This comprehensive guide explores everything you need to know about pine bark extract, including its origins, active compounds, potential health benefits, safety profile, and practical usage guidelines.

What is Pine Bark Extract?

Pine bark extract is a natural supplement derived from the bark of pine trees, particularly the French maritime pine (Pinus pinaster). These trees grow primarily in coastal regions of the Mediterranean, including France, Spain, Portugal, and Morocco.

The maritime pine features thick bark that displays various shades of brown, orange, and red. While over 100 species of pine trees exist worldwide, the maritime pine has become the primary source for commercial pine bark extracts due to its particularly rich concentration of beneficial compounds.

Historical Background

The medicinal use of pine bark dates back centuries. Indigenous peoples of North America traditionally used pine bark tea to treat scurvy and promote wound healing. In the 1940s, French scientist Jacques Masquelier began formally studying pine bark’s health effects after learning about these traditional uses.

Masquelier’s research laid the foundation for modern pine bark supplements, leading to the development of standardized extracts that are widely available today.

Common Brand Names

Pine bark extract is sold under several trademarked names, including:

• Pycnogenol – The most widely recognized brand, standardized to contain at least 75% procyanidins
• Oligopin – Another popular maritime pine bark extract
• Flavangenol – A standardized pine bark extract from Japan

Manufacturing Process

The production of pine bark extract involves several steps:

1. The bark is carefully harvested and ground into small pieces
2. The ground bark undergoes washing and soaking in hot water
3. Solid materials are filtered out, leaving a liquid extract
4. The liquid may be used as-is or freeze-dried and ground into powder form

This extraction process concentrates the beneficial compounds found naturally in the bark, making them more readily available for supplementation.

Active Compounds in Pine Bark Extract
