1. Getting Started — With No Prior Experience

The first questions people ask before deciding whether to move forward.

The process involves three main stages: choosing a formula (a ready-made one from a library or custom development from scratch), manufacturing at a certified (GMP) factory with your own branding on the packaging and label, and regulatory compliance (notification to EOF before market placement in Greece). At Swiss Formula, these three stages are covered as an integrated service, with a library of 1,600+ formulas so you can get started without waiting for development from scratch. See all the steps in detail in our free guide.
Private label means a company develops or offers a formula, manufactures it at a certified factory, and the finished product carries exclusively your own brand and packaging. It differs from white label in that it usually allows the formula to be adapted to your own specifications, while white label offers an already existing product with only the label changed.
The cost mainly depends on three factors: whether you use an existing formula or custom formulation from scratch (significantly more expensive and time-consuming), the minimum production quantity per batch, and the level of packaging/label design. Ready-made formulas with standard packaging have a significantly lower initial starting cost.
Yes. Every dietary supplement must be notified to EOF before it is placed on the Greek market, in accordance with Directive 2002/46/EC. The process requires a complete dossier covering the composition, label, and health claims in compliance with Regulation (EC) 1924/2006. You don't need your own factory operating license — that concerns the manufacturer; you need the product notification/declaration.
The main steps: 1) define the target market and purpose, 2) choose a formula, 3) approve the composition and a test batch, 4) design the label/packaging, 5) notify EOF, 6) manufacture the final batch, 7) place the product on the market. The timeline varies significantly depending on whether the formula is already ready.
With white label, the product is already fully formulated and the only change is the label — lower cost, less differentiation. With private label, the formula can be adapted to your own specifications, offering greater flexibility but usually at a higher cost and longer timeline.
Yes — this is the core of the private label/contract manufacturing model. You partner with a certified (GMP) manufacturer that produces the product according to your specifications, while you manage the brand, marketing, and distribution. The majority of small and medium-sized supplement brands in Europe operate exactly with this model.
With a ready-made formula from a library, the process can be completed in a few weeks to 2-3 months. With custom formulation from scratch, the time is significantly longer, since it requires more strategic thinking, stability testing, and regulatory evaluation before the final batch is manufactured.
For an initial order with a ready-made formula, a general estimate is about 8-12 weeks from order placement to delivery, covering label design, EOF notification, manufacturing, and shipping. Repeat orders are usually faster, since the label and notification are already approved.

2. Finding a Manufacturer / Partner

How to find and evaluate who will manufacture your product.

There are many private label/contract manufacturing companies in Greece and Europe, with significant differences in formula range, minimum order quantity, certifications, and support with regulatory matters. It's worth comparing based on specific criteria rather than price alone. Swiss Formula operates as a brand developer with a network of certified European factories and a library of 1,600+ formulas — see all the B2B services we offer.
Yes, several manufacturers offer smaller minimum quantities especially for ready-made formulas in standard packaging, unlike custom formulation which usually requires larger batches. As an example, some private label providers allow an initial order from 500 units, with packaging options from 30 to 120 units per box. When comparing suppliers, ask for a specific MOQ number per formula and packaging size.
Companies with their own R&D department, or access to laboratories whose exclusive work is formula research and development, can develop a custom composition based on your own specifications. It requires more time and cost than a ready-made formula. It's a good idea to ask to see previous formula development examples before committing. You can see sample ready-made formulas at the Formula Finder.
It means the brand developer already has ready, tested compositions available for production, without development from scratch. This significantly reduces startup time and R&D cost. A single factory usually has 5 to 30 at most ready-made formulas to choose from, since it focuses on manufacturing rather than developing a broader portfolio. If you work with a brand development company like Swiss Formula, which represents more than one factory, the available portfolio becomes significantly larger: for example, more than 1,600 ready-made formulas in total, with a portion of these updated every 30 days. The update frequency shows how actively the library is maintained — not just its size.
Brand development companies that operate as a single point of contact (one-stop-shop) usually cover formula, manufacturing, label/packaging design, and regulatory support in one package, instead of you having to coordinate a factory, a graphic designer, and an EOF consultant separately. This significantly reduces the risk of errors between stages.
GMP (Good Manufacturing Practice) is an internationally recognized standard that ensures controlled hygiene procedures, raw material traceability, and quality control at every stage of manufacturing. Before choosing a manufacturer, ask to see the GMP certificate of the factory that will actually manufacture your product — not just of the company that's recommending it to you, since these aren't always the same entity.
A Certificate of Analysis is the document that certifies the composition, purity, and quality of a specific batch of raw material or finished product, based on laboratory testing (microbiology, heavy metals, active ingredients, etc.). A serious private label company provides a CoA for every production batch, so you have full documentation of your product's quality at any time.
Yes. In private label partnerships with an exclusive formula, the client retains exclusive ownership of the composition and label, while the manufacturer commits not to make it available to other clients. This differs from choosing a ready-made formula from a shared library, where the same composition can be used by other brands with a different label. It's worth clarifying from the start which model you're choosing, as it affects your product's differentiation in the market.

