Apparently the higher the level of adiponectin the lower the chance of diabetes.  It does not appear to help existing diabetes.

As a side note my husband died from diabetes and if you are diabetic you should get your medical advice from a Physician and should not attempt "self help."
Hopefully you are simply asking a question in order to get information.
