I don't find it dissolves or stays in suspension - at the end of the coffee most of the creatine is at the bottom of the mug. Which is a pity as otherwise it would be very efficient, tip it in while the machine makes the cup. Are you stirring it lots or similar?

The creatine I use is finely powdered and it immediately dissolves in very little boiling water. I add it to the second coffee of the day: first one is from the espresso machine for pleasure while waking up, second one is using instant coffee to maintain stable blood caffeine levels. The crema-faking bubbles from the instant espresso powder probably help getting the stuff to dissolve. Then drink it hot and quickly :)
