Since the first production launched almost 20 years ago, we rigorously control and measure the level of purity of VitaMK7® at every step of the manufacturing process in our cGMP plant. We use the most advanced detection techniques (HPLC) to characterize the purity of our vitamin K2.

Today, we decided to share with you the purity profile of all the production batches produced over the last 30 months.

We are the first and only supplier of vitamin K2 which discloses such a level of information. And we both are proud to do it, as we believe that it demonstrates both the quality of our products and our desire to be a transparent organization.

”To help brands and consumers understand how the purity of vitamin K2 should be measured, we decided to prepare a dedicated leaflet including the definition of the two criteria to be considered and the actual results of purity profile of VitaMK7®” said Xavier Berger, Mobility and Joint Health Market Manager at Gnosis by Lesaffre.
