Swanson Maximum-Strength Cinnamon Bark delivers outstanding blood sugar support! Our bodies rely on a balance between glucose and insulin in the bloodstream to ensure that the cells get the energy they need to perform their basic biological functions. The flavonoids in cinnamon help insulin work more efficiently to maintain that delicate balance. Each serving of our Cinnamon Bark provides a potent 1.25 g of cinnamon per serving plus a 10:1 cinnamon extract that helps to maintain metabolic balance and support blood sugar health.
