Product Overview
Our all-trans Vitamin K2 (menaquinone MK-4/MK-7) is premium fat-soluble vitamin raw material manufactured in dedicated cGMP workshops for global food, supplement and pharmaceutical manufacturers.
We apply two mature production workflows: low-temperature anaerobic fermentation for high-bioavailability MK-7 and asymmetric catalytic synthesis for stable MK-4. UV-filtered production zones and low-temp vacuum extraction stop light and heat-triggered molecular degradation. Industrial high-separation chromatography removes inactive cis-isomers to guarantee ≥96% active ingredient content matching USP & EP standards.
Full-stage quality control covers substrate inspection, in-process monitoring, heavy metal, solvent, PAH and microbial testing via HPLC, ICP-MS and GC-MS. Multi-phase carbon filtration removes fermentation odors to deliver neutral-taste powder for unflavored finished goods.
Two delivery forms are offered: oil-soluble yellow crystal powder for softgels and oil fortification; mineral-stabilized microencapsulated powder with anti-alkaline coating, compatible with high-calcium liquid formulas to avoid decomposition and container bulging. Uniform particle size ensures smooth mixing and tableting during mass production.
This K2 activates osteocalcin to boost bone mineral absorption, widely paired with Vitamin D3 for bone health formulas. Complete regulatory documents support EU, US and Southeast Asia customs clearance and local brand registration.

FAQ
Q1: What's the shelf life of your bulk Vitamin K2 crystal powder and microencapsulated powder respectively?
A: Sealed cold storage (<20℃, light-proof) high-purity crystal powder shelf life reaches 24 months; microencapsulated powder maintains stable activity for 18 months under the same storage environment, with desiccant added inside packaging to prevent agglomeration.
Q2: Can your Vitamin K2 be used for EU Novel Food registered finished products and US GRAS supplement lines?
A: Yes. We supply complete EU Novel Food technical dossier and FDA GRAS supporting files for every batch, all test indicators fully align with EU and US food safety standards, directly applicable for local brand registration.
Q3: How to solve the agglomeration problem of microencapsulated K2 powder during sea freight long transit?
A: All microencapsulated bulk goods adopt desiccant-integrated humidity sealed canisters + insulated cold-chain pallet packaging; nitrogen filling before sealing removes internal moisture and oxygen, effectively preventing powder caking during long-distance marine transportation.
Q4: What test reports will be provided along with each shipment order?
A: Each shipment attaches full COA including HPLC assay, heavy metal ICP-MS test, residual solvent GC-MS, PAH detection and microbial limit report; additional factory cGMP audit document, USP EP compliance certificate can be supplied on request.
Q5: Is your Vitamin K2 compatible with calcium carbonate liquid formulas without container bulging?
A: Our mineral-stabilized microencapsulated grade adopts anti-alkaline coating film, which isolates K2 from alkaline calcium matrix, avoiding molecular degradation and gas generation to eliminate barrel bulging risk in high-calcium liquid products.
Q6: Do you offer free samples for formulation testing? What is the sample delivery rule?
A: We support free 10–50g lab samples for client formula trial; courier freight is collected on recipient's side. Formal bulk order clients can apply for fully covered sample shipping cost after cooperation confirmation.
Q7: What is the difference between your fermentation MK-7 and synthetic MK-4 in formulation application scenarios?
A: Fermented MK-7 features higher bioavailability, ideal for bone health premium supplements and high-end functional food; synthetic MK-4 owns better thermal stability, more suitable for high-temperature tableting and oil fortification mass production. We support mixed ratio customization of two isomers.
Q8: What cold chain logistics protection do you provide for air freight and sea freight bulk shipments?
A: Air cargo uses passive cooling thermal insulation pallets to buffer high tarmac temperature; sea bulk orders adopt constant-temperature container transportation, all packaging uses UV-opaque amber aluminum barrier to block light-induced ingredient degradation during whole transit.
