- Cinnamon’s antioxidants may protect cells, lower inflammation and reduce chronic disease risk.
- Around a teaspoon a day may help control blood sugar, boost insulin sensitivity and support heart health.
- Be mindful about consuming large doses or cinnamon supplements, as they can interact with medications and have negative health effects.
Cinnamon isn’t just a cozy spice for your latte or oatmeal—it’s one of the oldest known spices, used for centuries for both flavor and potential health benefits. And according to dietitians, modern research is beginning to confirm what ancient traditions may have believed. “Cinnamon offers several health benefits thanks to its high antioxidant content and anti-inflammatory properties,” says Samantha DeVito, M.S., RD, CDN. Keep reading to learn why cinnamon is so good for you, plus the best ways to add it to your routine.
Why We Love Cinnamon
It’s Rich in Antioxidants
“Cinnamon is full of antioxidants, particularly polyphenols like cinnamic acid and cinnamaldehyde,” says Avery Zenker, RD, M.A.N. Antioxidants help the body neutralize oxidative stress, a process that can otherwise damage cells and contribute to chronic inflammation. When the body is exposed to inflammation over extended periods, the risk of metabolic diseases increases.
“Cinnamon’s abundant antioxidant profile could help protect your cells from damage, slow aging-related processes and may reduce the risk of chronic diseases,” Zenker adds.
It May Support Healthy Blood Sugar
Cinnamon has been widely studied for its potential role in regulating blood sugar levels. Its plant compounds may mimic insulin, making it easier for the body to move glucose into cells and lowering blood sugar levels.
Research has tested a range of cinnamon doses to see if more is better, but benefits don’t seem to depend on the amount consumed. “Even as little as a teaspoon (about 2 grams) per day could improve blood sugar regulation in some individuals,” says Zenker. “It has also been shown to improve insulin sensitivity and reduce post-meal blood sugar spikes, which is particularly relevant for people with prediabetes or type 2 diabetes,” DeVito tells EatingWell.
“Whether consumed in foods, teas or supplements, cinnamon may help improve blood sugar control in people with and without diabetes,” says Sheri Gaw, RD, CDCES.
It Could Benefit Heart Health
According to both Zenker and DeVito, cinnamon may also play a supportive role in maintaining healthy cholesterol and triglyceride levels—two key markers of cardiovascular risk. Some recent studies suggest that regular cinnamon intake is linked to lower total and LDL (often called “bad”) cholesterol levels, reductions in triglycerides and improvements in HDL cholesterol—the “good” cholesterol that helps protect your arteries.
“Cinnamon may also have modest benefits for blood pressure, though findings are mixed,” adds Zenker. One study found that consuming cinnamon consistently for eight weeks led to lower blood pressure.
While cinnamon alone won’t replace other heart-healthy habits or doctor-recommended treatments, adding it regularly to meals is one simple way to give your cardiovascular system an extra boost.
It Might Help Reduce Inflammation-Related Disorders
Many health conditions are influenced by chronic inflammation, and the plant compounds in cinnamon may help calm inflammatory pathways. These benefits could be particularly beneficial for individuals managing arthritis, heart disease and type 2 diabetes.
“Cinnamon intake has been associated with reduced systemic inflammation, including lower levels of C-reactive protein (CRP), a marker of inflammation,” says Zenker. Further research is needed to investigate the long-term effects. Still, adding cinnamon to meals may offer gentle support against the kind of ongoing inflammation that can worsen symptoms of chronic disease.
Nutrition Information
Cinnamon is usually consumed in small amounts, so it doesn’t provide a significant source of calories or major nutrients. Here’s the breakdown for 1 teaspoon (2.6 grams) of ground cinnamon:
- Calories: 6
- Carbohydrates: 2g
- Dietary fiber: 1g
- Total sugar: 0g
- Added sugar: 0g
- Protein: 0g
- Total fat: 0g
- Saturated fat: 0g
- Cholesterol: 0mg
- Sodium: 0mg
Is Cinnamon Safe for Everyone?
For most people, cinnamon is generally safe in the small amounts typically used for flavoring food. Studies on potential health benefits have examined doses of about 1 to 6 grams per day—roughly ½ teaspoon to 2 teaspoons of ground cinnamon.
Dietitians say that the type of cinnamon you choose may make a difference. Cassia cinnamon, the variety most often sold in grocery stores, contains higher levels of coumarin, a natural compound that can be harmful to the liver in large amounts. “Excessive coumarin intake can lead to liver damage, and symptoms like dizziness, diarrhea and vomiting,” says Zenker. Ceylon cinnamon—sometimes called “true cinnamon”—has very little coumarin and is considered a safer choice if you use cinnamon regularly.
It’s also important to be cautious with supplements or very large amounts. “Large doses of cinnamon, either in the powder or supplement form, may interact with some medications (blood thinners, antibiotic and diabetes or heart medications) or cause mouth irritation or liver toxicity,” says Gaw.
Ways to Enjoy Cinnamon
Cinnamon is one of the easiest spices to incorporate into your diet. Here are some dietitian-approved ideas:
- Stir into oatmeal, yogurt, smoothies or coffee for a delicious addition.
- Sprinkle on roasted sweet potatoes, squash or carrots.
- Mix into homemade granola, energy bites or baked goods for a cozy treat.
- Add a dash to chili, curries or stews for extra depth.
- Pair with fruit like apples, pears, peaches or bananas for a natural flavor boost.
Our Expert Take
Cinnamon is a staple in the spice rack with several potential health benefits. Its antioxidants and anti-inflammatory compounds could support blood sugar control, heart health and even help ease the effects of chronic inflammation. Still, experts emphasize that cinnamon works best as part of an overall balanced diet—it’s not a substitute for medical care or other healthy lifestyle habits.
If you consume it frequently, keep portions moderate and be aware of potential medication interactions. Ask a health care provider if you’re unsure. Otherwise, sprinkling cinnamon into your meals is an easy, flavorful way to add a bit of extra wellness to your routine.
