The purpose of this study was to determine whether cinnamon can lower HbA1c (a long term marker in the blood for blood sugar levels) in patients with type 2 diabetes. The randomized, controlled trial included 109 pediatric, adult and geriatric patients with type 2 diabetes. The patients were randomly assigned to either usual care with management changes by their primary care physician or usual care with management changes plus 1 gram cinnamon capsules daily for 90 days. HbA1c was drawn at baseline and after 90 days. The results revealed that cinnamon lowered HbA1c levels compared with usual care alone. See http://www.raysahelian.com/cinnamon.html
