Chrom

Mineral Evidence: moderate

Overview

Chromium is an essential ultratrace mineral proposed to potentiate insulin action via chromodulin. Adequate intake: 20–35 mcg/day; no upper limit established. Evidence for blood glucose lowering is contested: a 2019 meta-analysis of 58 trials found only slight effects; the American Diabetes Association does not recommend routine supplementation. FDA permits only a qualified health claim that the relationship to diabetes risk is "highly uncertain." Caution with insulin, metformin (hypoglycemia risk), and levothyroxine (reduced absorption).
