Cinnamon is a highly delicious spice.
It has been prized for its medicinal properties for thousands of years.
Modern science has now confirmed what people have known for ages.
Here are 10 health benefits of cinnamon that are supported by scientific research.
1. Cinnamon Is High in a Substance With Powerful Medicinal Properties
Cinnamon is a spice that is made from the inner bark of trees scientifically known as Cinnamomum.
It has been used as an ingredient throughout history, dating back as far as Ancient Egypt. It used to be rare and valuable and was regarded as a gift fit for kings.
These days, cinnamon is cheap, available in every supermarket and found as an ingredient in various foods and recipes.
There are two main types of cinnamon (1Trusted Source):
- Ceylon cinnamon: Also known as “true” cinnamon.
- Cassia cinnamon: The more common variety today and what people generally refer to as “cinnamon.”
Cinnamon is made by cutting the stems of cinnamon trees. The inner bark is then extracted and the woody parts removed.
When it dries, it forms strips that curl into rolls, called cinnamon sticks. These sticks can be ground to form cinnamon powder.
The distinct smell and flavor of cinnamon are due to the oily part, which is very high in the compound cinnamaldehyde (2Trusted Source).
Scientists believe that this compound is responsible for most of cinnamon’s powerful effects on health and metabolism.
Summary
Cinnamon is a popular spice. It’s high in cinnamaldehyde, which is thought to be responsible for most of cinnamon’s health benefits.
2. Cinnamon Is Loaded With Antioxidants
Antioxidants protect your body from oxidative damage caused by free radicals.
Cinnamon is loaded with powerful antioxidants, such as polyphenols (3Trusted Source, 4Trusted Source, 5Trusted Source).
In a study that compared the antioxidant activity of 26 spices, cinnamon wound up as the clear winner, even outranking “superfoods” like garlic and oregano (6Trusted Source).
In fact, it is so powerful that cinnamon can be used as a natural food preservative (7Trusted Source).
Summary
Cinnamon contains large amounts of highly potent polyphenol antioxidants.
3. Cinnamon Has Anti-Inflammatory Properties
Inflammation is incredibly important.
It helps your body fight infections and repair tissue damage.
However, inflammation can become a problem when it’s chronic and directed against your body’s own tissues.
Cinnamon may be useful in this regard. Studies show that this spice and its antioxidants have potent anti-inflammatory properties (8Trusted Source, 9Trusted Source).
Summary
The antioxidants in cinnamon have anti-inflammatory effects, which may help lower your risk of disease.
4. Cinnamon May Cut the Risk of Heart Disease
Cinnamon has been linked to a reduced risk of heart disease, the world’s most common cause of premature death.
In people with type 2 diabetes, 1 gram or about half a teaspoon of cinnamon per day has been shown to have beneficial effects on blood markers.
It reduces levels of total cholesterol, “bad” LDL cholesterol and triglycerides, while “good” HDL cholesterol remains stable (10Trusted Source).
More recently, a big review study concluded that a cinnamon dose of just 120 mg per day can have these effects. In this study, cinnamon also increased “good” HDL cholesterol levels (11Trusted Source).
In animal studies, cinnamon has been shown to reduce blood pressure (3Trusted Source).
When combined, all these factors may drastically cut your risk of heart disease.
Summary
Cinnamon may improve some key risk factors for heart disease, including cholesterol, triglycerides and blood pressure.

5. Cinnamon Can Improve Sensitivity to the Hormone Insulin
Insulin is one of the key hormones that regulate metabolism and energy use.
It’s also essential for transporting blood sugar from your bloodstream to your cells.
The problem is that many people are resistant to the effects of insulin.
This is known as insulin resistance, a hallmark of serious conditions like metabolic syndrome and type 2 diabetes.
The good news is that cinnamon can dramatically reduce insulin resistance, helping this important hormone do its job (12Trusted Source, 13Trusted Source).
By increasing insulin sensitivity, cinnamon can lower blood sugar levels, as discussed in the next chapter.
Summary
Cinnamon has been shown to significantly increase sensitivity to the hormone insulin.
6. Cinnamon Lowers Blood Sugar Levels and Has a Powerful Anti-Diabetic Effect
Cinnamon is well known for its blood-sugar-lowering properties.
Apart from the beneficial effects on insulin resistance, cinnamon can lower blood sugar by several other mechanisms.
First, cinnamon has been shown to decrease the amount of glucose that enters your bloodstream after a meal.
It does this by interfering with numerous digestive enzymes, which slows the breakdown of carbohydrates in your digestive tract (14Trusted Source, 15Trusted Source).
Second, a compound in cinnamon can act on cells by mimicking insulin (16Trusted Source, 17Trusted Source).
This greatly improves glucose uptake by your cells, though it acts much slower than insulin itself.
Numerous human studies have confirmed the anti-diabetic effects of cinnamon, showing that it can lower fasting blood sugar levels by 10–29% (18Trusted Source, 19Trusted Source, 20Trusted Source).
The effective dose is typically 1–6 grams or around 0.5–2 teaspoons of cinnamon per day.

