Cinnamon is a spice that has been used since ancient times for medicinal purposes. Recently, cinnamon has become a hot topic in diabetes research with conflicting results. The studies have been based on the idea that cinnamon may help to lower blood sugar.

How Cinnamon Might Lower Blood Sugar

Studies showing cinnamon as an effective diabetic treatment have proposed that cinnamon may have an insulin-like effect on cells — triggering cells to take glucose out of the blood — or that cinnamon may cause an increase in the activity of the transporter proteins that move glucose out of the bloodstream and into cells.

What the Research Says About Cinnamon and Blood Sugar

In the 2000s, several studies showed conflicting results, with some studies pointing to a hypoglycemic (blood sugar lowering) effect of cinnamon and others showing no significant effect. But more recent research suggests that cinnamon may indeed help to lower blood sugar. A 2013 review of 10 randomized control trials (the strongest kind of study for nutrition research) suggests that ingesting cinnamon does, in fact, lower fasting blood sugars, as well as total cholesterol.

How to Add Cinnamon to Your Diet

In the randomized controlled trials, people were given between 120 mg/day to 6 g/day for 4 to 18 weeks. That’s the equivalent of between a small fraction of a teaspoon to two teaspoons per day. Adding a small amount of cinnamon to your daily diet–by sprinkling it on oatmeal, or using it to spice up a Mexican chili–can’t hurt and may help.

But as with any supplement, check with your healthcare professional before taking cinnamon in larger doses.

Things to Consider Before Taking Cinnamon for Diabetes

As with all dietary supplements, it should be noted that supplements are not regulated by the FDA, leaving the door open to manufacturing risks.

In addition, cinnamon may increase the risk of liver problems and reduce the blood’s ability to clot. Because cinnamon may lower blood-sugar levels, caution should be exercised when combining it with other common diabetic medications and/or supplements that may also lower sugar levels. Some of these supplements include: alpha lipoic acid, bitter melon, chromium, devil’s claw, fenugreek, garlic, horse chestnut, Panax, Siberian ginseng, and psyllium.

Though some studies have shown cinnamon can improve glucose and lipid levels in type 2 diabetes, other studies have not shown cinnamon to improve glycemic control. Since the data regarding cinnamon’s efficacy in reducing glucose levels is inconsistent, the American Diabetic Association does not endorse the use of cinnamon as a therapy for diabetes at this time. Your first approach in managing diabetes should be to follow your diabetes meal plan, staying physical activity and taking any prescribed medications.
