How long does ginkgo biloba take to work?

Longer than you would like. The trials ran for months and years, and they measured outcomes on cognitive tests rather than on how anyone felt. Most people will not notice anything at all, and this is not a supplement you can sensibly assess after a fortnight of taking it.

Ginkgo or bacopa for memory?

Different evidence bases, neither of them strong. What ginkgo has is rigour: it was tested in large, long trials, and those largely came back negative. That is more than can be said for most alternatives, where the absence of a negative result mainly reflects the absence of a proper test.

Is ginkgo biloba tea the same as the supplement?

No. Tea is not standardised, so the dose of active compounds is unknown and varies from cup to cup. All the research used a specific standardised extract, EGb 761, at a specific daily dose. Drinking the tea is not a lower-key version of that; it is a different thing.

Should you take ginkgo with or without food?

No evidence favours either, so take it whichever way you will remember. What the trials actually did was split the dose across the day, 120 mg twice daily rather than 240 mg in one go. That detail matters more than whether there is food in your stomach.

Can ginkgo cause headaches?

Yes. Headache is among the more commonly reported side effects, along with upset stomach and dizziness. These are usually mild and tend to settle, though a headache that persists or worsens is worth stopping for and mentioning to your pharmacist.

How does it compare with ginseng or vinpocetine?

Ginkgo and ginseng are often sold combined, which makes those studies difficult to attribute to either one. Vinpocetine carries its own regulatory warnings, including in pregnancy, so it is not an interchangeable alternative. Comparing them is harder than product pages suggest.
