Which U.S. companies supply phytonadione (vitamin K1)?
Phytonadione (vitamin K1) is supplied in the U.S. by multiple pharmaceutical manufacturers and distributors, typically for hospital and retail pharmaceutical channels. The biggest “supplier” names in practice are usually the companies that manufacture branded products or the large distributors that move finished drug products into U.S. healthcare systems.
What form do you mean—injectable, oral tablets, or both?
“Phytonadione” is sold in different dosage forms, and supplier lists can change depending on whether you need:
- Injectable phytonadione (commonly used in hospitals)
- Oral phytonadione (often tablets/capsules)
- Bulk/active pharmaceutical ingredient (API) sourcing versus finished-dose drug products
If you’re sourcing for manufacturing (API/bulk), the supplier set will differ from sourcing for pharmacy/hospital procurement (finished drug).
Are you looking for manufacturers or for distribution (wholesalers)?
In U.S. procurement, “supplier” can mean either:
- Manufacturers (companies that make the branded/generic drug product)
- Wholesalers/distributors (companies that sell to hospitals and pharmacies)
If you tell me which procurement route you’re using (GPO/hospital pharmacy, retail, or API procurement), I can narrow the list to the most relevant kinds of suppliers.
What’s the quickest way to identify top suppliers for your exact need?
To produce an accurate “top suppliers” list, the key details are:
- Dosage form: injectable vs oral
- Strength (for example, mg per mL for injectable)
- Brand vs generic vs API
- Intended buyer: hospital/retail vs manufacturing/API supply
- Packaging size (single-dose vials vs multi-dose, etc.)
Share those details and I’ll tailor the supplier list to your use case.
If you share your target SKU, I can give a concrete supplier shortlist
If you paste the exact product name (or strength and form), I can identify the main companies involved in that specific U.S. phytonadione product supply chain (manufacturer/labeler and major distribution channels) and filter out irrelevant sources.
