- General cognitive support: 50–150 mg per day
- For attention and focus: 100–200 mg per day (doses used in ADHD studies)
- For elderly cognitive support: 150 mg per day (dose used in age-related cognitive studies)
- Pycnogenol: The most studied form - standardised to 65–75% procyanidins
- Timing: Can be taken with or without food; some prefer dividing the dose (morning and afternoon)
Watch out for
- Side effects: Generally very well tolerated. Occasional reports of mild GI discomfort, headache, and dizziness.
- Anticoagulant effects: May have mild blood-thinning properties. Use caution if taking anticoagulants (warfarin, aspirin) or before surgery.

- Pregnancy: Limited data - some studies suggest safety, but consult a healthcare provider.
- Allergies: Individuals with pine or tree allergies should exercise caution, though allergic reactions are rare.

- OPCs neutralise free radicals and regenerate other antioxidants (vitamins C and E), protecting neuronal membranes, DNA, and mitochondria from oxidative damage.
- Inhibits NF-kB and reduces pro-inflammatory cytokines (IL-1, IL-6, TNF-alpha), countering chronic neuroinflammation linked to cognitive decline.
- The small molecular size of OPCs allows them to cross the blood-brain barrier, providing direct antioxidant protection within the central nervous system.
