Whey is the backbone of every sports nutrition brand. But between protein source, flavor, mixability and labeling, a protein powder is won on the details. Here is how to start a whey or plant protein brand, and how to work with a manufacturer.

Protein powder is the best-selling product in sports nutrition. It is used every day by athletes who reorder regularly and stay loyal to a flavor they like. For a brand, it anchors the range: creatine, electrolytes and amino acids then follow around the whey. It is also a demanding market, where buyers compare labels, protein per serving and taste. A new brand wins by being clear about what is in the tub and consistent in how it tastes, batch after batch.
Athletes, daily use
Demanding athletes, cutting phases
Vegans, lactose-intolerant consumers
We detail these differences in whey vs plant protein powder. A starter range can include a whey in two or three flavors, then a plant version.
Most protein brands grow in layers. The first layer is the whey itself, in a few flavors. The second adds a plant protein for dairy-free consumers. The third brings complementary products: creatine for strength, electrolytes for hydration, sometimes a protein in stick packs for gym bags. Planning these layers from the start helps you choose a consistent design system, a shared label structure and a single manufacturer, so that each new product reaches the market faster and looks like it belongs to the same brand.
Protein sells mostly in large sizes. The resealable doypack has become the standard: it is light, cheaper to ship than a rigid tub and gives you a large surface for your design. Tubs remain popular in specialty retail, and single-serve stick packs let you offer samples or multi-flavor discovery sets.
Depending on its composition and presentation, a protein powder can be sold in the EU as a food supplement or as a regular food. The status drives the steps: in France, a food supplement is notified to the DGCCRF before its first sale on the Compl'Alim platform (which replaced Teleicare) and carries the mandatory supplement particulars. In every case, the label follows Regulation (EU) No 1169/2011: ingredient list, allergens (milk for whey), nutrition declaration, net quantity, best-before date.
Protein claims are authorized under Regulation (EU) No 432/2012 subject to content conditions, such as "protein contributes to a growth in muscle mass" or "protein contributes to the maintenance of muscle mass". Our regulatory support team helps you define the status and reviews your label. For the US, labeling follows FDA rules.
A protein brand is built over time: consistent taste and quality from batch to batch is what keeps customers loyal. That is why raw material specifications and release testing are essential, and why we share them with you.
For a protein brand, manufacturing in France brings full traceability, from the raw material certificate of analysis to finished product testing. It reassures clubs, gyms and distributors, who increasingly ask for proof of origin and testing. It also makes it easier to restock your best-selling flavors without waiting for containers, with a single point of contact for quality, compliance and logistics.
Small batches are available on our standard white label formulas: launch a whey in one or two flavors, watch your sales, then add flavors or a plant version. Real sales data tells you which flavors deserve a larger run and which ones to drop, before you commit to large inventories. For a custom recipe, the minimum depends on the development.

Irati Production formulates, blends and packs your whey or plant protein in Saumur.
Choose your protein type, flavors and format, then a white label or custom formula with a manufacturer. The manufacturer produces and reviews the label; your brand places the product on the market and sells it.
Whey remains the most requested by athletes; plant protein targets vegan consumers and those avoiding dairy. Many brands offer both.
It depends on its composition and presentation: it can be a food supplement or a regular food. The status determines notification and mandatory label particulars.
Only authorized claims, subject to content conditions, such as "protein contributes to a growth in muscle mass".
The resealable doypack is the reference format; tubs and single-serve stick packs complete the range.
The information in this article is general. Each formula undergoes a technical and regulatory feasibility study.
