Doubledogdair, I have not found ceylon in a stick only in a powdered form. If it does not say Ceylon then it most likely isn't Ceylon and is Cassia cinnamon. I buy it in a one pound container and it has lasted almost a whole year. This is where I get my Ceylon cinnamon.
I take cinnamon everyday. I add it to my blast and to my hot tea or chocolates. Try using 1/2 tsp to start and see how you like it. Ceylon cinnamon isn't as strong as cassia cinnamon. There are no harmful effects from Ceylon cinnamon where there are from Cassia cinnamon.
I hope this helps, Healthy wishes, Wally Bishop C.N.C.
