Product Details

Brief Introduction

Pine bark extract comes from the bark of the European coastal pine, pinus maritime. The rough bark of this particular pine tree contains a rich source of flavonoids.

Recent research suggests that many of the compounds found in pine bark such as oligomeric proanthocyanidin complexes Proanthocyanidins (OPCs) act as a powerful antioxidant in the human body. These OPCs are among the most potent antioxidants existing today and they seem to help cells defend against the damages of free radicals. They can even result when food is converted to energy.
