Chromium
Chromium’s main functions appear to be linked with carbohydrate and lipid metabolism. It is essential to consider that chrome is also required for insulin action, the hormone responsible for controlling glucose levels in the blood.
According to human research, subjects with adequate dietary chromium had improved control over blood glucose and also showed a better blood lipid profile—the characteristic of chromium deficiency directly impaired glucose tolerance that can be enhanced by chromium supplementation. Moreover, chromium is not known to show toxicity.
