Studies suggest that cinnamon may provide support for maintaining blood sugar levels already within the normal range. This discovery was found quite by accident when researchers were studying why people who ate apple pie had lower blood sugar levels. Turns out the active ingredient in cinnamon, called MHCP, works with the blood sugar in your system. This doesn't mean you should eat apple pie every day. However, it may mean high quality cinnamon supplements could be a healthy choice for you. An added benefit? Cinnamon can soothe your digestion, too.
