Short answer
Yes. Creatine and caffeine work fine together. You can mix the stick directly into your morning coffee, or take it alongside.
How to do it
Pour one stick into your coffee (hot or iced) and stir.
Or dissolve the stick in 250–300 ml of water and drink it before or with your coffee.
Both work equally well.
Notes
The old "caffeine cancels creatine" claim comes from one small 1990s study that has since been contradicted by newer research.
Many women find taking the stick with their morning coffee makes it easier to remember — the habit piggybacks on an existing one.
