Chromium is a trace mineral that may enhance the action of insulin, helping cells respond to this hormone and take up glucose from the bloodstream. Given that diabetes mellitus is relatively common in cats (especially overweight, sedentary indoor cats), chromium's potential role in glucose regulation has generated some interest. However, the evidence for chromium supplementation benefits in cats is limited, and it is not considered an essential nutrient at established levels.
Your cat receives trace amounts of chromium from meat-based foods, and no specific daily requirement has been established for cats. Supplementation is not recommended without veterinary guidance, particularly for diabetic cats where insulin management should be directed by your veterinarian.
No specific chromium deficiency syndrome has been clearly established in cats. Theoretical signs would relate to impaired glucose tolerance and insulin resistance.
Chromium from dietary sources is poorly absorbed and excess is excreted by the kidneys. Toxicity from food-based chromium is not a practical concern. Hexavalent chromium (an industrial compound) is toxic, but this form is not found in food.
