Supports cardiovascular health and blood sugar metabolism Provides metabolic support Manages blood sugar levels Full spectrum Cinnamomum verum Not just for your latte or oatmeal, cinnamon can help the body use insulin more effectively and may support healthy blood sugar levels already within a normal range. Swanson Full Spectrum True Cinnamon capsules supply pure, powdered Cinnamomum verum direct from Sri Lanka. 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 as Cinnamomum 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.
