Overview
Vitamin K (CAS 12001-79-5 ), also known as Phytol Naphthoquinone, is a fat-soluble vitamin used across food, pharmaceutical, and animal nutrition industries. It functions as a coagulation-supporting nutrient and antioxidant stabilizer in finished formulations.
In dietary supplements and functional foods, it is incorporated into capsules, tablets, and fortified products targeting bone health and cardiovascular nutrition. Pharmaceutical manufacturers use it as an active ingredient in injectable and oral dosage forms.
In animal feed and premix production, it is added to poultry, swine, and aquaculture feeds to meet nutritional specification requirements. Food producers also apply it in fortified dairy and infant formula products where regulatory nutrient thresholds must be met.
Vitamin K is supplied as a fine powder or oil-based concentrate, depending on the intended formulation matrix. Standard grades include USP , BP , and Ph. Eur. for pharmaceutical applications.
The material is also available in food-grade specifications compliant with FCC standards. Feed-grade material is available for agricultural and premix applications, typically in stabilized powder form for blending compatibility.
