Abstract

Systematic review and meta-analysis of 28 randomized controlled trials (3054 patients with type 2 diabetes): cinnamon supplementation significantly reduced fasting blood glucose (-15.26 mg/dL), postprandial glucose (-39.22 mg/dL), HbA1c (-0.56) and HOMA-IR versus control, especially in capsule form at doses of 2 g/day or less. Evidence that cinnamon lowers blood glucose and may add to antidiabetic medicines.
