Encapsulation MK-7

Encapsulated MK-7 is menaquinone-7, a form of vitamin K2, supplied by Nustras as a free-flowing powder in which the active is enclosed in a protective matrix for use in dry supplement and premix formulations. Menaquinone-7 is a fat-soluble naphthoquinone with a long unsaturated side chain; the encapsulated format protects it from light, moisture and alkaline conditions.

It is formulated into vitamin K2 and multivitamin supplements in capsule, tablet and powder form, vitamin premixes, fortified foods and powdered beverages, where a dry, dispersible vitamin K2 ingredient is required.

The material is a powder, typically white to pale yellow; the active menaquinone-7 has CAS number 2124-57-4, molecular formula C46H64O2 and molecular weight 649.0. Menaquinone-7 content is confirmed by HPLC, identity by its chromatographic retention and spectrum, and the material is standardised to specification. Heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies encapsulated MK-7 in bulk commercial quantities, in sealed light-protected packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Vitamin K2 as menaquinone-7 is an accepted supplement ingredient in major markets; buyers confirm the vitamin K2 contribution, grade and permitted level for their application.
