Question: how much ceylon cinnamon per day for diabetes?
Answer: The Bottom Line It may be more expensive, but Ceylon cinnamon contains more antioxidants and lower amounts of coumarin, which can potentially cause liver damage. It's probably best not to exceed 0.5–1 grams of Cassia daily, but taking up to 1.2 teaspoons (6 grams) daily of Ceylon cinnamon should be safe.
