Vitamin K2 Producers Buy Menadione Base as Menaquinone-4 Precursor
Supplement brands sell vitamin K2 for bone and cardiovascular health, and manufacturers of menaquinone-4 use menadione as a starting material that is alkylated with a terpenoid side chain. Menadione Base for Vitamin K2 Synthesis grows about 7.7% a year, and gross margins run 32% to 44% against 18% to 26% for plain sodium bisulfite. The trend needs high-purity base, low impurity levels and secure supply, and it rewards producers with pharmaceutical-grade documentation and long agreements with K2 makers in China, Japan and Europe. Impurity profiles and regulatory files decide which suppliers qualify.
