I have heard that cinnamon is good for lowering your blood sugar. How does it work?
There are two types of cinnamon: cassia and Ceylon. Cassia cinnamon is the type most commonly used in the U.S. and also is the type that researchers have studied for its possible effects on blood glucose and diabetes control. In several studies of people with type 2 diabetes, cinnamon has lowered blood glucose levels by decreasing insulin resistance. In one particular study, subjects who consumed half of a teaspoon of ground cinnamon per day lowered their blood glucose, on average, by 24 percent. However, other studies indicate that cinnamon has no effect on blood glucose. Cinnamon is safe to use unless you have liver disease. It may also increase the risk of low blood glucose if you take it in conjunction with diabetes medicines like insulin or sulfonylureas (e.g., glipizide, glyburide, glimepiride). Sprinkling some cinnamon on your morning oatmeal or stirring some into yogurt is certainly fine, but if you’re interested in trying it as a supplement, be sure to first discuss it with your healthcare provider.
