Cinnamon Could Slow Blood Sugar Rise, But It’s No Diabetes Cure

Evidence that cinnamon lowers blood sugar is mixed and typically small; it may help insulin use and slow glucose absorption, but it’s not a cure or a replacement for diet, exercise, or diabetes meds. Most studies look at 1/2–1 teaspoon daily, and differences between cassia and Ceylon are minor. Turmeric/curcumin might help as well, but effective results in studies usually require higher-dose supplements. Use cinnamon as a flavorful addition to a balanced, fiber-rich diet rather than the main intervention for blood sugar control.
