 Which Cinnamon Has the Lowest Levels of Coumarin?

 

Coumarin is substance that can cause liver damage or complete failure. Only Ceylon Cinnamon has low levels of Coumarin, while all other varieties of Cinnamon have high levels of Coumarin. At one stage the German government banned Cassia type Cinnamon. But take a closer look at this university of Mississippi study which shows the high levels of Coumarin in all other type of Cinnamon, except Ceylon Cinnamon. So if you are taking Cinnamon for health reasons, then you must and should switch to Ceylon Cinnamon. The European Food Safety Authority (EFSA) established a tolerable daily intake (TDI) of 0.1 mg/kg body weight.
