Since chromium may be helpful for the first three of these conditions, chromium deficiency has been proposed as the cause of syndrome X. 97Īccording to some researchers, impaired blood sugar control, high cholesterol, weight gain, and high blood pressure are all part of a bigger picture, called
When depression is characterized by rapid mood changes, excessive sleeping and eating, a sense of leaden paralysis, and extreme sensitivity to negative life events, the condition is called “atypical depression.” A very small (15 participants) double-blind, placebo-controlled study found thatĭepression 46 however, a much larger study failed to find statistically significant benefits. 41 In addition, among individuals taking beta-blockers, chromium may raise levels of HDL ("good") cholesterol. Grape seed extract might have a beneficial effect. However, one study suggests that chromium combined with 23-31,87Ĭholesterol levels have returned mixed results. Performance enhancer or aid to bodybuilding have yielded almost entirely negative results. One study failed to find benefit with a combination of chromium and However, most studies evaluating chromium's ability to promote
Since mild impairment of blood sugar control is believed to increase risk of heart disease, chromium supplementation might help reduce heart disease rates.Ĭhromium has been sold as a "fat burner" and is also said to help build muscle tissue. 6 In addition, nondiabetic individuals with mildly impaired blood sugar control might attain better control of blood sugar with chromium supplementation. One study suggests that chromium may also be useful for diabetes that occurs during Several, but not all, studies suggest that people with adult-onset (type 2) diabetes may show some improvement when given appropriate dosages of chromium. Chromium also might be helpful for milder abnormalities in blood sugar metabolism. One study suggests that chromium might aid in weight loss, as well, but other studies failed to find this effect.Ĭhromium has principally been studied for its possible benefits in improving blood sugar control in people withĭiabetes. The results have been somewhat positive: it seems fairly likely that chromium supplements can improve blood sugar control in people with diabetes. 83-85īased on chromium's close relationship with insulin, this trace mineral has been studied as a treatment for diabetes. LMWCr does not permanently bind chromium and is not a likely source of chromium in foods. Rather, chromium appears to act in concert with a very small protein called low molecular weight chromium-binding substance (LMWCr) to assist insulin's action. Scientists now believe that there is no such thing as GTF. However, subsequent investigation indicated that researchers were actually creating GTF inadvertently during the process of chemical analysis. Intact GTF was thought to be present in certain foods, such as Brewer’s yeast, and for that reason such products were described as superior sources of chromium. In the past, it was believed that to accomplish this the body first converted chromium into a large chemical called glucose tolerance factor (GTF). Scientists believe that insulin uses chromium as an assistant (technically, aĬofactor) to "unlock the door" to the cell membrane, thus allowing glucose to enter the cell. Insulin plays a starring role in this fundamental biological process, by regulating the movement of glucose out of the blood and into cells.
Chromium is a mineral the body needs in very small amounts, but it plays a significant role in human nutrition. Chromium's most important function in the body is to help regulate the amount of glucose (sugar) in the blood.
