Before chromium became a standard ingredient in total parenteral nutrition (TPN), people receiving TPN as their sole source of nutrition developed symptoms that were reversed within two weeks of chromium being added. Diagnosis Īccording to the Dietary Reference Intake review, neither plasma nor urine concentrations can serve as useful clinical indicators of chromium status. The claimed symptoms of chromium deficiency caused by long-term total parenteral nutrition are severely impaired glucose tolerance, weight loss, peripheral neuropathy and confusion.
Reviews report the changes as modest, and without scientific consensus that the changes have a clinically relevant impact. Dietary supplements containing chromium are widely available in the United States, with claims for benefits for fasting plasma glucose, hemoglobin A1C and weight loss. Whereas the authorities in the European Union do not recognize chromium as an essential nutrient, those in the United States do, and identify an adequate intake for adults as between 25 and 45 μg/day, depending on age and sex. The essentiality of chromium has been challenged. Cases of deficiency were described in people who received all of their nutrition intravenously for long periods of time.
Chromium was first proposed as an essential element for normal glucose metabolism in 1959, and was widely accepted as being such by the 1990s.
