What the Science Says
Ginkgo biloba is an extract from one of the world's oldest tree species, used for centuries in traditional medicine. It is most commonly taken to support memory, mental clarity, and blood circulation, particularly in older adults. Based on general knowledge, doses of 120–240 mg of standardized extract daily have been studied, but no clinical papers were available to confirm specific outcomes here.
What It Doesn't Do
Won't reverse Alzheimer's disease or dementia. No solid proof it prevents cognitive decline in healthy adults. Not a substitute for medical treatment of any circulatory or neurological condition. The 'brain booster' marketing is far ahead of the actual evidence.
Evidence-Based Benefits
May modestly support short-term memory and recall in older adults.
Weak EvidenceEffective at: 120-240 mg daily
Traditionally used to support peripheral blood flow and reduce symptoms of poor circulation.
Weak EvidenceEffective at: 120-240 mg daily
May help slow cognitive decline in elderly individuals with mild impairment.
Weak EvidenceEffective at: 120-240 mg daily
Absorption & Bioavailability
Moderate — standardized extracts (typically 24% flavone glycosides, 6% terpene lactones) are generally considered better absorbed than raw powder, but raw powder form may have lower and more variable absorption.
Red Flags to Watch For
- Raw powder form is not standardized — potency and active compound levels vary widely between products
- Can interact with blood thinners (e.g., warfarin, aspirin) and increase bleeding risk
- May cause headaches, dizziness, or GI upset in some users
- Not recommended before surgery due to anticoagulant properties
- No papers were provided to support specific efficacy claims — evidence here is based on general knowledge only
