Choosing a supplement filling and packaging company starts with understanding your product. Protein powders, vitamin capsules, liquid supplements, tablets and gummies require different equipment and processes. A company experienced in filling capsules may not be equipped to pack powders into large retail containers, just as a powder specialist may not offer blister packaging.

Meanwhile, the supplement market continues to develop. According to a 2026 study published by AESGP, 55% of surveyed consumers purchase food supplements, while participating manufacturers expect further sales growth. New formulations and formats create opportunities for brands.

“The supplement market is growing, and we can see it in the enquiries we receive. Both established brands and businesses preparing new products are exploring electrolyte mixes, creatine, protein powders and other functional blends. Their questions often go beyond ingredients to portion sizes, packaging formats and production volumes,” says Bartosz Grajewski, Director at TRANSPAK, a specialist stick pack and sachet co-packer.

For brands seeking an external filling or manufacturing partner, these five European companies offer different specialisations.

How to Choose the Right Supplement Filling and Packaging Partner

Before approaching a supplier, prepare a brief describing your formulation, product form, packaging, quantities and intended sales markets.

Consider five practical questions:

  • Product compatibility: Does the company regularly handle your type of supplement?
  • Packaging options: Can it provide the required format, portion size and materials?
  • Production scope: Do you need filling alone, or also blending, formulation and sourcing?
  • Quality requirements: Which certifications, testing procedures and traceability systems apply?
  • Commercial flexibility: What are the minimum order quantities, lead times and testing costs?

The right supplier is not necessarily the company offering the widest range of services. It is the one whose equipment, experience and production model best match your supplement.
