Ceylon cinnamon is also rich in the mineral manganese. This mineral helps your body manage the enzymes that produce hormones and help repair your bones. Manganese also works as an antioxidant as part of the enzyme manganese superoxide dismutase, protecting your body from free radicals. All types of cinnamon contain a compound known as coumarin, which is known to be harmful in large amounts. Ceylon cinnamon has much less coumarin than cassia cinnamon. If you are concerned about coumarin, Ceylon cinnamon is a safer option for your spice rack.
