It's a pantry staple seen in homes throughout the country, but is it safe for your to eat?

What Types of Cinnamon are Safe for Dogs?

Cinnamon is a spice that is found in almost every American kitchen. It may be used in both sweet and savory recipes, including sweets and breakfast meals. Cinnamon is made from the Cinnamomum tree's bark.

Cinnamon comes in two varieties that are widely available in marketplaces across the world. Ceylon cinnamon, sometimes known as 'genuine' cinnamon or 'Chinese' cinnamon, and Cassia cinnamon are two types of cinnamon.

Ceylon cinnamon originates from the C. verum tree, which grows across Sri Lanka. Cassia cinnamon comes from the C. cassia tree, which grows throughout China. Cassia cinnamon is darker than ceylon cinnamon, having thicker sticks and a coarser texture. It's also less costly than ceylon cinnamon, which is the most widely used kind across the world, especially in the United States. Unless you go to a high-end specialized spice store, the cinnamon sticks and ground cinnamon in your cupboard and at your local grocery store are almost certainly cassia cinnamon.

Potential Health Benefits

Cinnamon is thought to have many health benefits. Cinnamon is a good source of antioxidants which have anti-inflammatory benefits.

It's being researched for its possible role in preventing Alzheimer's disease by inhibiting tau protein build-up in the brain. Cinnamon can also help diabetics by lowering blood sugar levels and raising insulin sensitivity, both of which are beneficial to them. Cinnamon's antibacterial and antifungal qualities are even the subject of research!

With all of these wonderful advancements in human health, it's understandable that well-intentioned dog owners would want to feed their dog cinnamon in the hopes of experiencing similar outcomes. However, our understanding of cinnamon's usage in integrative human health is still developing, and there isn't as much investigation into whether similar applications in human medicine also apply to our canine friends.

Potential Health Concerns

It's worth noting that coumarin, a naturally occurring plant chemical, can be extracted from both cassia and ceylon cinnamon. It has a pleasant, aromatic aroma and is commonly used in perfumes and cosmetics, but it is also utilized as a precursor to anticoagulant drugs like warfarin and Coumadin.


Excessive coumarin use can be harmful to the liver and kidneys. The top limits of a daily allowance in a person's diet have been determined by study. Unfortunately, no data exists on the amount of daily coumarin that might induce liver or kidney damage in dogs. Cassia cinnamon contains a higher concentration of coumarin than ceylon cinnamon, with 1% coumarin compared to 0.004% in ceylon cinnamon. While both kinds contain minor amounts of coumarin, ceylon cinnamon is substantially safer in terms of coumarin toxicity.

Though cinnamon is legally a healthy food for dogs to eat, it is not without risk, and the applications and advantages of include it in your dog's regular diet are not yet completely understood. If you wish to add cinnamon to your dog's diet, see your veterinarian first before adding it to his food or using cinnamon oil in your essential oil diffuser.
