Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
This supplement has been used in connection with the following health conditions:
Chronic Venous Insufficiency
150 to 300 mg per day
A controlled study reported that supplementing daily with Pycnogenol improved symptoms of chronic venous insufficiency and reduced associated leg swelling.
Though another story did not find effect, one study reported that Pycnogenol reduced symptoms of hyperactivity and improved attention, coordination, and concentration after one month in a group of children with ADHD.
For plane travel: 200 mg two to three hours before a flight, 200 mg six hours later, and 100 mg on the following day
People at risk for venous thrombosis during plane travel were shown a video explaining in-flight exercises to prevent venous thrombosis and also followed a regimen of Pycnogenol, which appears to reduce frequency of episodes of venous thrombosis.
A preliminary study of people experiencing at least four episodes per week of leg cramps due to either athletic activity, circulatory disorders, or unknown causes reported that Pycnogenol significantly reduced cramping.
Traditional Use (May Not Be Supported by Scientific Studies)
While the French maritime pine has been used as an ornamental tree and for wood products, it has not been used in traditional herbal medicine. Pycnogenol was developed and patented in the 1980s as a rich source of proanthocyanidins.
