Vitamin K2 Capsule Manufacturer for Brand Owners

Our Guangdong facility runs automatic capsule filling lines with an output of 120,000 capsules per hour. For vitamin K2, we use low-oxygen encapsulation and inline weight checks to keep fill weight within ±3%. The cleanroom operates at ISO 8 for general filling and ISO 7 for sensitive steps. We handle both powder-in-capsule and pellet-filled formats. Tooling changes for different capsule sizes take under 4 hours. This means a 50,000-unit order can move from approved sample to packed bottles in 20–35 working days.

We bottle in HDPE, PET or glass, with induction seals and child-resistant caps where required. Labelling supports FDA and EU compliance fields. Cartoning and shrink-wrapping are done in-house. For buyers sourcing from our /capsule-manufacturer parent service, vitamin K2 fits the same MOQ and lead-time structure as other fat-soluble vitamins. We also run combination fills with vitamin D3 or calcium, provided the actives are compatible and stability data supports the blend.

Vitamin K2 is available as MK-7 (menaquinone-7) and MK-4 (menaquinone-4). MK-7 is typically produced by fermentation and has a longer half-life; common dosages are 45 mcg, 90 mcg, 100 mcg and 200 mcg. MK-4 is synthetic and often dosed at 45 mcg or higher, though some markets prefer 15 mg. We source MK-7 from EU and Asian suppliers with documented all-trans content above 95%. Each lot arrives with a certificate of analysis and is retested in-house for assay, heavy metals and microbial limits.

Because MK-7 is sensitive to oxidation, we recommend HPMC shells for vegan claims and add natural antioxidants such as mixed tocopherols where the formula allows. We can dilute the active with microcrystalline cellulose or rice flour to reach a target fill weight. For oil-based fills, we use a liquid filling line that handles medium-chain triglycerides. If you need organic certification, we can source or EU-organic K2 and run the batch under organic handling rules.

Every vitamin K2 batch is tested for identity, potency, heavy metals, microbial contamination and residual solvents. We hold GMP, ISO 22000 and HACCP certifications. Halal certificates are available for gelatin-free and gelatin-based shells respectively. Our facility is FDA-registered for dietary supplements. We maintain full traceability from raw material lot to finished bottle. Retain samples are kept for 24 months. Stability studies follow ICH accelerated conditions at 40°C/75% RH for 6 months, with real-time data available for 12 and 24 months.

Documentation for each shipment includes a certificate of analysis, certificate of origin, allergen statement, GMO statement and a packaging list. We support third-party testing through SGS, Eurofins or Intertek at the buyer's request. For Middle East buyers, we provide halal certificates from recognised bodies. For EU buyers, we can supply documentation for novel food or health claim dossiers where applicable. Our QA team responds to technical queries within 1 working day. Annual audits are welcome with 2 weeks' notice.

We offer primary packaging in HDPE bottles (30, 60, 90, 120, 180, and 240 counts), blister packs (10, 14, 21, 28, and 30 capsules per blister), stick packs for single-dose formats, and sachets for powder blends. Bottles can include induction seals, desiccant sachets, and child-resistant closures. Blisters use PVC/PVDC or alu-alu for moisture protection. For stick packs, fill weights range from 1 g to 5 g, suitable for combination products with vitamin D3 or magnesium.

Labels are produced to your artwork and must include the FDA dietary-supplement panel: statement of identity, net quantity, supplement facts, other ingredients, directions, warnings, and manufacturer/distributor details. We also support EU labelling with nutrition declaration, allergens, and country of origin. Lot and expiry coding is applied by inkjet or laser, with formats such as LOT YYMMDD and EXP YYMM. Cartons are printed with batch, quantity, and handling symbols. Pallet specifications follow standard 1200×1000 mm or 1200×800 mm footprints, stretch-wrapped and labelled for export.

For Amazon FNSKU and retail compliance, we can apply FNSKU labels, poly-bag units, and apply suffocation warnings where required. We do not provide Amazon account services, but our packaging team is familiar with FBA prep requirements and can prepare cartons with the correct box dimensions and weight limits. Retail-ready packaging such as shelf-ready trays or display cartons is available on request, subject to minimum order quantities.

The sample timeline starts with a brief and formulation confirmation. We provide 7–10 working days for lab-scale samples, including capsule shell and fill weight trials. If a new blend or custom dosage is required, add 3–5 working days for formulation development. Samples are shipped by courier with a proforma invoice and COA. Sample costs are credited against the first mass production order for quantities above 1,000 units.

Mass production lead time is 20–35 working days after sample approval and receipt of deposit. This covers raw material procurement, encapsulation, packaging, and QC release. Peak seasons (Q3–Q4) may extend lead times by 5–7 working days. For repeat orders with existing artwork and approved materials, lead time can be reduced to 15–25 working days. We provide a production schedule at order confirmation and weekly updates.

Shipping options include air freight (5–10 days door-to-door) and sea freight (25–40 days port-to-port). We quote EXW, FOB Shenzhen/Hong Kong, and DDP for selected destinations. Documents provided with each shipment include COA, MSDS, free-sale certificate, and phytosanitary certificate where applicable (for gelatin capsules of animal origin). Commercial invoice, packing list, and bill of lading are issued per Incoterm. For DDP, we handle customs clearance and delivery to your warehouse.
