Daily supplements of Pycnogenol® (pine bark) may boost vascular health in people with stable coronary artery disease. Eight weeks of supplementation with Pycnogenol® were associated with significant improvements in the function of the cells lining blood vessels (endothelial cells), report researchers from the University Hospital Zurich and the University of Zurich.
200 mg per day of the pine bark extract resulted in an increase in flow mediated dilation (FMD) from 5.3 to 7.0, while no such improvements were observed for placebo. FMD is a measure of a blood vessel’s healthy ability to relax.
Pycnogenol is a combination of procyanidins, bioflavonoids and organic acids extracted from the bark of the maritime pine.
Results showed that eight weeks of supplementation with Pycnogenol was associated with a significant increase in artery dilation of 32%, while it remained unchanged in the placebo group.
