Don’t use too much. It’s easy to get overambitious with cinnamon, but there are active substances that can hurt you if consumed in excess. Coumarin, as just one example, is a potent blood-thinner and some cinnamon in Europe has a warning label for this reason. Use no more than four grams per day. I use a few dashes in coffee and limit myself to two to three cups of coffee throughout the day.
