Cinnamon extract lowers glucose, insulin and cholesterol in people with elevated serum glucose
Cinnamon ( 肉桂 ròu guì ) has in vitro insulin potentiating activity , and proanthocyanidins from cinnamon prevent in vitro formation of advanced glycation end products . Some human studies were equivocal , but several have shown beneficial effects of cinnamon supplementation on circulating glucose , lipids , and /or insulin . This placebo-controlled double-blind trial tested the effects of a dried water extract of cinnamon ( Cinnamomum cassia ) on circulating glucose , lipids , insulin , and insulin resistance . Men and women from Beijing and Dalian , China , were invited to participate if they had fasting serum glucose > 6.1 mmol/L or 2-h glucose > 7.8 mmol/L. Participants , ( 173 were enrolled and 137 completed the study ) were r and omly assigned to receive either a spray-dried , water extract of cinnamon ( CinSulin ® ) , 250 mg/capsule , or a placebo , twice a day for two months . Mean ± SEM age of participants was 61.3 ± 0.8 years , BMI was 25.3 ± 0.3 and M/F ratio was 65/72 .  After 2 mo , fasting glucose decreased ( p < 0.001 ) in the cinnamon extract-supplemented group ( 8.85 ± 0.36 to 8.19 ± 0.29 mmol/L ) compared with the placebo group ( 8.57 ± 0.32 to 8.44 ± 0.34 mmol/L , p = 0.45 ) . Glucose 2 h after a 75 g carbohydrate load , fasting insulin , and HOMA-IR also decreased with cinnamon extract compared with  placebo . Total and LDL-cholesterol decreased with cinnamon extract and HDL-cholesterol decreased in both the cinnamon-extract and placebo groups . In conclusion , supplementation with 500 mg of water-extract of cinnamon for two months reduced fasting insulin , glucose , total cholesterol , and LDL cholesterol and enhanced insulin sensitivity of subjects with elevated blood glucose
