18 Jul 2017 --- After a slow period at the beginning of the 2000s, the market for vitamin K2 has increased by more than 50 percent a year for the past four years, mainly as the result of the publication of a wide range of groundbreaking studies on, for example, bone health and cardiovascular health. According to Eric Anderson, Senior Vice President of Global Marketing and Business Development at NattoPharma, this increase can be credited mainly to a decade of meticulous research supported by the Norwegian vitamin K2 company.
