Private Label Capsule Manufacturers and Contract Capsule Producers

Home > Supplements > Capsule

Capsule manufacturing covers two distinct production types with fundamentally different equipment and expertise requirements: hard-shell capsule filling and softgel encapsulation. Choosing the wrong manufacturer type for your product format is one of the most common early mistakes in supplement brand development. This page lists capsule manufacturers producing hard-shell, softgel, vegetarian, and delayed-release formats. Use the filters to compare by capsule type, certifications, and location.

Hard-Shell vs. Softgel Capsules: Choosing the Right Manufacturer

Hard-shell and softgel capsules require completely different manufacturing processes and equipment. Confirming your manufacturer specializes in your required format before development begins prevents costly pivots later.

Hard-Shell Capsule Manufacturing

Hard-shell capsules are filled with dry blends, granulates, or pellets. The primary quality considerations are capsule shell material, fill weight consistency, and sealing integrity. Gelatin capsules are the industry standard. HPMC vegetarian capsules are required for vegan, vegetarian, and Halal positioning but have different moisture sensitivity characteristics affecting ingredient compatibility and shelf life. Confirm your manufacturer has specific experience with your required shell material before committing to development.

Softgel Manufacturing

Softgels are appropriate for oil-based ingredients, fat-soluble vitamins, omega-3 fatty acids, and ingredients that benefit from lipid delivery systems for absorption. Softgel manufacturing requires specialized rotary die equipment distinct from hard-shell capsule filling lines. Not all supplement manufacturers produce softgels. Fish oil softgels require incoming oil testing for TOTOX value to confirm oxidation status before use. Confirm in-house softgel capability upfront for any oil-based formula.

Delayed-Release and Enteric-Coated Capsules

Delayed-release and enteric-coated capsules are used for ingredients sensitive to stomach acid or intended to release in the small intestine. Probiotics, certain enzymes, and some botanical extracts benefit from this technology. Confirm your manufacturer has demonstrated delayed-release capability and can provide dissolution testing data showing the coating performs as intended under simulated gastric conditions.

Key Certifications for Capsule Supplement Brands

Certification requirements differ depending on whether your product is a dietary supplement or an OTC drug, and on your target retail channel.

NSF Certified and USP Verified are the primary certifications for supplement capsules. For OTC drug applications, manufacturers must hold FDA drug facility registration and comply with 21 CFR Parts 210 and 211. Supplement capsule manufacturers are not automatically qualified for OTC drug production. Informed Sport and NSF Certified for Sport are relevant for capsules targeting the athlete market.

MOQs for Private Label Capsule Manufacturing

MOQs vary significantly between hard-shell and softgel formats due to the difference in equipment setup costs.

Hard-shell capsule production typically starts at 5,000 to 25,000 units per SKU at manufacturers serving emerging brands. Softgel MOQs are generally higher, starting at 25,000 to 100,000 units due to equipment setup costs. Delayed-release and specialty coatings add per-unit cost and may increase effective MOQs at some facilities.
