Vitamin K2

Vitamin K2 (CAS 11032-49-8), also known as menaquinone, is a fat-soluble vitamin used across food fortification, dietary supplement manufacturing, and pharmaceutical formulation. The MK-4 subtype (menatetrenone) is the most commercially prominent short-chain form, while longer-chain variants such as MK-7 are increasingly specified in premium supplement applications.

In dietary supplement manufacturing, it is formulated into softgels, tablets, and capsules targeting bone and cardiovascular health product lines for global distribution. Food and beverage producers incorporate it into fortified dairy alternatives, functional drinks, and enriched infant formula to meet specific nutritional labeling requirements.

Pharmaceutical manufacturers use menatetrenone as an active ingredient in prescription and OTC products, particularly in markets where it holds official drug status. In animal nutrition, it is included in poultry and livestock feed premixes to support coagulation function and bone development across various agricultural sectors.

The material is supplied as a fine powder, oil suspension, or microencapsulated form to support dispersion in both oil-based and water-based manufacturing systems. Standard grades include food-grade and pharmaceutical-grade material, with USP and Ph.Eur. specifications available for highly regulated industrial applications.
