Product Details

What is Pine Bark Extract?

PureBulk’s pine bark extract comes from the bark of the Pinus massoniana evergreen tree. Pinus massoniana tree trunks have scaly, grey-brown bark that turns flaky and orange-red higher up the trunk. They are native to Taiwan, central and southern China, and northern Vietnam. Its use in Chinese remedies dates back thousands of years, and people continue to take pine bark extract for its beneficial properties to do this day. Traditional Chinese cultures used the needles, bark, and turpentine of the Pinus massoniana tree to make folk remedies that promoted constriction and hemostasis to prevent and stop bleeding. They also used pine bark to detoxify, ease joint stiffness, and support healthy blood pressure.

Modern research has found that Pinus massoniana pine bark extract may provide potent antioxidant effects thanks to its proanthocyanidin content. Proanthocyanidin, also known as proanthocyanin, is a bioflavonoid that helps alleviate symptoms related to inflammation, circulation, and wound healing. It’s also the primary polyphenol found in red wine and may explain how red wine helps support heart health. PureBulk's Pine bark extract powder is standardized to contain at least 95% proanthocyanidins.

Potential Pine Bark Extract Benefits

Pinus massoniana pine bark extract is a powerful antioxidant. It can inhibit free radical attacks on linoleic acid, an essential fatty acid and critical component of neuronal cell membranes. It does so with much greater efficacy than α-tocopherol (vitamin E), another well-established antioxidant.

Pine bark extract also boasts better superoxide anion scavenging than many other antioxidant compounds, including quercetin and α-tocopherol. Superoxide anions are a type of free radical known as reactive oxygen species (ROS). When free radical levels exceed the available antioxidants, they damage cells that play biological roles, including proteins, nucleic acids, and lipids. Free radical damage also leads to oxidative stress and widespread inflammation, which science has linked to aging and several disease states.

Free radical scavengers like pine bark extract support general health and well-being by reducing cellular inflammation and restoring the necessary balance of oxidants and antioxidants. Pine bark extract can further protect cells by acting as an anticarcinogen and antimutagen. It also stimulates the immune system and inhibits the growth of harmful cells.

Potential Pine Bark Extract Side Effects

Most individuals can take pine bark extract without side effects. However, it may interact with immunosuppressants and medications for managing diabetes and blood clotting. Individuals should consult with a physician before starting any new supplement to avoid negative drug interactions and side effects.
