Does consumption of cinnamon lead to a decrease in blood pressure levels?

Answer from top 0 papers

Cinnamon supplementation appears to have a positive effect on lowering blood pressure, particularly in individuals with type 2 diabetes or prediabetes.
Multiple studies have demonstrated significant reductions in both systolic and diastolic blood pressure following cinnamon intake. A meta-analysis of 9 trials involving 641 subjects found that cinnamon supplementation resulted in significant reductions in systolic blood pressure (SBP) by 6.23 mmHg and diastolic blood pressure (DBP) by 3.93 mmHg (). Another study on type 2 diabetic patients showed significant reductions in SBP (from 132.6 to 129.2 mmHg) and DBP (from 85.2 to 80.2 mmHg) after 12 weeks of 2g daily cinnamon supplementation ().
Interestingly, the blood pressure-lowering effects of cinnamon seem to be more pronounced with lower doses and longer durations. Studies using ≤2 g cinnamon for ≥12 weeks showed greater effects on SBP, especially in participants aged <50 years (). However, the relationship between cinnamon dosage, study duration, and blood pressure reduction was not found to be strictly linear ().
In conclusion, while cinnamon shows promising effects on blood pressure reduction, more long-term, adequately powered randomized controlled trials involving larger patient populations are needed to fully assess its clinical potential for blood pressure control (). Nevertheless, current evidence suggests that cinnamon supplementation could be considered as an additional dietary option to help regulate blood pressure levels, particularly in conjunction with conventional medications for type 2 diabetes management ().
