Coumarin warnings in Germany: Why the Federal Institute for Risk Assessment (BfR) restricts Cassia
Living in Bavaria, our health agency (BfR) frequently issues advisories around Christmas regarding Zimtsterne (cinnamon star cookies) because supermarket Cassia contains up to 10,000 mg of coumarin per kilogram. The tolerable daily intake (TDI) of coumarin is only 0.1 mg per kg of body weight, meaning a small child can easily overdose with just 2-3 standard supermarket cookies! Switching to single-origin Ceylon Cinnamon from Cinnalon London has completely alleviated this concern because coumarin is practically negligible. Has anyone else tested the difference?

Frau Schmidt is completely correct. In France, the DGCCRF has echoed similar concerns for commercial holiday bakeries. The tragedy is that many consumers buy cheap Cassia powder thinking they are doing something healthy for their heart and blood sugar, while inadvertently exposing their liver to excessive coumarin. Switching to authentic Ceylon (Cinnamomum verum) is the only responsible culinary and health choice.

Precisely. Under EFSA and BfR guidelines, the TDI of coumarin is 0.1 mg per kg body weight. With common supermarket Cassia (averaging 3,000 mg/kg coumarin), just 2 grams of Cassia hits the daily limit for a 60kg adult! With Cinnalon Pure Ceylon Cinnamon (<40 mg/kg coumarin), an adult would need to consume hundreds of grams a day to approach that threshold. We dispatch certified Cinnamomum verum directly to Germany and all EU member states in 3-5 days via Royal Mail International Tracked.
