Cinnamon supplementation significantly increases HDL-C (good cholesterol) levels in patients with Type 2 Diabetes.
Cinnamon may offer a small boost to your 'good' cholesterol (HDL). While this is a positive metabolic marker, it is not a substitute for exercise or prescribed lipid-lowering medications.
GoodSupportsHIGH confidence
Cinnamon also increased levels of HDL-C (1.66 mg/dL; 95% CI, 1.09 to 2.24 mg/dL).
Why this rating
Meta-analysis shows low heterogeneity (I2=0%) for HDL-C, making this a robust finding within the study.
