Vitamin K2 Bulk Powder

Vitamin K2 Bulk Powder - Premium MK-7 Manufacturing Ingredient

Xi'an Linnas Biotech Co., Ltd. supplies pharmaceutical-grade Vitamin K2 Bulk Powder in MK-7 (Menaquinone-7) form, engineered for manufacturers requiring consistent potency and regulatory compliance. Our product delivers ≥1% concentration with all-trans isomer purity exceeding 95%, addressing the industry challenge of calcium metabolism regulation in bone and cardiovascular formulations. Manufactured under ISO 9001, HACCP, Halal, and Kosher certifications, our powder maintains stability in alkaline mineral blends through advanced processing. Available in 1-10kg foil bags or 20-25kg drums, we guarantee delivery within 3 days post-payment. This light yellow powder solves formulation instability issues while meeting USP and EP quality standards for global nutraceutical and functional food applications.

Technical Specifications

Why Manufacturers Choose Our Vitamin K2 Powder

The nutraceutical industry faces persistent challenges with calcium supplementation causing arterial calcification rather than bone strengthening. Our powder directly activates Osteocalcin and Matrix Gla Protein, redirecting calcium to skeletal tissue.

Unlike standard K2 materials that degrade in multi-mineral formulas, our product employs protective processing compatible with calcium carbonate and magnesium oxide. This solves the critical pain point of maintaining label claims throughout product shelf life.

Your formulation benefits from our carrier matrix optimization. We use maltodextrin-based dispersion to ensure homogeneous blending at low inclusion rates, eliminating the hot spots and underdosing common in powder manufacturing.

Production Advantages

Our Xi'an facility operates under Good Manufacturing Practice protocols with automated production lines and inline quality monitoring. Every batch undergoes HPLC testing to verify trans-isomer content and exclude inactive cis-isomers.

We maintain strict control over light exposure and oxygen levels during processing. This prevents photodegradation that typically reduces potency by 15-30% in unprotected bulk powders.

The manufacturing environment adheres to multiple international standards. ISO 9001 ensures process consistency, while Halal and Kosher certifications expand your market access across Middle Eastern and specialty consumer segments.

Application Guidance

Dietary Supplements: Ideal for bone health and cardiovascular support formulas at 45-180 mcg per serving. Compatible with tablets, capsules, and powder blends when using appropriate excipients.

Functional Foods: Suitable for fortification of dairy alternatives, nutrition bars, and beverage powders. Oil-soluble nature requires emulsification systems in aqueous applications.

Pharmaceutical Products: Meets API-grade requirements for prescription osteoporosis therapies. Stability data available to support drug master file submissions.

Quality Assurance Protocol

Each Vitamin K2 Bulk Powder lot includes Certificate of Analysis documenting:

• HPLC chromatogram showing trans/cis ratio
• Microbial limits (TPC, yeast/mold, pathogens)
• Heavy metal screening (Pb, As, Cd, Hg)
• Residual solvent analysis

We provide retention samples for 36 months post-manufacture. Accelerated stability studies demonstrate <5% potency loss under ICH 40°C/75% RH conditions over 6 months.

Third-party testing through SGS or Eurofins available upon request. Our traceability system tracks raw materials to final packaging for complete supply chain transparency.

Custom Manufacturing Services

Linnas offers OEM/ODM solutions beyond raw material supply. Our technical team assists with:

• Dosage optimization based on target health claims
• Excipient selection to enhance bioavailability
• Stability testing in your specific formulation matrix
• Regulatory documentation for FDA, EFSA, or TGA submissions

We customize concentration levels from 0.1% to 10% depending on your manufacturing equipment and final product format. Microencapsulated beadlet versions available for challenging formulations.

Frequently Asked Questions

Q: What differentiates natural fermentation from synthetic sources?

A: Both methods produce identical all-trans MK-7 molecules. Fermentation uses Bacillus subtilis natto for clean-label marketing, while synthetic offers cost advantages. Biological activity remains equivalent when isomer purity meets specifications.

Q: How do you prevent degradation in mineral blends?

A: Standard powder degrades rapidly in alkaline environments. Our processing includes protective coating technology that shields the K2 molecule from direct contact with calcium and magnesium salts.

Q: Can you verify isomer content?

A: Yes. We provide HPLC chromatograms clearly separating trans and cis peaks. Total K2 assay alone is insufficient—always request specific trans-isomer quantification from suppliers.

Q: Is this water-soluble?

A: MK-7 is naturally oil-soluble. For aqueous applications, request our cold-water dispersible (CWD) version using specialized emulsification technology.

Q: What is typical shelf life?

A: 24 months when stored below 25°C in sealed containers away from light. Microencapsulated formats may extend retention to 36 months under proper conditions.
