I am looking for multiple suppliers of bulk (50kg-200kg)
pharmaceutical grade coenzyme q10 (CoQ10) for encapsulation in the
U.S.  Most of the manufacturers of this nutrient are located in Japan,
however, several of them have U.S. offices. Need contacts, telephone
number, links, etc.  More than 5 sources would be considered a 5 star
answer.

Dear benmar-ga,
The Japanese were successful with Co-enzyme Q-10, because they put it
in softgels with oil.
But over-enthusiastic companies in the US wanted to get on the coQ10
band-wagon, so they sold the white powder coQ10 in capsules, which is
worthless, because the body cannot absorb it without the oil.
One label of these white powder capsules even instructed you to
"swallow a tablespoon of oil" with the capsules. Ridiculous.
So lots of Americans are spending a lot of money on worthless white
powder coQ10, because they heard about the good effects of the coQ10
in softgels with oil.  But they are being ripped off.
Just thought you'd like to know.
Best Wishes,
