Chromium picolinate

Abstract

Chromium picolinate is a dietary supplement gaining in popularity among Americans, especially those seeking a weight-reduction program. Although the mechanism(s) responsible for the purported actions of chromium picolinate have not been thoroughly investigated, studies suggest that the biochemical, physiological, and behavioral actions of chromium picolinate may be a consequence of the effects of picolinic acid on the central nervous system. Analogues of picolinic acid have been shown to induce profound alterations in the metabolism of serotonin, dopamine, and norepnephrine in brain. Thus, caution should be used with chromium picolinate supplements especially by individuals prone to behavioral disorders.
