The purpose of this research study is to see the effect of taking Aged Garlic Extract (AGE) on the progression of coronary plaque, a condition called atherosclerosis, in people diagnosed with Diabetes.

This clinical trial is to determine on progression rates of low attenuation plaque under influence of Aged Garlic Extract as compared to placebo over the 1year period in individuals with Type 2 Diabetes Mellitus.The study also examines the effect of Aged Garlic Extract on endothelial function and arterial stiffness which was measured by cardio-ankle vascular index (CAVI) over the 3months period.