Summary
Cinnamon has been shown to reduce fasting blood sugar levels, having a potent anti-diabetic effect at 1–6 grams or 0.5–2 teaspoons per day.
7. Cinnamon May Have Beneficial Effects on Neurodegenerative Diseases
Neurodegenerative diseases are characterized by progressive loss of the structure or function of brain cells.
Alzheimer’s and Parkinson’s disease are two of the most common types.
Two compounds found in cinnamon appear to inhibit the buildup of a protein called tau in the brain, which is one of the hallmarks of Alzheimer’s disease (21Trusted Source, 22Trusted Source, 23Trusted Source).
In a study in mice with Parkinson’s disease, cinnamon helped protect neurons, normalized neurotransmitter levels and improved motor function (24Trusted Source).
These effects need to be studied further in humans.
Summary
Cinnamon has been shown to lead to various improvements for Alzheimer’s and Parkinson’s disease in animal studies. However, human research is lacking.
8. Cinnamon May Protect Against Cancer
Cancer is a serious disease, characterized by uncontrolled cell growth.
Cinnamon has been widely studied for its potential use in cancer prevention and treatment.
Overall, the evidence is limited to test-tube and animal studies, which suggest that cinnamon extracts may protect against cancer (25Trusted Source, 26Trusted Source, 27Trusted Source, 28Trusted Source, 29Trusted Source).
It acts by reducing the growth of cancer cells and the formation of blood vessels in tumors and appears to be toxic to cancer cells, causing cell death.
A study in mice with colon cancer revealed that cinnamon is a potent activator of detoxifying enzymes in the colon, protecting against further cancer growth (30Trusted Source).
These findings were supported by test-tube experiments, which showed that cinnamon activates protective antioxidant responses in human colon cells (31Trusted Source).
Whether cinnamon has any effect in living, breathing humans needs to be confirmed in controlled studies.

Summary
Animal and test-tube studies indicate that cinnamon may have protective effects against cancer.
9. Cinnamon Helps Fight Bacterial and Fungal Infections
Cinnamaldehyde, one of the main active components of cinnamon, may help fight various kinds of infection.
Cinnamon oil has been shown to effectively treat respiratory tract infections caused by fungi.
It can also inhibit the growth of certain bacteria, including Listeria and Salmonella (32Trusted Source, 33Trusted Source).
However, the evidence is limited and so far cinnamon has not been shown to reduce infections elsewhere in the body.
The antimicrobial effects of cinnamon may also help prevent tooth decay and reduce bad breath (34Trusted Source, 35).
Summary
Cinnamaldehyde has antifungal and antibacterial properties, which may reduce infections and help fight tooth decay and bad breath.
10. Cinnamon May Help Fight the HIV Virus
HIV is a virus that slowly breaks down your immune system, which can eventually lead to AIDS, if untreated.
Cinnamon extracted from Cassia varieties is thought to help fight against HIV-1, the most common strain of the HIV virus in humans (36Trusted Source, 37Trusted Source).
A laboratory study looking at HIV-infected cells found that cinnamon was the most effective treatment of all 69 medicinal plants studied (38Trusted Source).
Human trials are needed to confirm these effects.
Summary
Test-tube studies have shown that cinnamon can help fight HIV-1, the main type of HIV virus in humans.
It Is Better to Use Ceylon (“True” Cinnamon)
Not all cinnamon is created equal.
The Cassia variety contains significant amounts of a compound called coumarin, which is believed to be harmful in large doses.
All cinnamon should have health benefits, but Cassia may cause problems in large doses due to the coumarin content.
Ceylon (“true” cinnamon) is much better in this regard, and studies show that it’s much lower in coumarin than the Cassia variety (39Trusted Source).
Unfortunately, most cinnamon found in supermarkets is the cheaper Cassia variety.
You may be able to find Ceylon in some health food stores, and there is a good selection on Amazon.
The Bottom Line
At the end of the day, cinnamon is one of the most delicious and healthiest spices on the planet.
It can lower blood sugar levels, reduce heart disease risk factors and has a plethora of other impressive health benefits.
Just make sure to get Ceylon cinnamon or stick to small doses if you’re using the Cassia variety.
