Product role

Where Vitamin K3 fits

Vitamin K3 is part of the vitamins and vitamin-like nutrients group. Buyers typically evaluate this product by matching the active form, menadione-equivalent potency, assay method, carrier system, physical form, intended species, premix compatibility, processing conditions and documentation requirements.

In commercial feed manufacturing, Vitamin K3 is usually supplied as a stabilized menadione derivative rather than pure menadione. Common feed-use forms may include menadione sodium bisulfite, menadione sodium bisulfite complex and menadione nicotinamide bisulfite, depending on the supplier specification and applicable market rules.

Atlas Feed Additives can coordinate international supplier options for feed mills, premix producers, distributors and integrators that need consistent feed-grade Vitamin K3 material, export documentation, packaging clarity and quotation support.

Typical applications

  • Complete feed premixes, vitamin-mineral premixes and concentrates for multiple species.
  • Poultry feeds, including broiler, layer, breeder and turkey programs.
  • Swine feeds, including nursery, grower-finisher and sow diets.
  • Ruminant premixes for dairy cattle, beef cattle, calves, sheep and goats.
  • Aquaculture feeds where vitamin fortification must be aligned with processing and storage conditions.
  • Pet food, specialty feed and companion animal premixes where permitted by the destination market.
  • Starter feeds, high-performance diets and transition-period nutrition programs designed by nutritionists.

Buyer quality checklist

  • Active form: menadione sodium bisulfite, menadione sodium bisulfite complex, menadione nicotinamide bisulfite or another permitted form.
  • Declared menadione-equivalent potency and assay method.
  • Stabilization system, carrier type and physical form.
  • Particle size, bulk density, flowability, dust level and blending behavior.
  • Moisture, loss on drying, assay, related substances and contaminant limits.

Procurement note

Ask for the right specification before comparing prices.

Price comparisons are meaningful only when active form, potency, assay basis, carrier, particle size, packaging, origin, shelf life and documentation are aligned. Vitamin K3 products can differ significantly in menadione-equivalent content, stabilization approach, premix compatibility and handling properties.

When reviewing quotations, buyers should confirm whether the offer is based on gross product assay or menadione-equivalent potency. The same product name may not always mean the same active level. For premix production, physical handling, stability and uniform distribution are often as important as price per kilogram.

Technical overview

What buyers should understand about Vitamin K3

Menadione-based vitamin source

Vitamin K3 is commonly associated with menadione, a synthetic vitamin K-related compound. In animal feed, menadione derivatives are used because they can provide vitamin K activity in feed fortification programs. The offered commercial form should always be confirmed because different derivatives can have different assay values, handling properties, stability profiles and regulatory status.

Common commercial forms

Feed-grade Vitamin K3 products may be supplied as menadione sodium bisulfite, menadione sodium bisulfite complex, menadione nicotinamide bisulfite or other supplier-specific forms permitted in the buyer’s market. These forms are often selected for practical handling, stability and use in premix or feed applications.

Potency basis is critical

Buyers should distinguish between total product content and menadione-equivalent potency. Two products with different derivatives or carriers may have different active contribution per kilogram. A precise comparison requires the specification, assay method and declared potency basis.

Stability depends on the full premix environment

Vitamin stability can be influenced by moisture, oxygen, heat, light, trace minerals, choline chloride, acids, aggressive premix components and storage duration. Vitamin K3 should be evaluated in the context of the full premix or feed matrix, not only as a standalone ingredient.

Species and feed applications

Where Vitamin K3 may be evaluated

Poultry

Vitamin K3 is commonly evaluated in poultry premixes and complete feeds because poultry programs rely on precise micronutrient fortification. Broiler, layer, breeder and turkey formulas may include Vitamin K3 according to species requirements, feed type, local regulations and nutritionist guidance.

  • Broiler starter, grower and finisher premixes.
  • Layer and breeder premixes where vitamin consistency is commercially important.
  • Turkey and specialty poultry feeds requiring species-specific fortification.
  • Vitamin-mineral premixes where uniform distribution and stability are key purchasing criteria.

Swine

In swine nutrition, Vitamin K3 may be included in nursery, grower-finisher and sow premixes according to formulation targets and local rules. Buyers should check compatibility with trace minerals, acids and other premix components when selecting the grade.

  • Nursery feeds and starter premixes for young pigs.
  • Grower-finisher formulas requiring reliable vitamin fortification.
  • Sow feeds for gestation and lactation programs.
  • Concentrates and basemixes for integrated feed production.

Ruminants

For dairy cattle, beef cattle, calves, sheep and goats, Vitamin K3 may be reviewed as part of vitamin-mineral premixes, concentrates and specialty nutrition programs. The form and inclusion should be selected according to target species, ration design and market authorization.

  • Dairy premixes and concentrates.
  • Beef cattle receiving, adaptation and finishing feeds.
  • Calf starter and milk-replacer-related nutrition programs where permitted.
  • Small ruminant premixes and mineral-vitamin concentrates.

Aquaculture and companion animals

In aquaculture and pet food, Vitamin K3 suitability depends on species, feed processing, extrusion stability, water stability, regulatory status and label requirements. Buyers should confirm whether the selected form is permitted and technically appropriate before purchase.

  • Fish and shrimp feeds requiring vitamin premix fortification.
  • Extruded feeds where processing and shelf-life stability must be reviewed.
  • Pet food and companion animal premixes where permitted by market rules.
  • Export applications requiring clear product identity and market-specific documentation.

Premix formulation guide

How Vitamin K3 is used in practical feed programs

Micronutrient fortification

Vitamin K3 is normally used in small quantities as part of a broader vitamin and mineral premix. Because the inclusion rate can be low, uniform distribution is important. Buyers should pay attention to particle size, bulk density, carrier compatibility and mixing behavior.

Premix stability

Vitamin K3 stability should be reviewed together with the entire premix system. Trace minerals, choline chloride, moisture, acidity, oxygen exposure and storage time may affect sensitive vitamins. Buyers should request stability guidance or use supplier recommendations for premix design.

Processing and finished-feed conditions

If Vitamin K3 is used in pelleted, extruded or heat-processed feed, the supplier’s guidance on heat exposure and finished-feed stability should be reviewed. Processing conditions, feed moisture and storage time can influence vitamin retention.

Regulatory and label alignment

Vitamin K3 forms and claims should be aligned with the rules of the destination market. Buyers should confirm whether the active form, label description, inclusion guidance and documentation package are acceptable for import and use.
