Description

Feed grade vitamin K3-MNB

Basic Information

Vitamin K3
Product Type	Fat-soluble vitamin, feed grade
Available Forms	MSB (Menadione Sodium Bisulfite) MNB (Menadione Nicotinamide Bisulfite)
CAS No. (MSB.3H2O)	57414-02-5
CAS No. (MNB)	73581-79-0
Available Form	White crystalline powder
Common Specifications	MSB: menadione content ≥ 94% MNB: menadione content ≥ 43%
Main Application	Animal feed premixes

Product Overview

Vitamin K3 (Menadione) feed grade has two equivalent commercial forms: MSB (Menadione Sodium Bisulfite) and MNB (Menadione Nicotinamide Bisulfite). Both are yellow crystalline powders designed for animal nutrition. MSB is a cost-effective option for conventional feed production, while MNB features enhanced heat and moisture stability for demanding feed granulation processes. They are essential vitamin K sources for livestock and aquatic animal feed formulations.

MSB VS MNB — Core Difference Comparison Table

Comparison Item	MSB (Menadione Sodium Bisulfite)	MNB (Menadione Nicotinamide Bisulfite)
Menadione Content	≥ 94% (high concentration)	≥ 43% (lower concentration)
Stability	Lower; sensitive to moisture, heat and oxidation	Better; more stable in premix blending
Solubility	Freely soluble in water	Soluble in water
Primary Use	Concentrated feed premix, vitamin preblend	Multi-vitamin premix, stable feed formulation
Handling	More reactive, requires careful storage	Easier to handle, better flowability
Cost Efficiency	Higher activity per kg, more concentrated	Lower activity per kg, but more stable and convenient
Typical Customer	Feed premix manufacturers, vitamin preblend producers	Compound feed factories, integrated feed mills

Character

MSB and MNB are yellow crystalline powders. MSB provides reliable performance and cost advantages for general feed premix. MNB has outstanding resistance to high temperature and humidity, preserving activity during feed pelleting. Both materials blend smoothly with other vitamins and mineral ingredients in feed formulas.

Main Functions

1.Essential Vitamin K Nutrient for Animals: Both MSB and MNB supply vital vitamin K to support normal blood coagulation function in livestock and aquatic animals.

2.Two Parallel Feed Grade Options for Different Processing Requirements: MSB is economical for standard feed formulations. MNB offers superior stability under high temperature and humid feed processing conditions.

3.Good Compatibility for Feed Premix: Compatible with other feed vitamins and minerals, maintaining activity during feed manufacturing and storage.

4.Cost-Effective Feed Fortification Source: Widely adopted vitamin K raw materials for animal nutrition formulations.

Applications

Animal Feed: MSB and MNB are widely used in livestock and aquaculture feed premixes and complete feed. MSB is suitable for general feed formulations, while MNB is preferred for high-temperature granulation processes requiring stronger stability.

Our Quality

As a professional ingredient supplier, we do not operate manufacturing facilities. Instead, we build robust quality‑assurance workflows across our whole supply chain to safeguard consistent product performance for every shipment

Strict Supplier Due‑Diligence

Before entering any partnership, we carry out on-site factory visits and assess industry reputation, followed by multi-stage qualification reviews. We validate production qualifications, export track records, quality management systems and complete certification packages. New suppliers must pass sample evaluation, and only fully vetted top-tier factories are admitted to our approved supplier pool

Batch‑by‑batch Document Verification

For every order, we cross‑check factory‑issued test documents against agreed specifications including FCC, USP, EP, AJI, CP or your customized requirements. We will not forward documents to customers until key indicators are fully aligned with specifications. This step avoids inconsistent or mismatched documentation common in raw‑material trade.

Independent Third‑party Testing Coordination

Upon client request, we can arrange independent laboratory inspections from recognized third‑party institutions. We manage sample delivery, test protocol communication and report follow‑up to support your market compliance needs.

Quality Closure & Continuous Improvement

We keep traceable records for all delivered batches. If any quality concern arises, we act as your single point‑of‑contact to trace root causes with source factories, drive corrective actions and deliver practical resolution plans. Client feedback is systematically collected to optimize our supplier management and document‑review procedures.

We provide a comprehensive set of compliance documents to support your import and registration work. Our available documentation includes but is not limited to:

★ ISO Certification ★ Halal Certificate

★ Kosher Certificate ★ IP certificate

★ Haccp certificate ★ Allergens with Glutens
