Ginkgo Biloba Powder
Also known as: Ginkgo biloba, maidenhair tree, EGb 761, ginkgo extract, Salisburia adiantifolia
Effective Dosage
120-240 mg daily (general knowledge; no study data provided)
What the Science Says
Ginkgo biloba is an extract from one of the world's oldest tree species, used in traditional medicine for thousands of years. It contains flavonoids and terpenoids thought to support blood flow and act as antioxidants, which is why it's commonly marketed for memory, focus, and cognitive aging. Based on general knowledge, some studies have explored its use in older adults with cognitive decline, but results across the broader research literature are inconsistent and no supporting papers were provided here.
What It Doesn't Do
Won't prevent Alzheimer's disease — large trials have found no protective effect. Won't sharpen memory in healthy young adults. Not a proven treatment for tinnitus or vertigo despite common marketing claims. No evidence it reverses cognitive decline once it has started.

Absorption & Bioavailability
Moderate — standardized extracts (typically 24% flavone glycosides, 6% terpene lactones) are better absorbed than raw powder; raw powder form may have inconsistent potency and absorption.
Red Flags to Watch For
- Ginkgo biloba can thin the blood and increase bleeding risk — dangerous if combined with blood thinners like warfarin or aspirin
- Raw or unprocessed ginkgo seeds and leaves contain ginkgotoxin, which can cause seizures — only standardized extracts should be used
- May interact with antidepressants (SSRIs, MAOIs) and anticoagulant medications — always consult a doctor before use
- No papers were provided to support any specific health claims — all evidence here is based on general knowledge, not reviewed studies
- Products vary widely in standardization; 'ginkgo biloba powder' with no standardization label may deliver inconsistent or ineffective doses
