True Ceylon Cinnamon, not Cassia
Last updated: May 2026
This is the single most important distinction in the cinnamon aisle. Most supermarket cinnamon worldwide is Cassia, which is high in coumarin and not safe at clinical doses. Ancient Nutra Ceylon Cinnamon is true Cinnamomum verum, low in coumarin, and the form clinical research on blood-sugar and cardiovascular markers actually uses. Each capsule contains pure ground Ceylon Cinnamon bark from Sri Lankan farms.
What it traditionally supports
Ceylon Cinnamon is traditionally used for blood-sugar support and cardiovascular wellness. Recent clinical studies use doses of 1 to 3 grams per day for measurable effects on fasting glucose and HbA1c markers.
How to take it
Take 1 to 2 capsules with the largest carbohydrate meal of the day. Some users split the dose between breakfast and dinner.
Who it is for
- Adults focused on blood-sugar balance alongside medical care.
- People who want a daily heart-supportive routine.
- Anyone replacing supermarket Cassia cinnamon with the safer Ceylon variety.
Frequently asked questions

How much per day?
Clinical studies typically use 1 to 3 grams per day, which is 2 to 4 of our capsules.
Can I take this with metformin or insulin?
Yes, but speak with your doctor first, as cinnamon can amplify their blood-sugar effect.
