This has led to a number of changes in the U.S. market, including a number of acquisitions/mergers and some demises. DSM (Heerland, the Netherlands) purchased Roche Group (Basel, Switzerland), and BASF (Ludwigshafen, Germany) took over the Takeda (Lincolnshire, Ill.) vitamin business. Rhone-Poulenc broke up, while new vitamin- and feed-ingredient company Adisseo (Alpharetta, Ga.) was formed.
Leading this drastically altered market is Roche/DSM, with 27% share of the global vitamin business, followed by the 21% share held by BASF. As a whole, Chinese producers maintain a strong 24%, but BCC notes that this share is split among many small companies.
