Cinnamon supplementation in horses can have certain benefits, but there is no clear directive about if and how much cinnamon to give horses and in what form.
This is stated on the website of Kentucky Equine Research.
“Cinnamon supplementation provides yet another example of a traditional herbal medicine making a comeback to benefit modern medical patients,” said Kathleen Crandell, Ph.D., a nutritionist for Kentucky Equine Research (KER). Research from Ranasingh et al (2013) and Branchea et al (2015) revealed that the potential benefits associated with cinnamon can be found in their antioxidant properties, antidiabetic effects and antimicrobial activity.

At the same time, no controlled research on the benefits of cinnamon to horses, other than insulin sensitivity, has been conducted. Because of this, there is no clear directive about if and how much cinnamon to give horses and in what form.
Crandell adds, “Before adding, changing, or modifying any aspect of your horse’s diet, understand that important interactions between herbs and ingredients or nutrients exist. Always contact a veterinarian or (KER) nutritionist for a consultation on this.
