What is Ceylon Cinnamon?

Cinnamon's bioactive polyphenols can improve insulin sensitivity and modestly lower fasting and post-meal blood sugar, making it a popular metabolic support. The crucial distinction is the type: most grocery cinnamon is cassia, which is high in coumarin, a compound that can stress the liver at high daily intakes. Ceylon, or true, cinnamon contains only trace coumarin and is the safer choice for daily supplementation. Doses of 0.5 to 1 g of Ceylon cinnamon, or a standardized water-soluble extract, are typical, and it pairs naturally with carbohydrate-containing meals.

WHY IT MATTERS

Ceylon cinnamon supports healthy post-meal blood sugar without the coumarin liver risk of cheaper cassia.
