Diabetes is a disease characterized by abnormally high blood sugar.
If poorly controlled, it can lead to complications like heart disease, kidney disease and nerve damage ( 1 ).
Treatment often includes medications and insulin injections, but many people are also interested in
foods that can help lower blood sugar .
One such example is cinnamon, a commonly used spice that’s added to sweet and savory dishes around the world.
It provides many health benefits , including the ability to lower blood sugar and help manage diabetes.
This article tells you everything you need to know about cinnamon and its effects on blood sugar control and diabetes.

What Is Cinnamon?

Cinnamon is an aromatic spice derived from the bark of several species of Cinnamomum trees.
While you may associate cinnamon with rolls or breakfast cereals, it has actually been used for thousands of years in traditional medicine and food preservation.
To obtain cinnamon, the inner bark of Cinnamomum trees must be removed.
The bark then undergoes a drying process that causes it to curl up and yield cinnamon sticks, or quills, which can be further processed into powdered cinnamon.
Several different varieties of cinnamon are sold in the US, and they are typically categorized by two different types:
Ceylon: Also called “true cinnamon,” it’s the most expensive type.
Cassia: Less expensive and found in most food products containing cinnamon.
While both types are sold as cinnamon, there are important differences between the two, which will be discussed later in this article.
SUMMARY:
Cinnamon is made from the dried bark of
Cinnamomum trees and is generally categorized into two varieties.

It Contains Antioxidants That Provide Many Health Benefits

quick glance at cinnamon’s nutrition facts may not lead you to believe that it’s a superfood ( 2 ).
But while it doesn’t contain a lot of vitamins or minerals, it does contain large amounts of antioxidants, which give it its health benefits.
In fact, one group of scientists compared the antioxidant content of 26 different herbs and spices and concluded that cinnamon had the second highest amount of antioxidants among them (after cloves) ( 3 ).
Antioxidants are important because they help the body reduce oxidative stress, a type of damage to cells, which is caused by free radicals.
One study showed that consuming 500 mg of cinnamon extract daily for 12 weeks decreased a marker of oxidative stress by 14% in adults with prediabetes ( 4 ).
This is significant, since oxidative stress has been implicated in the development of nearly every chronic disease, including type 2 diabetes ( 5 ).
SUMMARY:
Cinnamon does not contain many vitamins or minerals, but it is loaded with antioxidants that decrease oxidative stress. This may potentially protect against diabetes.

It Can Imitate Insulin and Increase Insulin Sensitivity

In those with diabetes, either the pancreas cannot produce enough insulin or cells do not respond to insulin properly, leading to high blood sugar levels.
Cinnamon may help lower blood sugar and fight diabetes by imitating the effects of insulin and increasing glucose transport into cells ( 6 ).
It can also help lower blood sugar by increasing insulin sensitivity, making insulin more efficient at moving glucose into cells.
One study of seven men showed taking cinnamon increased insulin sensitivity immediately after consumption, with the effect lasting at least 12 hours ( 7 ).
In another study, eight men also demonstrated increases in insulin sensitivity following two weeks of supplementing with cinnamon ( 8 ).
SUMMARY:
Cinnamon can lower blood sugar by acting like insulin and increasing insulin’s ability to move blood sugar into cells

It Lowers Fasting Blood Sugar and May Decrease Hemoglobin A1c

Several controlled studies have demonstrated that cinnamon is excellent at reducing fasting blood sugar.
One review of 543 people with type 2 diabetes found taking it was associated with an average decrease of over 24 mg/dL (1.33 mmol/L) ( 9 ).
While these study results are pretty clear, studies investigating its effects on hemoglobin A1c, a measure of long-term blood sugar control, have yielded conflicting results.
Some studies report significant decreases in hemoglobin A1c, while others report no effect ( 9 , 10 ,
11 , 12 ).
The conflicting results may be partially explained by differences in the amount of cinnamon given and prior blood sugar control of participants ( 9 , 13 ).
SUMMARY:
Cinnamon shows promise in lowering blood sugar. However, its effects on hemoglobin A1c are less clear.

It Lowers Blood Sugars After Meals

Depending on the size of the meal and how many carbs it contains, blood sugar levels can rise pretty dramatically after you eat.
These blood sugar fluctuations can increase levels of oxidative stress and inflammation, which tend to do a lot of damage to your body’s cells and put you at risk of chronic disease ( 14 , 15 ).
Cinnamon can help keep these blood sugar spikes after meals in check. Some researchers say it does this by slowing down the rate at which food empties out of your stomach.
One study found that consuming 1.2 teaspoons (6 grams) of cinnamon with a serving of rice pudding led to slower stomach emptying and lower blood sugar elevations then eating rice pudding without it ( 16 ).
Other studies suggest that it may lower blood sugar following meals by blocking digestive enzymes that break down carbs in the small intestine ( 17 , 18 ).
SUMMARY:
Cinnamon can lower blood sugar following meals, possibly by slowing stomach emptying and blocking digestive enzymes.

It May Lower the Risk of Common Diabetes Complications

Depending on the size of the meal and how many carbs it contains, blood sugar levels can rise pretty dramatically after you eat.
These blood sugar fluctuations can increase levels of oxidative stress and inflammation, which tend to do a lot of damage to your body’s cells and put you at risk of chronic disease ( 14 , 15 ).

SUMMARY:
Cinnamon can lower blood sugar following meals, possibly by slowing stomach emptying and blocking digestive enzymes.

It May Lower the Risk of Common Diabetes Complications

This spice does more than lower fasting blood sugar and decrease blood sugar spikes following meals.
It may also lower the risk of common diabetes complications.
People with diabetes have twice the risk of heart disease as people without it. Cinnamon may help lower this risk by improving established risk factors for heart disease ( 19 ).
A review of controlled studies in people with type 2 diabetes found that taking cinnamon was associated with an average decrease in “bad” LDL cholesterol of 9.4 mg/dL (0.24 mmol/L) and a decrease in triglycerides of 29.6 mg/dL (0.33 mmol/L) ( 9 ).
It also reported an average 1.7 mg/dL (0.044 mmol/L) increase in “good” HDL cholesterol ( 9 ).
Furthermore, another study found that supplementing with two grams of cinnamon for 12 weeks significantly lowered both systolic and diastolic blood pressure ( 11 ).
Interestingly, diabetes has also been increasingly implicated in the development of Alzheimer’s disease and other dementias, with many people now referring to Alzheimer’s disease as “type 3 diabetes” ( 20 ).
Studies suggest that cinnamon extract may decrease the ability of two proteins — beta-amyloid and tau — to form plaques and tangles, which are routinely linked to the development of Alzheimer’s disease ( 21 , 22 ).
However, this research has only been completed in test tubes and animals. Further studies in humans are needed to confirm these findings.
SUMMARY:
Cinnamon may help lower the risk of diseases related to diabetes, such as heart disease and Alzheimer’s disease.
