What Is Vitamin K3 Powder?

Vitamin K3 powder, also known as Menadione, it is a synthetic form of Vitamin K that plays a vital role in blood coagulation, bone metabolism, and cardiovascular health. Unlike natural forms such as Vitamin K1 (Phylloquinone) and Vitamin K2 (Menaquinone), Vitamin K3 is a water-soluble compound, making it more stable and widely used in animal nutrition and feed industries rather than direct human supplementation.

Vitamin K3 is typically supplied in several derivative forms—Menadione Sodium Bisulfite (MSB), Menadione Sodium Bisulfite Complex (MSBC) and Menadione Nicotinamide Bisulfite (MNB)—to enhance stability, solubility, and bioavailability.

Chemically, Vitamin K3 is 2-methyl-1,4-naphthoquinone, with the molecular formula C11H8O2. It appears as a yellow crystalline powder and is characterized by its high stability under heat and light, which makes it ideal for premix formulations and industrial uses.

Vitamin K Family Overview

Summary: Vitamin K3 is the synthetic, water-soluble form of Vitamin K, designed primarily for nutritional enhancement in livestock and poultry.

Functions and Benefits of Vitamin K3

1. Essential for Blood Coagulation

Vitamin K3 is a precursor for synthesizing prothrombin and other clotting factors in the liver. Adequate Vitamin K3 helps prevent hemorrhagic disorders and ensures proper blood clotting in animals.

2. Supports Bone Development

By promoting the synthesis of osteocalcin, a protein that binds calcium to bones, Vitamin K3 helps maintain strong bone structure and density, reducing the risk of bone fragility.

3. Improves Feed Efficiency and Growth

In livestock and poultry, Vitamin K3 supplementation enhances feed utilization efficiency, weight gain, and overall growth performance.

4. Enhances Liver and Immune Function

Vitamin K3 aids in detoxification and supports the immune system, improving the animal’s resistance to infections and environmental stress.

5. Prevents Vitamin K Deficiency

Vitamin K deficiency can cause subcutaneous hemorrhages, weak bones, and poor growth in animals. Supplementation with Vitamin K3 ensures balanced nutrition and better health outcomes.

Applications of Vitamin K3 Powder

1. Poultry Feed

Vitamin K3 is widely used in chicken, duck, and turkey feed to prevent bleeding disorders, improve bone formation, and enhance egg production.

2. Livestock Feed

In pig and cattle feed, Vitamin K3 promotes healthy growth, bone strength, and feed efficiency, especially during fast growth periods or stressful conditions.

3. Aquaculture Feed

Its water-soluble nature makes Vitamin K3 suitable for fish and shrimp feed, where it prevents internal bleeding and supports proper skeletal development.

4. Pet Nutrition

In pet formulations, Vitamin K3 contributes to healthy blood clotting and strong bones, ensuring balanced nutrition for dogs and cats.

5. Veterinary Medicine

Vitamin K3 is used in vitamin premixes, injectables, and feed supplements to prevent hemorrhagic diseases and nutritional deficiencies in animals.
