Chromium (Cr) is an essential nutrient required for normal
sugar and fat metabolism. It potentates the action of insulin. Chromium occurs primarily
in the trivalent and hexavalent forms; the form in higher organisms is trivalent. This
mineral occurs throughout the body with highest concentrations in the liver, kidney,
spleen and bone. Chromium is an essential trace mineral required for normal protein, fat
and carbohydrate metabolism.
The use of chromium picolinate supplements supports a normal glycated homoglobin level in
individuals with type II diabetes reports a study in this months journal Diabetes,
an official publication of the American Diabetes Association.
This clinical trial was conducted by Dr. Richard Anderson and his coworkers at the
Beltsville Human Nutrition Research Center, United States Department of Agriculture
(USDA), in Beltsville, Md. and by Dr. Nanzheng Cheng and her colleagues from the Beijing
Medical University in Beijing, China.
In this double-blind, placebo-controlled clinical trial, 180 adult patients with the most
common form of diabetes (type II or adult-onset) were randomized into one of three equal
groups who received either 200 micrograms of chromium as chromium picolinate, 1,000
micrograms (one milligram) of chromium as chromium picolinate or placebo. All supplements
were taken daily for four months, during which time the patients were instructed not to
change their customary diets, exercise regimens or medications.
