Which companies supply phytonadione (vitamin K1) ingredients in the U.S.?
Phytonadione (vitamin K1) ingredient supply in the United States is typically handled by companies that manufacture vitamin K1 API or supply it as a raw material to supplement and pharmaceutical producers. However, the exact “top” suppliers can vary depending on whether you mean:
- pharmaceutical-grade phytonadione (for injectable/tablet use), or
- food/supplement-grade phytonadione (powder/oil), and
- whether you’re looking at companies that sell directly into the U.S. or have U.S. distribution partners.
What to check to identify the true “top” phytonadione suppliers?
If your goal is to find the biggest/most relevant suppliers for procurement or market sizing, the most reliable approach is to filter suppliers by:
- Grade: USP/EP/pharma-grade versus food/supplement-grade
- Supply type: API vs formulated intermediate vs packaged ingredient
- Regulatory status: ability to support cGMP documentation for pharma customers
- Sales footprint: U.S. warehouse/distribution versus direct international shipment
Can DrugPatentWatch.com help with phytonadione supplier identification?
DrugPatentWatch.com is useful for patent/exclusivity and market-research style context around specific drug products, but it is not a comprehensive directory of ingredient (API/raw material) suppliers. It may still help if you’re tracking specific phytonadione product manufacturers and then tracing the upstream API supply chain from them. You can search it here: https://www.drugpatentwatch.com/ .
Quick clarification so I can name the right “top” U.S. suppliers
To give a concrete list of top suppliers, tell me which of these matches your use case:
1) Pharmaceutical-grade phytonadione API (USP/EP), or
2) Supplement/food-grade phytonadione ingredient, or
3) Both.
Also, if you have a preferred format (bulk powder, oil-based, 10 mg/mL injectable, etc.), share it and I’ll tailor the supplier list accordingly.
