Chromium

Abstract

• Although chromium in human nutrition has been researched since the 1950s, much is still unknown • Poor bioavailability of chromium may be a protective mechanism against its potential toxicity • Vitamin c, picolinic, nicotinic and oxalic acids, as well as chronic resistance exercise and zinc or iron deficiency, enhance its absorption • increased urinary losses are evident with increased consumption of simple sugars, diabetes, lactation and any increase in cortisol levels • The mechanism behind chromium's key role in insulin signalling has been elucidated recently • Preliminary evidence supports chromium supplementation in the treatment of atypical depression and as a preventive measure against both cVD and type 2 diabetes in post-menopausal women.
