Overview

Ceylon cinnamon, or Cinnamomum verum, is a type of cinnamon native to Sri Lanka. It is distinct from the more common Cassia cinnamon and is favored for its milder, more complex flavor and significantly lower levels of coumarin, a compound that can be harmful to the liver in high doses. It is used to support healthy blood sugar metabolism.

Key Benefits

Improves Insulin Sensitivity

Ceylon cinnamon can mimic insulin and increase glucose uptake by cells, helping to lower blood sugar.

Potent Antioxidant

Rich in polyphenols, it helps protect the body from oxidative damage caused by free radicals.

Low Coumarin Content

Much safer for long-term use than Cassia cinnamon, which contains high levels of potentially liver-toxic coumarin.

Anti-Inflammatory Properties

The antioxidants in Ceylon cinnamon also have anti-inflammatory effects.

Dosage & How to Take
