What it is: Ginkgo biloba is an ancient tree extract used in traditional medicine to support blood flow, memory, and cognitive aging. It contains ginkgo flavones and terpenoids that improve cerebral and peripheral circulation while providing antioxidant neuroprotection.
Benefits
Cognitive Function & Memory
- Improves memory and learning
- Supports mental clarity and focus
- Reduces age-related cognitive decline
- Enhances information processing
- Neuroprotective effects
Circulation & Blood Flow
- Improves cerebral blood flow
- Supports peripheral circulation
- Enhances oxygen delivery to tissues
- Supports vascular function
- May improve exercise performance
Aging Brain Support
- Particularly valuable for cognitive aging
- Reduces neuroinflammation
- Protects neurons from oxidative stress
- Does not prevent dementia: large randomized trials (GEM, GuidAge) found no reduction in dementia or Alzheimer’s incidence; evidence for symptomatic memory benefit is modest and mixed
- Supports healthy aging
Antioxidant & Neuroprotection
- Potent antioxidant activity
- Protects brain cells from damage
- Reduces oxidative stress
- Complements healthy aging
Dosage
Cognitive support: 120-180 mg daily Enhanced: 180-240 mg daily (often 60 mg three times daily) Timing: With meals Duration: 4-8 weeks for initial effects; 12+ weeks for full cognitive benefits
Best Forms
Ginkgo Extract (Recommended)
- Standardized to flavones and terpenoids
- Concentrated, effective form
- Consistent results
- Most research uses extract
Research
Improves memory and cognitive function. Supports blood flow and cerebral oxygenation. Reduces age-related cognitive decline. Safe with long history of use.
Safety
Generally well-tolerated, but ginkgo can increase bleeding risk through its antiplatelet activity (ginkgolide B antagonizes platelet-activating factor). There are rare case reports of serious spontaneous bleeding, including intracranial and subdural hemorrhage. Avoid combining ginkgo with anticoagulants (e.g., warfarin), antiplatelets (e.g., clopidogrel), aspirin, or NSAIDs, or use only under medical supervision. Discontinue ginkgo 1-2 weeks before any scheduled surgery or dental procedure. Ginkgo may also lower the seizure threshold and reduce the effectiveness of anticonvulsant medications, and raw ginkgo seeds can contain ginkgotoxin, which carries a seizure risk; people with epilepsy or a seizure disorder, or anyone taking seizure medication, should avoid ginkgo or consult a physician first.
Stacking
For cognitive aging: Ginkgo 180 mg + Gotu Kola 500 mg + Bacopa 300 mg + Lion’s Mane 1g
For circulation: Ginkgo 180 mg + Hawthorn 600 mg + L-Arginine 2g + Carnosine 1g
For memory: Ginkgo 180 mg + Bacopa 300 mg + Vitamin B12 1,000 mcg + Choline 550 mg
Bottom Line
Ancient tree extract supporting memory, blood flow, and cognitive aging through proven mechanisms.
Key takeaways:
- Cognitive and circulation support
- Dose: 120-240 mg daily with meals
- Results in 4-8 weeks; full benefits 12+ weeks
- Can increase bleeding risk; avoid with blood thinners/aspirin/NSAIDs and stop 1-2 weeks before surgery
- Synergizes with gotu kola, bacopa, lion’s mane
- Valuable for cognitive aging and memory
