The primary purity of an active ingredient affects its stability, because it minimises the cross-reactions with other substances included in the material offered, even in very small quantities.
Thanks to its very high purity profile with more than 99% of all-trans MK7 assay, and no unknown impurities, VitaMK7 offers extended stability in the global market, with four years at room temperature granted in the product specification, and supported by the routinely stability tests carried out on the batches produced.
As a rule, synthetic vitamins K2 show high levels of impurities and - as a consequence - the lowest purity profiles that cannot support the same long periods of shelf-life of vitaMK7.
