New chart on stability of vitamin K2 as vitaMK7®

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.
