When creatine mono went through its first tests when it first came out, it was tested with coffee and i think even tea. it's not AS effective with coffee as with a high GI carb such as vitagro or dextrose but I would recommend taking creatine mono on a normal diet for 21 days until it's fully absorbed and in your system, then just taking it with coffee while on keto!
Just my 2c
