Pine Bark Extract Has No Impact On Risk Of Heart Disease – Study

Although found to be safe, pine bark extract administered at 200 milligrams a day had no impact on blood pressure or other heart disease risk factors, a U.S. study has concluded. Scientists theorized that pine bark extract could help high blood pressure because it has been shown to relax blood vessels constricted by stress hormones. In the randomized, placebo-controlled clinical trial, 130 people at increased risk for cardiovascular disease were consumed either 200 milligrams of pine bark extract or a placebo each day for 12 weeks. At the end of the trial, researchers tracked measured blood pressure and found no differences between those who took pine bark and those who took placebo. They acknowledged, however, that different dosages or formulations might produce different results.
