In one study participants took between 1 and 6 grams of cinnamon for 40 days, causing the participants' blood sugar levels to decrease by 24 percent, reports WebMD.
Prevention Magazine suggests cooking with the spice to lower blood sugar levels, and NPR claims that cinnamon can be taken in capsule form.
Although some research has shown positive results linking cinnamon to lower blood sugar levels, high doses of Cassia cinnamon, the most common type of cinnamon, have also been shown to cause problems in certain people due to its coumarin content, claims NPR. To combat this problem, the European Food Safety Authority recommends no more than 1 teaspoon of cinnamon daily for those who are sensitive to coumarin.
However, there is another type of cinnamon, Ceylon cinnamon, that may help reduce blood sugar levels without the harmful effects of coumarin, claims NPR. As of 2015, though, the majority of the testing done on cinnamon and its effect on blood pressure has been performed using Cassia cinnamon, according to WebMD.Learn more about Herbs & Spices
