Chromium

Chromium, as trivalent (+3) chromium, is a trace element that is naturally present in many foods and available as a dietary supplement. Chromium also exists as hexavalent (+6) chromium, a toxic by-product of stainless steel and other manufacturing processes [ 1, 2 ]. This fact sheet focuses entirely on trivalent chromium.
