Dietary supplement contract manufacturing — process and costs step by step
Outsourcing production to an external manufacturer lets you bring a supplement to market without your own production line. We explain how the whole collaboration works — from idea to delivery — and what really determines a batch's price.
What contract manufacturing is
Contract manufacturing is a model in which the brand owner outsources the entire product manufacturing to an external producer. The producer is responsible for the formula, sourcing and verification of raw materials, production, packaging and regulatory compliance, while the brand focuses on sales and marketing. The finished product reaches the market under the client's brand — hence the popular term private label.
This lets you launch your own supplement line without investing in a plant, machinery, a laboratory and a team of technologists. It works both for start-ups testing their first product and for large brands expanding their portfolio.
The process in six stages
At Onesano, cooperation has a predictable structure. Each stage ends with a decision point where the client approves the next steps.
1. Formula development
The starting point is the product goal and target audience. The R&D department designs a composition matched to the requirements and market trends, or works on a formula supplied by the client. At this stage, dosage, form and labeling assumptions are also set.
2. Implementation and testing
The formula goes to the laboratory. Prototypes are produced, quality tests and stability verification are carried out. This is when technological problems are caught before serial production begins.
3. Production
Manufacturing in the chosen form — tablets, capsules, liquids, powders or gummies. Production is carried out in accordance with GMP, HACCP, FSSC 22000, FAMI-QS and V-label standards, maintaining line cleanliness (important with allergens).
4. Packaging
The product is packed in the selected packaging: PET bottles, glass, blisters, stick-pack sachets or doypack pouches. The choice of packaging affects both cost and product positioning (e.g. glass in the premium segment).
5. Labeling and GIS registration
The label design is prepared in accordance with regulations, and the product is notified with the Chief Sanitary Inspectorate. Onesano provides full regulatory support — from documentation to labeling assessment. We cover the details in our guide to GIS registration.
6. Shipping
The finished product is delivered to the specified location. At this stage the brand can start selling.
What affects the cost of contract manufacturing
There is no single “price per supplement” — the unit cost comes from several variables. The table below organizes the most important ones.
| Factor | How it affects the price |
|---|---|
| Formula and raw materials | Standard ingredients are cheaper; premium extracts, patented ingredients and Novel Food raise the cost. |
| Product form | Gummies and softgels are usually more expensive to make than tablets or powders. |
| Batch size (MOQ) | A larger run lowers the unit cost — fixed costs are spread over more units. |
| Packaging | Glass and premium solutions cost more than standard PET. |
| Regulatory support | Formula development from scratch, testing and GIS registration are an additional but one-off outlay. |
Practical takeaway: unit cost drops most sharply with order scale, but the first trial batch is deliberately more expensive per unit — an investment in testing the product on the market. We write about choosing the first-run size in our article on MOQ in contract manufacturing.
How long it takes
At Onesano, production starts from 6 weeks after project approval. The actual time depends on the formula's complexity, raw-material availability, the form and packaging, and whether GIS registration is needed. The stages before production itself — refining the composition and testing — usually take the most time.
Frequently asked questions
How much does contract manufacturing of a supplement cost?
The cost depends on the formula and raw materials, product form, batch size (MOQ), packaging and the scope of regulatory support. A larger run lowers the unit price; an exact quote is prepared once the composition and volume are defined.

Do I need to have a ready formula?
No. We can develop a formula from scratch in our R&D department, work on a formula supplied by the client, or manufacture from client-supplied raw materials.
