Flavanol-rich dark chocolate (DC) and green tea extract capsules (GT) were assessed for effects on markers of vascular health. Commercially available dark chocolate was analysed for flavanol and methylxanthine levels using HPLC. There was considerable variation between brands of high cocoa solid content, and epicatechin (EC) levels did not correlate with calculated % non-fat cocoa solids. EC-rich DC also had considerably high methylxanthine levels. EC-rich DC was used to assess acute endothelial fitness. EndoPAT index (PAT) was determined in fingertips (3 subjects). PAT was not affected by dark chocolate ingestion, but systolic blood pressure (SBP) increased significantly by 5.2±4.9 mmHg (p
