Ginkgo comes from the leaves of one of the oldest tree species on Earth. Standardized extracts lock in consistent levels of active compounds, mainly flavonoids and terpenoids.
Most people take it to support circulation, especially blood flow to the brain, along with mental clarity, memory, and focus. Others use it for mood, stress resilience, eye health, or occasional tinnitus.
A typical routine splits one to three doses across the day, taken with meals to help absorption. Steady daily use for several weeks usually passes before you notice any shift.
Ginkgo can raise bleeding risk, particularly with blood thinners like warfarin, aspirin, or NSAIDs. Watch for interactions with certain antidepressants and anticonvulsants. Skip it before surgery, if you have a bleeding disorder, or if you take anticoagulants unless a doctor clears it. Side effects are uncommon but may include headache, stomach upset, or skin reactions.
