has actually run on their line, not what is theoretically possible.
• Protein per serving. It is the number your buyer compares, and it also decides which claims you can use. That is what the next section is about.

The label: when you can say “source of protein” or “high protein”

This is where a protein launch gets into trouble most often, so it is worth being precise. In the EU, protein claims are not marketing copy. They are nutrition claims with a numerical condition, set in the Annex to Regulation (EC) 1924/2006:

• “Source of protein” only where at least 12 % of the energy value of the food is provided by protein.
• “High protein” only where at least 20 % of the energy value is provided by protein.

The condition is a share of the energy, not of the weight. Two consequences follow:

1. Energy is calculated with fixed factors, set in Annex XIV of Regulation (EU) 1169/2011: protein and carbohydrate 4 kcal (17 kJ) per gram, fat 9 kcal (37 kJ), fibre 2 kcal (8 kJ). A formula with a lot of fat or sugar can carry a fair amount of protein per 100 g and still miss the threshold.
2. The claim refers to the food as consumed. Article 5(3) of Regulation 1924/2006 says claims refer to the food ready for consumption in accordance with the manufacturer’s instructions. If your instructions say to mix the powder with water, the percentage is the same as the powder’s, because water adds no energy. If they say to mix it with milk, the calculation must be made on the prepared drink.

Check your formula

Enter the values per 100 g of your product as it will be consumed. The calculator works out the energy with the Annex XIV factors and tells you which claims the formula supports. The figures below are an example, not a product of ours: replace them with yours.

The three protein health claims

On top of the nutrition claims, Regulation (EU) 432/2012 authorises three health claims for protein:

• Protein contributes to a growth in muscle mass.
• Protein contributes to the maintenance of muscle mass.
• Protein contributes to the maintenance of normal bones.

All three carry the same condition: they may only be used for food which is at least a source of protein, as defined above. Below 12 % of the energy from protein, none of them can go on the label.

Three practical rules that follow:

1. Do not paraphrase. Authorised claims are fixed wording. Copy the exact text for your market’s language from the EU Register of nutrition and health claims, not from a competitor’s label.
2. Decide the threshold at formulation, not at design. Whether you reach 12 % or 20 % is decided by the formula and the preparation instructions, not by the copywriter.
3. Check the wording at print time. Verify against the register before every label revision, not once at launch.

The general framework behind all of this is covered in health claims and supplement labelling in the EU.

Formats

Protein is a high-dose product: a single serving is a full scoop, and that drives the format decision.

• Tub. The category standard for whey and the one the gym buyer expects to see on the shelf.
• Doypack. Lighter to ship, cheaper to pack and well suited to online sales and refills.
• Single-serve sticks. Ideal for trial sizes, gyms and travel, and they solve dosing for the customer. Higher packaging cost per gram of product.

We compared the economics of each format in the most in-demand supplement formats, and format is also the main driver of minimums, covered in the MOQ guide.

What to ask a protein manufacturer

Beyond the general checklist in how to choose a supplement manufacturer, protein has a few specific questions worth asking in writing:

• Certificate of analysis per batch for the protein raw material, and what the specification covers.
• How allergens are managed on the line, especially if you sell a plant protein as dairy-free and the same plant also handles whey.
• Whether the line has run your intended flavour and format, not just whether it could.
• Who checks your label before printing, including the protein claim against the actual analysis of the batch.
• Anti-doping assurance, if you sell to competing athletes. Our commitments are set out in our quality, food safety and anti-doping policy, published on About us.

How to start

The order of decisions: customer → protein (whey, plant or both) → protein per serving and the claim it supports → flavour → format → initial volume. Taken in that order, the label and the shelf price largely resolve themselves.
