Maritime Pine Bark Extract
A 2014 Pycnogenol study (Belcaro et al.) in healthy professionals aged 35–55 reported small but significant cognitive improvements and a 30.4% drop in plasma free radicals after 12 weeks at 150mg/day — but it was a non-randomized product-evaluation registry study, not an RCT. A 2011 controlled (non-randomized) study in students (Luzzi et al.) reported better attention, memory and exam scores over 8 weeks. Both come from the same Irvine3 Labs / Chieti-Pescara author group, which has published numerous Pycnogenol studies; Pycnogenol is a Horphag Research trademark, and these trials are widely reported as industry-supported, though no sponsor is disclosed in the abstracts. The independent 2020 Cochrane review rated the evidence for every pine bark outcome it assessed as very low certainty. A 2025 network meta-analysis ranked Pycnogenol highly for mild cognitive impairment but cautioned about heterogeneity.
Evidence reviewed:
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 a branded form.

Human effect matrix
Based on human clinical trials only. Animal and in-vitro data excluded.
| Effect | Evidence | Magnitude | Studies |
|---|---|---|---|
| Attention & Focus | preliminary | Small | 3 |
| Oxidative Stress Reduction | preliminary | Moderate | 1 |
| Cerebral Blood Flow | moderate | Small | — |
| Memory | preliminary | Small | 2 |
Evidence key: Strong = multiple consistent RCTs · Moderate = smaller/fewer RCTs · Preliminary = early trials or small n · Mixed = conflicting results
Documented benefits
- Lower oxidative stress markers
- Attention and focus (preliminary, non-randomized studies)
- Antioxidant activity
Side effects & cautions
- Generally well tolerated, though adverse-event reporting was inconsistent across trials (Cochrane 2020)
- Rare: mild GI discomfort
- Headache (uncommon)
- Immunosuppressants: possible interaction, not confirmed by clinical reports — ask your doctor
How to take
Stacking recommendations
Ingredients that pair well with Maritime Pine Bark Extract and why.
Both are studied for attention, and both are in Performance Lab Mind; we cite no trial of the pairing.
Pine Bark is studied for cerebral blood flow; L-Tyrosine is an amino acid precursor to dopamine and norepinephrine. We cite no trial of the pairing.
Pine Bark contains proanthocyanidins, polyphenol antioxidants; DHA is the primary structural omega-3 fatty acid in the brain. We cite no trial of the pairing.
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 the extract used in the studies we cite (Belcaro 2014; Luzzi 2011); we found no trial comparing it with generic pine bark extract. Generic pine bark extracts may vary in composition. To match that evidence, choose Pycnogenol.
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. No trial has tested the combination, and ginkgo raises bleeding risk with blood thinners.
Can I take Pine Bark Extract long-term?
The pooled trials ran from 4 weeks to 6 months, and the Cochrane review notes adverse events were reported inconsistently, so the absence of reported harm is not proof of long-term safety. No cycling protocol has been tested. Check with your doctor if you take 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 on this page (the Belcaro 2014 study we cite used 150mg/day). It sits in a multi-ingredient formula with Citicoline and Tyrosine, but it is still underdosed relative to the standalone evidence.
