Cinnamon extract can improve your body composition and partially reverse the metabolic syndrome.  Subjects with prediabetes and the metabolic syndrome experienced significant decreases in blood glucose and blood pressure, along with an increase in lean mass.   A small, but statistically significant decrease in body fat levels was noted.

The subjects received 500 mg per day of Cinnulin PF,  a water extract of cinnamon.
