Cinnamon is popular spice worldwide. It exerts numerous biological effects on the body.
Cinnamon is frequently treated as an anti-diabetic compound, since it reduces the rate at which glucose enters the body. Not only does it help diabetics avoid blood sugar spikes, but it also improves glucose use in the cell itself.
Over time, cinnamon can reduce fasting blood glucose, and potentially cholesterol levels as well.
Cinnamon does not need to be purchased specifically as a supplement, and can be found in grocery stores. It does contain a liver toxin called coumarin, which can be harmful in high doses. Making cinnamon tea can reduce the risk of coumarin poisoning, since the toxin is left behind in the leftover sediment. Ceylon cinnamon, which is dervied from a different plant species, has lower levels of coumarin, which makes it a better supplement option.
