Brief Summary

Type 2 diabetes mellitus is considered a serious public health problem that has been raising worldwide. In Mexico, it is an important cause of morbi - mortality and it´s characterized by hyperglycemia that promotes an increase of cardiovascular risk through the impairment of arterial stiffness and endothelial function, which, in a chronic manner promotes the development of micro and macrovascular complications. Many nutraceuticals have been currently implemented aimed to improve glycemic control, and reduce cardiovascular risk and it´s complications, which results in a better quality of life in patients with type 2 diabetes mellitus. Cassia cinnamon pulverized bark has demonstrated to have vasodilator effect independent of endothelial mechanisms, probably regulating calcium influx or release into or within the cell, the later demonstrated in mice.

Outcome Measures

Primary Outcomes (3)

  • Brachial - ankle pulse wave velocity
