Chromium for Insulin Resistance

B Good Evidence At least one randomized trial supports this, with mostly consistent results.

Meta-analysis of 25 RCTs found significant improvements in fasting glucose (1.16 mmol/L) in type 2 diabetics. Chromium enhances insulin receptor substrate phosphorylation. The ADA notes insufficient evidence for routine recommendation.
