I want to know where my company can purchase vitamin b-complex for use
in supplements (for humans). Please note that I'm looking for raw
material, not finished supplements. I prefer european suppliers but
any supplier that ship worldwide is fine.

Hi, 

The BASF Chemical Company is in Ludwigshafen (and many other places).
They produce chemical vitamins in bulk.

DSM

--"DSM, however, has signaled that it is taking the approach of ?if
you can't beat ?em, join ?em' where Asia is concerned. Earlier this
month it announced the opening of its first research and development
centre in China, giving the Nutritional Products division production
resources in the region.

The Dutch company has recently entered into joint ventures with
Chinese vitamin makers, and this week is expected to reveal details of
a joint lab with Fudan University that may provide a link to
Nutritional Products activities."--
