Aged Garlic Extract Study

The primary intention of the study is to examine the effect of aged garlic extract (AGE) on the absolute change in coronary artery calcium (CAC). The second intention is to examine the effect of AGE on inflammatory biomarkers and microcirculation. It is a double blind placebo controlled study. The participants will ingest AGE during a period of one year. The CAC will be controlled by computer tomography (CT) scan; the inflammatory biomarkers through blood sample test and the microcirculation through laser speckel imagining and laser doppler before and after the one year period of AGE ingestion.
