It have to be “Ceylon” cinnamon to stabilize your blood sugar level. If you are taking 1 tsp-1tbsp in the morning with smoothie, for example, this cinnamon will stabilize the blood sugar level all day long even taken with a banana. I do recommend “GREEN” banana which is RE stands for “Resistant Starch”. It will stabilize the blood sugar level but when it ripen (yellow with black dots on the skin), the chemical composition on the banana changes from RE to simple sugar which you might avoid eating that every single day, especially in the morning!
