Maritime Pine Bark Extract
Mechanism of Action
Maritime Pine Bark Extract (Pinus pinaster) contains proanthocyanidins — potent polyphenol antioxidants that cross the blood-brain barrier. It works via three pathways: (1) stimulating endothelial nitric oxide synthase (eNOS) to increase cerebral blood flow via vasodilation; (2) scavenging reactive oxygen species to protect neuronal membranes; (3) modulating NF-κB inflammatory signalling to reduce neuroinflammation. Pycnogenol is the most studied branded form.
Clinical Evidence Summary
A 2014 Pycnogenol RCT (Belcaro et al.) in healthy professionals showed significant improvements in attention, memory, and executive function after 12 weeks at 150mg/day. A 2012 trial in elderly subjects found improved cognitive function and reduced oxidative stress markers. The evidence base is smaller than for ingredients like Bacopa or Ginkgo but consistently positive. Most studies use the branded Pycnogenol extract (65-75% proanthocyanidins).
Human Effect Matrix
Based on human clinical trials only. Animal and in-vitro data excluded.

How to Take
Stacking Recommendations
Ingredients that pair well with Maritime Pine Bark Extract and why.
Citicoline provides cholinergic focus; Pine Bark provides blood flow and antioxidant support. Together they form the core of Performance Lab Mind — a minimal, evidence-based focus stack.
Pine Bark supports cerebral blood flow (delivery); Tyrosine supports catecholamine synthesis (production). Complementary supply-side + demand-side pairing.
Pine Bark protects neuronal membranes from oxidative damage; DHA provides the structural fatty acid for those membranes. Protective + structural combination.
Frequently Asked Questions
What is Pycnogenol and is it worth the premium?▾
Pycnogenol is a patented extract of French Maritime Pine Bark (Pinus pinaster) standardised to 65-75% proanthocyanidins with a specific manufacturing process. It is used in 90%+ of published clinical trials on pine bark. Generic pine bark extracts may vary in composition. If you want to match the clinical evidence, Pycnogenol is the most reliable choice.
How does Maritime Pine Bark compare to Ginkgo Biloba?▾
Both improve cerebral blood flow but via different mechanisms: Ginkgo inhibits platelet-activating factor; Pine Bark stimulates nitric oxide. Pine Bark has stronger antioxidant activity; Ginkgo has a larger evidence base for cognitive decline. They can be combined safely for complementary cerebrovascular support.
Can I take Pine Bark Extract long-term?▾
Yes. Studies up to 12 months show no safety concerns at 100-200mg/day. No cycling is required. The antioxidant benefits are cumulative, so consistent daily use is recommended. No significant drug interactions at standard doses, though caution with immunosuppressants.
Why is the dose in Performance Lab Mind only 75mg?▾
Performance Lab Mind uses 75mg Maritime Pine Bark — below the 100-200mg clinical dose used in most standalone trials. However, in a multi-ingredient formula with Citicoline and Tyrosine, the synergistic effects may partially compensate. It is still technically underdosed relative to the standalone evidence.
