Description

2-Methyl-3-[(2E,10E,14E,18E,22E,26E)-3,7,11,15,19,23,27,31-Octamethyl-2,10,14,18,22,26,30-Dotriacontaheptenyl]-1,4-Naphthoquinone is a high-purity synthetic form of Vitamin K2, specifically the menaquinone-7 (MK-7) isomer, a critical cofactor in the carboxylation of proteins involved in blood coagulation and bone metabolism. Its primary commercial value lies in its superior bioavailability and extended half-life compared to other vitamin K forms, making it the preferred choice for advanced nutraceutical and pharmaceutical formulations. This compound is essential for manufacturers in the dietary supplement, functional food, and clinical nutrition sectors seeking to develop products that support cardiovascular and skeletal health.

Application

• Dietary Supplements: Core ingredient in high-potency capsules, softgels, and tablets targeting bone density support and arterial health.
• Functional Food & Beverage Fortification: Used to enrich products like dairy alternatives, health drinks, and nutrition bars with bioactive Vitamin K2.
• Pharmaceutical Research & Development: Serves as a reference standard and active pharmaceutical ingredient (API) in studies and formulations for osteoporosis and vascular calcification.
• Clinical Nutrition: Incorporated into medical nutrition products designed for patients with specific deficiencies or metabolic bone disorders.
• Cosmeceuticals: Explored in advanced skincare formulations for its potential role in supporting skin elasticity and health.
• Animal Nutrition: Used in premium feed additives for livestock and pets to ensure proper bone development and health.
