Moderate confidence
Low bias
Última actualización 14 de junio de 2026

Conclusión Clave:

This study investigated the acute effects of raw cinnamon on post-meal glucose spikes in type 2 diabetes patients, finding that cinnamon in water reduced glucose spikes while capsules did not.

Efectos Principales

Cinnamon dissolved in water decreased postprandial blood glucose by 79 mg/dL.

Cinnamon intake flattened the glycemic curve, leading to a lower iAUC.

Cinnamon capsules did not show significant anti-hyperglycemic effects.

The control group exhibited typical postprandial hyperglycemia.
