Only three of nine studies provided information on adverse events, so we were unable to determine whether chromium picolinate supplements are safe and whether any potential harms may increase with dose. We were unable to find good evidence that this potential weight loss effect increased with increasing dose of chromium picolinate. When the results obtained from the doses of chromium picolinate investigated (200 µg, 400 µg, 500 µg, 1000 µg) were pooled, study participants lost around 1 kg of body weight more than participants receiving placebo. The evidence is current to December 2012. A total of 622 participants took part in the studies, 346 participants received chromium picolinate and 276 received placebo. with a body mass index between 25 and 29.9 kg/m 2 defining being overweight and a body mass index of 30kg/m 2 or more defining obesity). We included nine randomised controlled trials which compared the efficacy and safety of 8 to 24 weeks of chromium supplementation and placebo in overweight or obese adults (i.e. Chromium picolinate is one of several chemical compounds of chromium sold as a nutritional supplement as a potential aid to weight loss. Chromium is also said to suppress the appetite and stimulate the production of heat by the body, thus increasing energy expenditure. It is generally believed that chromium may help to reduce a person's weight by decreasing the amount of fat in the body. Chromium increases the activity of insulin, and dietary supplementation with chromium has produced improvements in glucose metabolism which may lower blood glucose being important for overweight people with diabetes. the chemical reactions involved in breaking down these molecules to a form suitable for absorption by the body). Are chromium supplements useful for reducing body weight in overweight or obese adults?Ĭhromium is an essential nutrient (trace element) required for the normal metabolism of carbohydrate, protein and fat (i.e.
