Most of the cinnamon you find at the grocery store isn't "true" cinnamon. True cinnamon comes from a different, though related, plant species known asCinnamomum verum (aka Cinnamomum zeylanicum), which is native to Sri Lanka (formerly Ceylon). Thus, this distinctive herb is often called Ceylon cinnamon. Other species of cinnamon—the most common being Cinnamomum cassia—share much in common but differ in important ways. True Cinnamon has less volatile oil than cassia cinnamon and contains different levels of key compounds. Our Full Spectrum capsules supply pure, powdered Cinnamomum verum direct from Sri Lanka.
