You're right there is some research that I've found too that included Type 2 diabetics.
An MD I know recommended that I take some creatine as it helps with GLUT-4 and absorption of glucose the control group had their HbA1c lowered by what looks like a full point! See info below
http://www.ncbi.nlm.nih.gov/pubmed/20881878
RESULTS: Twenty-five subjects were analyzed (CR: n=13; PL: n=12). HbA1c was significantly reduced in the creatine group when compared with the placebo group (CR: PRE=7.4 ± 0.7, POST=6.4 ± 0.4; PL: PRE=7.5 ± 0.6, POST=7.6 ± 0.7; P=0.004; difference=-1.1%, 95% confidence interval=-1.9% to -0.4%).

I have to do some more research on how it helps..
