Chromiun

Scientists believe that insulin uses chromium as an assistant (technically, a cofactor) to “unlock the door” to the cell membrane, thereby allowing glucose to enter the cell.More than 15 scientific studies support the safety and role of chromium in improving insulin function and glucose metabolism in people with type 2 diabetes and related conditions. “There is strong scientific evidence to suggest that supplemental chromium picolinate may improve insulin sensitivity, blood glucose control, and cardiovascular risk factors in adults with type 2 diabetes,” according to Dr. Kaufman, former president of the American Diabetes Association and specialist in pediatric endocrinology.

Details of these studies are outside the scope of this article.Science News Online reported in April 2005 that Robert DiSilvestro and Emily Dy of Ohio State University showed data at the Experimental Biology 2005 meeting in San Diego indicating that only the picolinate form of chromium is absorbed well by the body. The report stated that according to Robert DiSilvestro about 40 percent of chromium picolinate was absorbed by people taking chromium supplements in one experiment. DiSilvestro added that absorption of other forms of the mineral in supplements ran as low as 1 percent and only about 10 percent of any form of chromium in foods is typically absorbed. (Science News Online 16/4/2005; Vol. 167, No. 16).Additionally, an animal study conducted at the U.S. Department of Agriculture and published in the Journal of the American College of Nutrition found that chromium picolinate was better absorbed by the tissues (e.g., liver and muscle) than chromium nicotinate and chromium chloride. Absorption into the tissue is important because for a mineral to be beneficial, it must survive the digestive tract and reach the bloodstream. Otherwise, minerals pass through the body, leaving it void of necessary nutrients. (Medical News Today 7/2/2007).
