Natural Blood Sugar Control, Digestive Help and Immune Support

1200 mg Non-GMO Ceylon Cinnamon In Vegan Capsules

Not all cinnamon is equal. The variety (Cassia Cinnamon) that you commonly find in the spice section of the supermarket is high in coumarin, a chemical that enhances flavor.1,2

This might be good if you’re baking a batch of Grandma’s crazy good cinnamon buns while you wait out a Canadian blizzard (ask us how we know). But coumarin has a big downside: it can cause liver damage. 3 Importantly, it doesn’t take much of Cassia Cinnamon to exceed the upper limits of safe intake of coumarin. Ingesting just one to two teaspoons of Cassia Cinnamon could be toxic for some people.4

By contrast, Ceylon Cinnamon has 250 times less coumarin than the Cassia variety 2, making it a better choice as a nutritional supplement. You get the concentrated health benefits of this super spice without taking in potentially dangerous levels of coumarin.

Cinnamon has been used medicinally since Ancient Egypt. Recent studies 5 suggest that it can offer an impressive range of health benefits. It appears to help control blood sugar, 6 support digestion, 7 lower cholesterol 8 and improve immune function.9 When taken with carbohydrates, cinnamon has been shown to slow the rate that glucose enters into the bloodstream.10

Health Benefits of Ceylon Cinnamon

Regulate Blood Sugar

Research suggests that Ceylon Cinnamon helps regulate blood sugar.6 When taken with a high carbohydrate meal, it appears to aid with digestion, decrease the influx of glucose and improve insulin response.10

Anti-bacterial and Anti-fungal

Studies show that Ceylon Cinnamon can help stop the growth of bacteria and fungus, including candida yeast.13,14

Lower Cholesterol

Studies have shown that ingestion of Ceylon Cinnamon can reduce LDL cholesterol, Triglycerides and total cholesterol levels.8


Studies have shown15-17 that cinnamon extracts downregulate the inflammatory proteins produced by multiple immune cells. Other research suggests that it may also ease muscle soreness caused by exercise.18

Support Healthy Immune Function

Ceylon Cinnamon has been shown to be rich in antioxidants,11,12 which play an essential role in strengthening the immune system.

Improve Cognitive Function

Preliminary animal studies have shown cinnamon has the potential to improve working memory,19 memory performance20 and it may have neuroprotective properties.21, 22

Your Questions, Our Answers

See the most popular questions asked about Ceylon Cinnamon.

Should I take this on an empty stomach or with a meal?

To receive maximum benefit, we recommend taking it with your highest carbohydrate meal. The Ceylon Cinnamon has been shown to slow the absorption of carbohydrates. This not only helps with digestion, but it helps control blood sugar.

Can’t I just use more cinnamon in my cooking?

You could, but it would be difficult to get the same benefits that taking a supplement offers. First, you’d need to be sure to use Ceylon Cinnamon. The cinnamon that is most commonly available for cooking is Cassia Cinnamon, which is high in coumarin—a toxin.

The daily recommended dose of Ceylon Cinnamon to help with blood sugar control is one to six grams. That’s a lot of cinnamon to work into your cooking every day! We find it’s much easier to get the beneficial dose through a supplement.

What is rice flour doing in Nested Naturals Ceylon Cinnamon?

Rice flour helps flow the supplement ingredients into the capsule. Miniscule amounts are used during the manufacturing process. You’ll find it listed under “Other Ingredients” on our label because we believe that you deserve to know everything that goes into our supplements and your body.

What is vegetable cellulose and what is it doing in Nested Naturals Ceylon Cinnamon?

We use vegetable cellulose to make our gel-caps. We’re proud to say that our capsules are vegan and don’t include any animal parts.
