Effects of chromium supplementation on glycemic control in patients with type 2 diabetes: a systematic review and meta-analysis of randomized controlled trials
What it found
Lowered fasting glucose by ~19 mg/dL and HbA1c by ~0.71 percentage points, with the clearest effect for chromium picolinate; other meta-analyses find no benefit, so results are inconsistent.
