Right after cloves, it is the spice with the highest number of antioxidants. It is also an excellent source of nutrients such as iron, manganese, and calcium. Additionally, it contains fiber and antioxidants that effectively combat free radicals. It is important to note that there are two varieties of cinnamon: Cassia and Ceylon.
