Ginkgo Biloba

Gets more oxygen to your brain — think faster, react quicker

01 — OVERVIEW
SYSTEMSHow Ginkgo Biloba affects you

Boosts brain circulation.

Terpene lactones and flavonoids improve cerebral blood flow and capillary integrity — particularly helpful when mild age-related blood-flow decline is the bottleneck.

  • Best-supported benefit: working memory and speed of processing in older adults.
  • Consistent dosing over 6–12 weeks produces measurable cognitive effects.
  • Standardized EGb 761 extract is the most studied form.

Your brain is an oxygen hog — it uses 20% of all the oxygen in your body. Ginkgo comes from one of the oldest tree species on Earth, and it works by opening up blood vessels in your brain so more oxygen and nutrients can flow in. Think of it like unclogging the pipes to your brain's water supply. More blood flow = more fuel for thinking, faster reaction times, and better working memory.
