Frequently Asked Questions

Does ginkgo biloba actually work for memory?

The evidence is nuanced. For healthy young adults, ginkgo shows minimal cognitive benefit. For older adults with existing mild cognitive impairment or early dementia, standardized EGb 761 at 240mg/day consistently shows modest improvements in memory, attention, and daily functioning across European trials. It is not a memory miracle pill, but it has real, clinically validated effects in the right population.

Is ginkgo biloba safe with blood thinners?

Ginkgo should be used with caution alongside blood thinners. Its ginkgolides inhibit platelet-activating factor (PAF), which can theoretically increase bleeding risk. While clinical trials have not consistently shown dangerous interactions, most guidelines recommend avoiding the combination or using only under medical supervision. Stop ginkgo at least 2 weeks before surgery.

How long does ginkgo take to work?

Most clinical trials measure outcomes at 8-12 weeks, with some showing initial improvements by 4-6 weeks. Ginkgo works through gradual improvements in cerebral blood flow and antioxidant protection rather than acute stimulation. Consistent daily use for at least 8 weeks is recommended before evaluating effectiveness.
