Chromium (III) has a particular transportation mechanism; because of this, only limited quantities of it pass in the cells. However, numerous in vitro studies specified that higher levels of Cr (III) in the cell could cause DNA impairment. Reasonable uptake of Cr (III) via dietary supplements causes no risk, whereas its severe oral toxicity varies between 1.5 and 3.3 mg/kg.

The severe toxicity of chromium (VI) is because of its strong oxidation properties. Once it enters the bloodstream, it harms the kidneys, the liver, and blood cells by oxidation reactions (CGWB 2014). Excess Cr (VI) can cause damage to the nervous system, fatigue, irritability, skin allergies, dermatitis, dermal necrosis, and dermal corrosion (Singh et al. 2011).
