Systematic review and meta‐analysis of the efficacy and safety of chromium supplementation in diabetes

The available evidence suggests favourable effects of chromium supplementation on glycaemic control in patients with diabetes. Chromium monosupplementation may additionally improve triglycerides and HDL‐C levels. Chromium supplementation at usual doses does not increase the risk of adverse events compared with placebo. Data on chromium combined supplementation are limited and inconclusive. Long‐term benefit and safety of chromium supplementation remain to be further investigated.
