SECONDARY outcome

Timeframe: Baseline and 6 months

The changes in insulin resistance parameters in overweight patients with PCOS between baseline and after 6 months of daily cinnamon compared to the corresponding change in patients receiving 6 months of placebo. Higher values of insulin resistance represent a worse outcome. A higher value Homeostasis Model of Insulin Resistance indicates more insulin resistance so higher values are worse outcomes (a score of \>2 is considered healthy for adults with scores \>5 being considered severe insulin resistance). For the Quant. Insulin Sensitivity Check Index, a lower value indicates more insulin resistance so lower values are worse outcomes (values can range from .45, which is considered normal in health individuals and .30, which is characteristic of diabetes).

SECONDARY outcome

Timeframe: Baseline and 6 Months - fasting bloods, followed by glucose tolerance test with draws at 30, 60, and 120 minutes post glucose ingestion

Change in Glucose Response - area under the curve (AUC), trapezoidal method - in overweight patients with PCOS between baseline and after 6 months of daily cinnamon compared to the corresponding change in patient receiving 6 months of placebo. Fasting blood samples were drawn followed by a 2 hour glucose tolerance test with blood draws at 30, 60, and 120min post glucose ingestion.