3. Comparison & Selection Criteria

What to look at before committing to a partner.

The main criteria: GMP certification of the actual factory, range and quality of available formulas, minimum order quantity per product, support with regulatory compliance (EOF/EFSA), transparency about who actually manufactures, and delivery time. Always ask to see a sample of previous collaboration or certificates before committing.
Many private label companies offer support in preparing the EOF notification dossier (composition, label, health claims), although the notification itself is submitted under the name of the company placing the product on the market. Clarify from the start who is responsible for which part of the process, to avoid gaps in liability.
It varies significantly by manufacturer and formula type: ready-made formulas in standard packaging often have a lower MOQ, while custom formulation or specialized packaging require larger batches. Always ask for a specific number per product — general references to "low MOQ" without a number aren't enough for comparison.
The cost of custom formulation depends on the complexity of the composition, the number and cost of raw materials, stability testing, and any documentation needed for health claims. It is significantly more expensive and time-consuming than a ready-made formula — which is why many new brands start with a ready-made formula and move to custom development in a later phase.
Demand is particularly high in wellness categories such as vitamins (mainly D and C), probiotics, magnesium, omega-3, and collagen, as well as functional supplements that support the immune system, joints, and sleep. Products that address an immediate, noticeable symptom (e.g. pain, insomnia, bloating) tend to have a stronger and more immediate commercial response compared to purely preventive products, which require more consumer education. Because this data changes constantly, the core role of a good private label supplier isn't just manufacturing — it's personalized consulting and access to market data and forecasts, so that category selection is based on current information rather than assumptions.

4. Practical Matters & Regulations

What you need to know about labeling, health claims, and notification.

The label must include, among other things: product name, complete list of ingredients, composition per daily dose, recommended dosage, a warning not to exceed the recommended dose, a statement that the supplement is not a substitute for a balanced diet, the responsible party's details, batch number, and expiry date. Unauthorized health claims are among the most common reasons for EOF to reject a notification.
Only health claims that are approved and registered in the EFSA register under Regulation (EC) 1924/2006 are permitted, and they must correspond to the dosage approved for that specific claim. Generalized or exaggerated claims (e.g. therapeutic properties) are not permitted and are a common reason for rejection or penalties.
The company that places the product on the market under its own brand approves the final label and health claims, while the manufacturer/brand developer usually handles the EOF notification and manufacturing compliance. This clear division of roles is defined in a written partnership agreement, so both parties know in advance what each covers — this is something a serious private label company will explain clearly from the first point of contact. See who we are and how we work.
In rare cases, a competent authority may request a minor modification to the labeling or a claim after a product has launched. A serious private label contract provides for a clear, organized process for this scenario in advance, so it can be handled quickly and without complications for your brand. Knowing from the start how this process works is part of proper preparation before you begin.
