Overview
Maritime Pine Bark extract (Pycnogenol) is one of the most studied natural health products, with over 100 clinical trials. Its oligomeric proanthocyanidins (OPCs) provide broad-spectrum antioxidant, anti-inflammatory, and circulatory benefits. Studies confirm efficacy for chronic venous insufficiency, ADHD, menopausal symptoms, osteoarthritis, and cognitive function.
Traditional Use
The French explorer Jacques Cartier (1534) and his crew survived scurvy during a Canadian winter after indigenous peoples gave them a tea from pine bark and needles. This historical account inspired Dr. Masquelier in the 1950s to research OPCs in pine bark, leading eventually to the development of Pycnogenol. Maritime pine bark has been used in traditional medicine across coastal Europe for wound healing, venous complaints, and as an astringent tonic.
Key Active Compounds
Oligomeric Proanthocyanidins (OPCs / Procyanidins)
The most potent antioxidant bioflavonoids found in plant sources — 20× more potent than vitamin C and 50× more than vitamin E. Inhibit ACE (reducing blood pressure), reduce platelet aggregation, and stabilize collagen and elastin in blood vessel walls.
Catechins, Taxifolin, and Phenolic Acids
Additional polyphenol compounds contributing to anti-inflammatory (NF-kB inhibition), antiviral, and eNOS-activating (increasing nitric oxide and vasodilation) activities.
Evidence-Based Benefits
Chronic Venous Insufficiency
Strong evidenceMultiple RCTs demonstrate significant reduction in leg swelling, heaviness, cramps, and skin changes in CVI. Pycnogenol strengthens capillary walls and reduces microangiopathy.
ADHD in Children
Moderate evidenceA randomized double-blind trial showed Pycnogenol significantly improved attention, concentration, and reduced hyperactivity in children with ADHD. Considered a safe adjunct to conventional ADHD treatment.
Cardiovascular and Blood Pressure
Strong evidenceMultiple RCTs confirm ACE inhibition reduces blood pressure. Meta-analysis confirms significant blood pressure reduction. Platelet aggregation inhibition reduces cardiovascular event risk.
Common Preparation Methods
Standardized Extract (Pycnogenol)
Take Pycnogenol or equivalent standardized Maritime Pine Bark extract.
Dosage: 50–300mg daily (50–100mg for maintenance; 150–300mg for therapeutic conditions)This is the primary form used in all clinical trials. Look for 'Maritime Pine Bark extract' specifying OPC/procyanidin content. Take with meals. Allow 4–8 weeks for chronic conditions. Pycnogenol is the patented standardized form but generic OPC-standardized extracts are acceptable.
Safety & Cautions
Please read carefully before use
