Description

Menaquinones CAS NO 523-40-0 are a group of fat-soluble compounds, primarily known as Vitamin K2, which are essential for critical biological functions such as blood coagulation and bone metabolism. Their value lies in their superior bioavailability and longer half-life in the body compared to other vitamin K forms, making them a preferred choice for high-end nutritional and pharmaceutical formulations. This product is essential for manufacturers in the nutraceutical, pharmaceutical, and functional food industries seeking to enhance product efficacy with a premium, bioavailable vitamin K source.

Application

• Dietary Supplements & Nutraceuticals: A key active ingredient in capsules, tablets, and softgels targeting cardiovascular health, bone density support, and overall wellness.
• Pharmaceutical Formulations: Used in the production of prescription and over-the-counter medications for treating and preventing vitamin K deficiency and related coagulation disorders.
• Functional Food & Beverage Fortification: Incorporated into dairy products, health drinks, and meal replacements to add a clinically-backed nutritional benefit.
• Cosmeceutical Products: Applied in advanced skincare formulations for its purported role in supporting skin elasticity and health.
• Animal Nutrition & Feed Additives: Used in premium pet food and livestock feed to ensure proper growth, bone development, and health.
• Research & Biochemical Reagents: Serves as a high-purity standard and reagent in life science research, clinical studies, and diagnostic kit development.

Quality Control

Our Menaquinones are produced and tested under strict quality management systems to ensure they meet the high standards required for human consumption and research. We offer grades compliant with relevant pharmacopeial monographs (e.g., USP, EP) and food-grade specifications (FCC). Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, isomer profile, and impurity limits, ensuring traceability and consistency for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) at a controlled room temperature of 15-25°C (59-77°F) to minimize oxidation and degradation. The container must be kept in a cool, dry, and well-ventilated area away from heat sources and incompatible materials.
