Hi XXXXXX,
Yes, you have heard the phrase "helps to regulate blood glucose levels"
about chromium and brewer's yeast.  This actually refers to its use with
diabetics where regulating their glucose actually means to LOWER their
glucose.  Unfortunately it does not raise it when it is low.  In the March
2000 issue of Veterinary Medicine there is a good article about Chromium
and Vanadium.  The article is titled: Two transition metals show promise in
treating diabetic cats.  It has a list of 18 references of both human and
animal articles.
 
Hope that helps,
