Effect of oral cinnamon intervention on metabolic profile and body composition of Asian Indians with metabolic syndrome: a randomized double -blind control trial

Study answer

What this study found

Cinnamon produced overall favorable effects on metabolic syndrome features and the authors concluded it may be a cost-effective dietary intervention. Compared with placebo, cinnamon significantly improved fasting blood glucose, HbA1c, total cholesterol, triglycerides, HDL, systolic blood pressure, and diastolic blood pressure; for example, adjusted between-group differences were 0.3 mmol/L for FBG, 2.6 mmol/mol for HbA1c, 0.42 mmol/L for total cholesterol, 0.20 mmol/L for triglycerides, 8.3 mmHg for systolic BP, and 6.9 mmHg for diastolic BP. Postprandial glucose also improved after…

Study & population

Randomized, double-blind, placebo-controlled trial in treatment-naive Asian Indian adults with metabolic syndrome recruited from a private hospital and clinic in South Delhi, India.

Intervention

Oral cinnamon was given at 3 g/day for 16 weeks as six 500 mg capsules daily, taken as two capsules after breakfast, lunch, and dinner.

Key limitation

The trial was relatively small, short in duration, and conducted in a single North Indian setting, which limits generalizability.
