Capsule Manufacturing

In addition to our core powder-based manufacturing expertise, Protein Partners offers capsule manufacturing services — enabling brands to deliver supplement formulas in one of the market’s most trusted and versatile product formats.

Whether you are adding a capsule SKU to an existing powder range, or launching your first supplement product in encapsulated form, our team will guide you through the process from formulation to finished pack.

Capsule Format

Hard Shell Capsules (HPMC)

Hard shell two-piece capsules are the most widely used format in the supplement industry, offering excellent stability, precise dosing and strong consumer familiarity.

We offer HPMC (hydroxypropyl methylcellulose) capsules. HPMC capsules are plant-derived, suitable for vegetarian, vegan and halal-certified.

Vegan & Vegetarian Options

The demand for vegan-certified supplement formats continues to grow significantly. Our HPMC capsule offering provides a fully plant-based solution that does not compromise on performance, stability or shelf life making it the preferred choice for brands targeting health-conscious, ethical or lifestyle-focused consumers.

What We Can Encapsulate

Our encapsulation capability covers a broad range of supplement ingredients and blended formulas, including:

  • Vitamins and minerals
  • Botanical extracts and herbal ingredients
  • Amino acids (single and blended)
  • Probiotics and digestive enzymes
  • Collagen peptides
  • Sports performance ingredients (creatine, beta-alanine, caffeine and more)
  • Custom multi-ingredient blends

Our NPD team can advise on ingredient compatibility, optimal fill weights, and capsule size selection to ensure the best possible product outcome.

Quality & Compliance

All capsule manufacturing at Protein Partners is carried out under the same rigorous quality management systems that govern our wider production operations. This means:

  • Certified manufacturing under GMP for food supplements
  • Full batch traceability and documentation
  • Weight verification and fill accuracy checks
  • Pre-release quality sign-off on every batch
  • Compliance guidance for UK and international markets

For brands seeking third-party certification such as Informed Sport or Informed Manufacturer status, our team can advise on the testing and documentation requirements involved.

Capsule Packaging Options

Finished capsules can be packaged in a variety of formats to suit your brand and retail requirements:

  • HDPE and PET bottles (various sizes)
  • Pouches and foil sachets
  • Bulk supply for brand-side repacking

All packaging operations include batch coding, lid heat sealing and full compliance labelling support.
