Who is the largest manufacturer of leucovorin?
Based on widely reported industry supply information, the largest manufacturers of leucovorin (leucovorin calcium; folinic acid) are typically major global generics and branded-drug companies that supply hospital and pharmacy channels. However, the provided information here does not name a specific single “largest” manufacturer, and the identity can also change by market (U.S. vs. EU) and over time due to shortages, launches, and divestitures.
How to identify the largest leucovorin manufacturer by market
If you’re trying to find the single biggest supplier in a specific country or timeframe, the most reliable approach is to check:
- the current listed makers for the National Drug Code (NDC) products available in that market,
- procurement/supply data for hospital purchasing,
- and manufacturer listings tied to the drug’s regulatory filings.

Does “largest” mean by revenue, units, or supply?
People usually mean one of these when they ask for the “largest manufacturer”:
- largest by total sales revenue,
- largest by volume of doses/units shipped,
- or largest by market share in a specific country.
Without your intended definition (and which country), it’s easy to name the wrong company.
