VITAMIN K2 MK7
POWDER 1.3% (MENAQUINONE-7)
Vitamin K2 MK7 (Menaquinone-7, CAS 2124-57-4) is a highly bio-available fat-soluble vitamin produced through the natural fermentation of Bacillus subtilis natto. As a standardized Food Grade Raw Material, this 1.3% concentration powder is engineered for precise integration into functional food matrices. It is characterized by its superior half-life in the bloodstream compared to Vitamin K1 or MK4, making it a premium Raw Powder for nutrient fortification. This Raw Ingredient is typically stabilized on a food-grade carrier (such as Maltodextrin or Microcrystalline Cellulose) to ensure uniform distribution and stability during processing.
TECHNICAL SPECIFICATIONS
CORE HIGHLIGHTS
1. Natural Fermentation Origin
Derived from traditional natto fermentation processes, ensuring a clean-label profile for premium food applications.
2. Superior Bio-availability
The MK7 form (Menaquinone-7) provides a significantly longer half-life (up to 72 hours) in the human body compared to synthetic Vitamin K1 or MK4.
3. High All-Trans Configuration
Our 1.3% powder is optimized for maximum biological activity with an all-trans content exceeding 98%.
4. Enhanced Stability & Flowability
Utilizing advanced micro-encapsulation or specialized carriers to maintain potency against light, heat, and oxygen during the manufacturing of finished food products.
Supply Chain Compliance
We strictly control every step of the process. Our facility is audited annually to maintain global quality standards.
FUNCTIONAL ROLES
1. Calcium Metabolism Regulation
Acts as a cofactor for the activation of Matrix Gla Protein (MGP), which prevents calcium deposition in vascular tissues.
2. Osteocalcin Carboxylation
Facilitates the binding of calcium to the bone matrix by activating the protein osteocalcin, supporting bone structural integrity.
3. Synergistic Nutrient Support
Enhances the efficacy of Vitamin D3 and Calcium in fortified food formulations by ensuring proper calcium direction.
4. Cardiovascular Support
Contributes to the maintenance of arterial elasticity through the regulation of soft tissue calcification pathways.
INDUSTRY APPLICATIONS
1. Functional Food & Beverages
Integration into meal replacement powders, energy bars, and high-performance health beverages.
2. Dairy Fortification
Enrichment of milk powders, yogurt, and cheese products with stable, bio-available Vitamin K2.
3. Nutrient Premixes
A primary component for custom vitamin-mineral blends targeted at structural and metabolic health.
4. Specialized Nutrition
Used in medical-grade food formulations requiring high-precision nutrient densities.

TECHNICAL FAQ
Q1: What is the difference between MK4 and MK7 in B2B applications?
A1: MK7 (Menaquinone-7) is much more stable and has a significantly longer half-life in the bloodstream (approx. 72 hours vs. 1-2 hours for MK4), allowing for lower dosage levels while achieving higher tissue saturation.
Q2: Is the 1.3% powder sensitive to light and heat?
A2: While pure Vitamin K2 is sensitive, our 1.3% standardized powder is stabilized via carrier technology. However, we still recommend storage in light-proof containers at temperatures below 20°C to ensure maximum shelf-life.
Q3: Does the product contain any soy allergens?
A3: Although derived from natto (fermented soy), the purification process removes most soy proteins. We provide allergen-free certificates upon request depending on the specific purification batch.
