Trivalent chromium (Cr3+) is an essential nutrient that enhances insulin sensitivity and glucose tolerance by acting as a cofactor for chromodulin, which potentiates insulin binding to cell surface receptors.

Chromium is an essential trace mineral that helps insulin work more efficiently, particularly when you are under physical, metabolic, or nutritional stress. While healthy people with balanced diets likely get enough, those under stress or with insulin resistance may benefit. Focus on organic forms of chromium found in food or high-quality supplements, as inorganic forms are poorly absorbed. Do not expect dramatic fat loss or muscle gain from chromium alone in healthy, unstressed individuals.

Trivalent chromium is essential to normal carbohydrate, lipid and protein metabolism. Chromium is biologically active as part of an oligopeptide – chromodulin – potentiating the effect of insulin by facilitating insulin binding to receptors at the cell surface.

Why this rating

The paper is a review citing animal studies and some human trials, but notes ambiguous results in humans and low bioavailability of inorganic forms.
