Long-term administration of vitamin C reverses endothelial vasomotor dysfunction in patients with coronary artery disease.
Researchers took patients with documented coronary artery disease to take a single oral dose of either 2 g vitamin C or placebo. The dose of vitamin C improved flow-mediated dilation of the brachial artery, as assessed by high-resolution vascular ultrasound 2 hours later. The researchers report that the effect was sustained among patients who subsequently took 500 mg of vitamin C daily for 30 days.
