Chromium picolinate is the chemical compound that is sold as a nutritional supplement to prevent or treat chromium deficiency. This bright-red coordination complex is derived from chromium(III) and picolinic acid. Small quantities of chromium are needed for glucose utilization by insulin in normal health, but deficiency is extremely rare in developed nations.
Health claims and debates
Some commercial organizations promote chromium picolinate as an aid to body development for athletes and as a means of losing weight. But a number of studies have failed to demonstrate an effect of chromium picolinate on either muscle growth or fat loss.
Claims have supported the benefit of the picolinate form of chromium supplementation in reducing insulin resistance, particularly in diabetics. A meta-analysis of chromium supplementation studies showed no association between chromium and glucose or insulin concentrations for non-diabetics, and inconclusive results for diabetics. But this study has been challenged on grounds that it excluded significant results.
There is concern that chromium picolinate is more likely to cause DNA damage and mutation than other forms of trivalent chromium., but these results are also debated. Other studies indicate that chromium picolinate is safe even at very high doses.
