Can cinnamon lower blood glucose levels?

Early studies suggested that cinnamon might be effective for lowering blood sugar (glucose) levels. Recent studies show conflicting results regarding the effect of cinnamon on blood sugar levels. There is also some concern that large amounts of cinnamon may result in liver damage. More evidence-based research is needed to rate the effectiveness of cinnamon in lowering blood sugar. Using cinnamon in amounts commonly found in foods is generally considered safe.

There isn't any hard evidence that cinnamon can significantly lower blood sugar levels, and preliminary studies on cinnamon for treatment of diabetes have had mixed results. However, cinnamon is not harmful and many people with diabetes say it helps keep their blood sugar levels more stable. Cinnamon can be used to flavor many foods such as sweet potatoes and even cereal.
