What Is Pycnogenol?
Pycnogenol is a standardized extract from the bark of the French maritime pine tree, grown exclusively in coastal southwest France. It contains a unique combination of procyanidins, bioflavonoids, and phenolic acids.
The extract is standardized to contain 65-75% proanthocyanidins (OPCs), which are powerful antioxidants — estimated to be 50 times more potent than vitamin E and 20 times more potent than vitamin C.
- Proanthocyanidins (OPCs): 65-75% — the primary active compounds
- Bioflavonoids: Catechin, epicatechin, taxifolin
- Phenolic acids: Caffeic, ferulic, gallic acids
- Antioxidant potency: 50x vitamin E, 20x vitamin C
- Bioavailability: Water-soluble, rapidly absorbed within 30 minutes
Circulation & Cardiovascular Health
Pycnogenol's strongest evidence is for circulatory health.
- Capillary health: Strengthens capillary walls, reduces leakage
- Venous insufficiency: Reduces leg swelling, pain, and heaviness
- Blood flow: Increases nitric oxide production by 30%
- Blood pressure: Mild reduction (3-5 mmHg systolic)
- Platelet function: Inhibits platelet aggregation (natural blood thinner)
Skin Health & Anti-Aging
Pycnogenol has demonstrated remarkable benefits for skin.
- UV protection: Internal SPF boost, reduces sunburn severity
- Collagen: Protects and stimulates collagen production
- Elastin: Protects elastin from degradation
- Hyperpigmentation: Reduces melasma and age spots
- Skin hydration: Increases hyaluronic acid production
Cognitive Function & ADHD
Pycnogenol shows promise for brain health and attention disorders.
- ADHD in children: Studies show improvement in attention and hyperactivity
- Memory: Enhances working memory and cognitive performance
- Oxidative stress: Protects neurons from free radical damage
- Blood-brain barrier: Crosses BBB readily
- Children's safety: Well-tolerated in pediatric studies
Erectile Dysfunction & Sexual Health
Pycnogenol combined with L-arginine has shown impressive results for ED.
- ED studies: 92% improvement when combined with L-arginine (3g)
- Mechanism: Protects NO from degradation, extends its effects
- Sperm quality: Improves sperm count and motility
- Women: May improve sexual function in women
- Fertility: Supports overall reproductive health
Dosage & How to Take Pycnogenol
Dosage varies by condition.
- General antioxidant: 50-100mg daily
- Circulation: 100-200mg daily
- Skin health: 75-150mg daily (with vitamin C for synergy)
- ADHD: 1mg per kg body weight daily for children
- ED: 120mg Pycnogenol + 3g L-arginine daily
- Take with meals: Better absorption with food
Safety & Considerations
Pycnogenol has an excellent safety profile from decades of research.
- Side effects: Rare, mild digestive upset
- Blood thinners: May enhance antiplatelet effects
- Immune suppressants: May stimulate immune function
- Diabetes meds: May enhance glucose-lowering effect
- Pregnancy: No safety data, avoid without medical advice

Frequently Asked Questions
Is Pycnogenol worth the premium price?
Pycnogenol is one of the most researched botanical extracts with 400+ clinical studies. For specific conditions like venous insufficiency, ADHD, or ED, the clinical evidence justifies the cost. For general antioxidant use, less expensive pine bark extracts may be sufficient.
Can Pycnogenol replace my blood pressure medication?
No. While Pycnogenol may modestly reduce blood pressure (3-5 mmHg), it should not replace prescribed medications. It can be used as a complementary supplement with your doctor's knowledge. Monitor blood pressure closely if combining.
How does Pycnogenol compare to grape seed extract?
Both contain proanthocyanidins (OPCs), but Pycnogenol has more clinical research behind it. Grape seed extract is less expensive and contains higher OPC concentrations. For most people, grape seed extract is a cost-effective alternative, while Pycnogenol may be preferred for specific clinical applications like ADHD or ED.
