Brief summary

The purpose of this study is to assess whether Cinnamon bark or water-soluble cinnamon is an effective nutraceutical for the initial treatment of diabetes when compared to standard therapy of Metformin.

Detailed description

We are studying whether or not cinnamon bark or water-soluble cinnamon could be an effective nutraceutical for the initial treatment of diabetes when compared to standard therapy of metformin 1000 mg (extended-release). This study will enroll 309 subjects type 2 diabetics (using American Diabetes Association criteria) on no hypoglycemic medications. Subjects will be randomized into one of three groups, group 1 will receive oral extended-release Metformin 1000mg, group 2 will receive Cinnamon Bark 1000mg, group 3 will receive cinnulin PF 500mg. Subjects will be instructed to take their study pills once a day for 90 days.After 90 days of treatment, each subject will again have hemoglobin A1C, lipid panel, height, weight, blood pressure and waist circumference measured. Analysis described above using intention-to-treat principles for any missing data will be used (we will use the carry-forward method to impute missing data). Subjects will bring in any remaining medication to determine adherence rates to the study protocol.
