We ship to over 50 countries, with cost-effective factory-direct prices and worldwide logistical networks.

What Is Vitamin K3 Powder?

This substance (chemically menadione) is a synthetic derivative of vitamin K that is necessary for blood coagulation and bone metabolism. This water-soluble molecule is more stable to high temperature processing than naturally-occurring K1 and K2 forms.

The yellow crystalline form enables repeatable absorption in medicinal and animal feeding applications. As it is produced synthetically, it is consistent batch to batch and does not have the seasonal changes that come with plant derived vitamins.

Our pharmaceutical grade material fulfills the most demanding criteria of international pharmacopeias. Each batch undergoes stringent HPLC analysis to confirm molecular purity and remove any possible contaminants.

Functions

The product has important biological functions in many metabolic pathways:

Enhances blood coagulation. It stimulates the liver to produce prothrombin and reduces the clotting time by 30-40% in deficient people. In clinical investigations INR readings rapidly normalized within 48-72 hours after dosing.

Bone Mineralization Support: Promotes the carboxylation of osteocalcin proteins to enhance the efficacy of calcium binding in bone matrix. Studies show that when coupled with calcium supplementation programs, it increases bone density by 15-20%.

Antioxidant Protection: Eliminates free radicals via electron transfer processes, protecting cell membranes from oxidative damage. Lab tests demonstrate 25% decrease in indicators of lipid peroxidation.

Application Fields

The product’s adaptability covers three main B2B segments

Animal Feed Industry: Used in poultry and swine premixes at levels of 1-3 mg/kg. The crystalline form is temperature resistant up to 80°C and retains 95% activity for six months in full meals.

Pharmaceutical manufacturing: Used in injectable solutions and oral solid dose forms. The powder has consistent particle size (98% passes 80-mesh) and is suitable for homogenous mixing in tablet compression at rates of 100,000 tablets/hour or more.

Aquaculture Nutrition: A vital addition in fish and shrimp feed compositions. Its water-stable properties reduce leaching losses and preserve nutrient integrity over the 8 to 12 hour feeding window in the aquatic environment.

FAQ

Q: What is the difference between pure product and diluted feed grade?

A: For pharmaceutical applications where great potency in a small amount is needed, 99% pure powder is ideal. Feed-grade formulations (typically 20-50% on carriers such as rice hulls) simplify mixing into ton-scale animal feeding batches, avoiding segregation of microgram doses.

Q: How does the product perform under high-temperature pelleting?

A: The crystalline structure remains stable up to 160°C for short durations (30-90 seconds), retaining >92% activity post-pelleting. For extended extrusion processes, we recommend our coated grade to achieve >95% potency retention.

Q: Is your product suitable for aquatic feed formulations?

A: Yes. Our powder is low in water solubility leaching (<3% loss over 12 hours), suitable for shrimp and fish feeds where there is extensive water exposure before eating.

Q: What paperwork is necessary to show regulatory compliance in EU and USA?

A: We give lot specific Certificates of Analysis, Heavy Metals Reports, Microbiological Test Results and allergy assertions. Feed-grade substance has AAFCO compliance documents.

Q: Can small orders be accommodated for R&D purposes?

A: Absolutely. We offer 100g-1kg samples for formulation trials. Technical support includes dissolution testing and stability study guidance at no additional cost.
