Is one tablespoon of cinnamon daily to much?

One tablespoon of cinnamon daily can be excessive, especially if it contains cassia cinnamon, which has higher levels of coumarin—a compound that can be harmful in large amounts. Consuming it in moderation is generally safe for most people, but it's best to consult with a healthcare professional if you plan to make it a daily habit. Ceylon cinnamon is a safer alternative due to its lower coumarin content.
