New chart on stability of vitamin K2 as vitaMK7®
June 11th, 2018
Thanks to the clean profile, vitaMK7® shows excellent stability data – 4 years at room temperature - and remarkable assay recovery to short time light exposure (48h) of approximately 93%, the real stability issue.
|Also in formulation, vitaMK7® shows an optimal stability with different calcium salts without any coating which increases non-natural substances. In the entire analytical tests, the Official USP assay method for Menaquinone-7 was applied.|
Generally, impurities are characteristics of both synthetic-derived MK7 and poor production method of fermentation-derived MK7. The use of solvents in the production process can also degrade the product and produce further impurities.
As such, with a high level of impurities, K2-plus-mineral products are likely to miss K2 label claim.
