Doctors said that there are few human studies on the effects of cinnamon on blood sugar, but that earlier animal studies suggest cinnamon may lower blood sugar by slowing absorption through the intestine, or stimulating cells to absorb sugar from the bloodstream.

Researchers reviewed six cinnamon studies involving 435 men and women who took 1 to 6 grams of cinnamon per day for 40 to 120 days.

On average, over the various study periods, long-term blood sugar marker (HbA1C) levels dropped 0.1 percent, and fasting blood sugar levels dropped 0.84 micromoles per liter of blood. HbA1C, glycated hemoglobin, is a lab test that shows the average amount of sugar in blood over 3 months.

Doctors think that cinnamon may help diabetics control blood sugar and urge more study.
