Some clinical studies with human subjects have investigated how Pycnogenol may help with circulation in the capillaries, which are the body’s smallest blood vessels.
Capillary health is important because these tiny blood vessels play a role in delivering oxygen, blood and nutrients to the tissues, regulating blood pressure and other health-essential activities.
One Pycnogenol research study tracked 60 patients between the ages of 45 and 75 with coronary artery problems. Over four weeks, half the patients received 150 mg of Pycnogenol three times daily while the rest received a placebo. Throughout the study, patients were tested for microcirculation, platelet function, and other factors.
- At study’s end, researchers reported that 53% of the Pycnogenol participants experienced an improvement in microcirculation and an increase in the diameter of their micro vessels. Additionally, the researchers found that clotting of “sticky” blood cells was significantly decreased in the group taking 150 mg, which may suggest additional Pycnogenol circulation benefits.
