Chromium is involved in glucose metabolism and is the major mineral needed for insulin production. Chromium is beneficial for both high and low blood sugar problems.
"Chromium works with insulin to drive sugar from your blood into the tissues of your body for use or storage. This mineral is so important in sugar tolerance that severe deficiencies of it cause a diabetes-like illness to develop" Eades, Mary Dan, The Doctor's Complete Guide to Vitamins and Minerals, 1994, The Philip Lief Group, Inc.
Chromium GTF (glucose tolerance factor) is a very easily absorbed form of chromium, naturally derived from yeast in the safe trivalent form. GTF chromium is naturally bound to glycine, glutamic acid, cysteine and niacin. In contrast, industrial chromium is in a hexavalent form and is toxic.
