Naturevibe Botanicals Ceylon Cinnamon Powder 2.2 kg, Ground | Gluten-Free, Keto Friendly & Non-GMO

I have had my cinnamon for about a week now. i was disappointed in the grind. it is grainy and does not mix into my coffee. what can i do?

Seller: the image looks like cassia cinnamon sticks, not ceylon. can you verify that this product is ceylon cinnamon, and not cassia cinnamon?

How much coumarin does it have? I want to take 2 teaspoons a day and don’t want to get sick

Is there certificate of analysis available for this product? A few reviews suggest that this might not be Ceylon, but rather Cassia.
