Cinnamon does not improve cholesterol levels in diabetic patients

For diabetic patients hoping to improve their lipid profile, cinnamon supplementation has not shown benefit. While it does not appear to cause significant harm, the evidence does not support its use for lipid management in diabetes.

Published: January 1, 2011

This systematic review examined cinnamon supplementation specifically in patients with diabetes. The bulk of available evidence from small randomized controlled trials with heterogeneous results indicates that cinnamon supplementation neither improves serum lipid levels nor causes significant harm in diabetic patients. The strength of recommendation is rated B, reflecting the limitations of the evidence base including small sample sizes and inconsistent results across studies. No significant adverse effects were reported in the diabetic population beyond the mild gastrointestinal symptoms noted in healthy individuals.

Cinnamon powder infusion may help lower post-meal blood sugar

Ceylon cinnamon (Cinnamomum zeylanicum) contains polyphenols that may enhance insulin receptor sensitivity, potentially improving glucose absorption and helping reduce blood glucose levels toward normal ranges in type 2 diabetes patients.

A non-randomized interventional study with 54 type 2 diabetes patients divided into three groups: 8g cinnamon powder infusion (n=18), 10g cinnamon powder infusion (n=18), and control (n=18). After 14 days of daily consumption alongside prescribed medications, both treatment groups showed significant reductions in 2-hour postprandial fasting glucose levels (p<0.05). The 10g group demonstrated the most significant change (p=0.000), followed by the 8g group (p=0.001), while the control group showed no significant difference (p=0.652). All participants continued their prescribed diabetes medications throughout the study period.
