New cinnamon clinical trial in Florida
April 02nd 2007 Posted to DiabetesA new clinical study into the use of cinnamon in the care of type 2 diabetes (Non-Insulin Dependent Diabetes Mellitus - NIDDM) has just started at the Eglin AFB Regional Hospital in Florida, USA.
The trial is designed to run from March 2007 to August 2007 for 140 patients with type 2 diabetes between 18 - 90 years of age.
From the official study:
As the worldwide incidence of diabetes increases, the search for dietary adjuncts to treat this life-altering disease becomes far ranging. Cinnamon is purported to be a natural insulin sensitizer without any known adverse effects. Both in vitro and in vivo animal studies have shown that cinnamon is an insulin sensitizer1. Several compounds within cinnamon have been identified as possible sources of this sensitization process.
To-date, three small randomized trials studying cinnamon in human diabetics have been published. Khan et al. reported that fasting serum glucose could be reduced by 18-29% after 40 days of supplementation with 1, 3, or 6 g of cinnamon (Cinnamomum cassia) in type 2 diabetics. 2 This study had several limitations that included failure to measure hemoglobin A1C, all patients were Pakistani, and no power analysis was documented. Vanschoonbeek, et al.3 report a small RCT of postmenopausal women with well-controlled type 2 diabetes which showed no change in HbA1C or fasting glucose. Once again no power analysis is reported. Mang et al. 4 conducted a RCT of type 2 diabetics treated with aqueous extract of cinnamon for 4 months. They report a 15% decrease in fasting glucose and no change in HbA1C over the duration of this trial. Subjects had HbA1C less than 7% and again no power analysis was included in this study.
This study will address whether cinnamon at the dose of 1g daily in addition to usual care lowers hemoglobin A1c compared to usual care. Power analysis indicates that 63 per group are needed and we will recruit 70 patients.
