New Market Study Reveals K2 Stability Problem

Overview

Half of all vitamin K2 products tested in a 2016 Market Study missed label claim by 50% or more. One-in-five demonstrated no measurable K2 content (zero). These products failed in both multi-ingredient formulations and K2-only formulations. Only one category of K2 product performed at 100% label claim.

Vitamin K2 is a fat-soluble vitamin, and like vitamins A, D and E it can degrade in certain formulations. Unprotected K2 MK-7 does not tolerate calcium or magnesium. This is bad news for many bone, heart and multivitamin products. What’s behind these poor study results? Is there a solution?
