New chart on stability of vitamin K2 as vitaMK7®

Thursday, July 26, 2018 by Gnosis by Lesaffre

Gnosis is pleased to share with its partners and clients the results taken from the "Stability Study Project", which was carried out on the vitaMK7® ingredient, when it is conducted with different mineral salts. This new data is relevant for a 12 month period, when vitaMK7® is formulated with Calcium Citrate, Calcium Carbonate and Arginine.

Thanks to the clean profile, vitaMK7® shows excellent stability data, three years at room temperature, and remarkable assay recovery to short time light exposure (48h) at approximately 93% - which is where the issue of stability comes in.

Also in formulation, vitaMK7® shows an optimal stability with different calcium salts, without any coating. This 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 the K2 label claim. A pure and stable MK7 ingredient like vitaMK7® minimises the cross-reactions with other ingredients/excipients included in a formulation for the whole shelf-life of the product, and offer extended warranty of stability.
