Chromium For Insulin Function

Chromium appears to make insulin function more efficiently by enhancing the uptake of glucose from the blood into the cell. Chromium increases the number of insulin receptors on the cell membrane and enhances insulin binding to cells. It also activates insulin receptor kinase, leading to increased insulin sensitivity. [5] Because of chromium's role in insulin activity, researchers have looked at using the trace mineral to help diabetics control their blood-sugar levels. Additionally, work has been done on chromium's utility in depression and cholesterol management.

Chromium is an essential trace mineral present in trace amounts in some foods such as meat, whole grains, oleaginous plants and legumes. This mineral is currently being used as a food supplement in sports in order to promote a greater muscle mass gain and loss of body fat. However, the participation of chromium in metabolism is limited to an increase on the insulin sensitivity by the binding of four chromium atoms to a specific intracellular protein denoted apochromodulin that, in turn, binds to the insulin receptor of peripheral tissue cells concomitantly with insulin, although at another site located in the intracellular domain. This binding amplifies the cascade of intracellular signals responsible for stimulating the translocation of GLUT4 and increases glucose and amino acid uptake. Chromium may also inhibit the key enzyme in the synthesis of cholesterol, thus improving the lipid profile of individuals with dyslipidemia. The alterations on the body composition occurring in individuals who practice sports are not significant but, on the other hand, chromium supplementation may improve the lipid profile and the symptoms of type II diabetes of individuals affected by these types of metabolic unbalances.
