Chromium Picolinate

A diet that is rich in junk food promotes poor insulin metabolism; a condition where muscles desensitize to insulin. This condition makes the job of efficient nutrient transport much more difficult and worst of all, it promotes fat accumulation. Years ago, research showed that supplementation with chromium picolinate improved the sensitivity of insulin receptors in muscle cells in people diagnosed with insulin resistance (one step away from type-2 diabetes). However, the results of a recent study suggest that chromium supplementation may also help healthy people improve their blood sugar metabolism. That’s great news for bodybuilders.

Excess blood sugar from large meals is one cause of insulin resistance. High blood sugar levels also prevent fat utilization for fuel. In this study, a group of fit young men were given 400 or 800 micrograms of chromium picolinate or a placebo every day for 16 weeks. Results of this study showed that supplementation with chromium picolinate reduced blood sugar faster than the men given the placebo and therefore, improved insulin metabolism.

The results of a study presented last month at the annual Experimental Biology Meeting in San Diego, showed that chromium picolinate is the best absorbed form of chromium. A single dose (200mcg) of chromium picolinate produced an increase of 625% compared to baseline values, far better than any other form of chromium.

The researchers compared the absorption of four types of chromium, each administered in a single dose to 12 healthy young adults with normal body weight. The test was repeated at two-week intervals, each time with a different type of chromium. While chromium picolinate produced the best results, chromium chloride showed the worst absorption (many of the mainstream multivitamin-mineral supplements use this form of chromium).

A new study has shown that daily supplementation with chromium picolinate increases brain activity in older people experiencing early memory decline.

Functional magnetic resonance imaging (fMRI) scans showed that a daily dose of 1,000 micrograms of chromium picolinate led to greater activation in various parts of the brain in these participants.

The study completed by researchers from the University of Cincinnati demonstrated that older adults taking chromium picolinate exhibited greater brain activation while performing a cognitively demanding task. This study included about 30 people and it adds to a growing body of science demonstrating health benefits from chromium picolinate.

Chromium is an essential trace mineral that occurs naturally in very small amounts in some foods. It is poorly absorbed by the human body but is known to play an important role in the metabolism of carbohydrate, fat and protein. Several reports have indicated that chromium picolinate is better absorbed by humans than other forms of the mineral.

Enzymes are special proteins that are the catalyst of virtually every biological function in the body. Enzyme reactions are regulated by the addition of phosphate groups to the enzyme. These phosphate groups act like "switches" that turn an enzyme on or off and it appears that a chromium complex (a group of four chromium molecules) stimulate a phosphorylating enzyme that binds a phosphate group to protein. This makes the enzyme highly active. Recent work* showed that human cells incubated with chromium and insulin, increased insulin's effectiveness seven fold by stimulating this enzymatic activity. Chromium appears to "unblock" insulin's receptors and activate this particular enzyme that allows insulin to bind more effectively to receptor sites in cells.
