This study was planned to investigate the effects of supplementation of cinnamon on fasting blood glucose levels and lipid profiles among type2 diabetic patients. 60 subjects with type 2 diabetes from both sexes (30 males and 30 females) were allocated to the intervention and control groups (30 individuals per group). The doses of 1.5 g of cinnamon were equally administered orally in the form of cinnamon powder into 500 mg per capsule with breakfast, lunch, and dinner for 60 days. Control group received capsules of containing placebo. Blood samples were obtained on the beginning day of the experiment and at the end of 60 days. The fasting blood glucose levels and lipid profiles including total cholesterol, LDL-C, HDL-C and triglycerides of types 2 subjects were measured. Fasting blood glucose levels and lipid profiles in intervention group were significantly lower than control group (p<0.05). The average of fasting blood glucose levels, total cholesterol, cholesterol LDL and triglyceride levels were decreased after consumption of cinnamon powder, significantly(p<0.05). We observed no significant changes in fasting blood glucose levels and lipid profiles after consumption of placebo in control group. Conclusion: This study showed that consumption of cinnamon supplementation may be useful in control and decreasing of fasting blood glucose levels and lipid profiles among type 2 diabetes individuals
