New clinical study uncovers mechanism by which chromium picolinate may enhance insulin sensitivity

Effective and safe complementary nutrition therapy



The results of a new double-blind randomized placebo controlled human trial of people with type 2 diabetes revealed a potential mechanism that may explain the ability of chromium picolinate to improve insulin resistance in human skeletal muscle – the primary site for glucose metabolism. These data suggest that when chromium picolinate is added to the diet, insulin sensitivity improves for people with diabetes, a chronic disease that affects 194 million people worldwide. The findings were presented by Dr. William T. Cefalu from the University of Vermont College of Medicine, USA at the 18th International Diabetes Federation Congress.

Research suggests that the potential in vivo mechanism of chromium picolinate on insulin action in human skeletal muscle may occur by increasing the activation of Akt phosphorylation -- an intracellular insulin dependent protein that facilitates the uptake of glucose into cells.


"This study demonstrates that those individuals with type 2 diabetes who supplemented their diet with chromium picolinate had an enhanced activity of the protein compared to those who were on placebo," stated Dr. Cefalu. "As this intracellular pathway is implicated in contributing to insulin resistance, this represents a possible mechanism to explain chromium picolinate’s beneficial effect on insulin sensitivity as observed in several clinical studies."

The clinical trial
The double-blind, placebo controlled trial, included two cohorts of subjects with type 2 diabetes who were treated with either sulfonylureas (a class of diabetic drugs that increase insulin secretion), or a diet program. Both groups were randomized to receive either chromium picolinate (1000 mcg) daily or placebo. The most accurate measure of insulin sensitivity, hyperinsulinemic, euglycemic clamp studies, were used to assess the efficacy of glucose uptake on all subjects prior to randomization and at the end of the study. Of the 16 subjects, those randomized to chromium picolinate had a mean increase in insulin sensitivity of 8.9%, while the placebo group had a mean decrease of 3.6%. In addition, insulin-stimulated Akt activation was significantly increased at the end of the study compared to those subjects on placebo. No adverse events were reported.

A Cost Effective Nutrition Therapy
The World Health Organization (WHO) estimates that four to five percent of health budgets are spent on diabetes-related illnesses and that people with diabetes incur medical costs two to five times higher than people without diabetes.

Chromium is an essential mineral that is a co-factor of insulin. "By applying rigorous science, we hope to show it’s potential to improve the quality of patient care for people with diabetes and reduce cost of therapy," said James Komorowski, MS, Vice President of Technical Services and Scientific Affairs, Nutrition 21, Inc., which supplied Chromax? chromium picolinate for the study. Chromax chromium picolinate is the most clinically tested brand of chromium with proven efficacy for support of glucose metabolism. "This new research further supports the large body of scientific evidence showing chromium picolinate is a safe and effective addition to the diet for people with type 2 diabetes seeking optimal control of their blood sugar levels."


Nutrition 21 provided an unrestricted research grant and Chromax® chromium picolinate for the trial. Nutrition 21 is a leading developer and provider of nutritional products, whose health benefits are substantiated by clinical research. The Company markets Chromax chromium picolinate, the leading brand of chromium, and holds 35 patents for nutrition products, 22 for chromium compounds and their uses.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
