Ginkgo biloba Leaf Extract

Ginkgo biloba is a plant with neuroprotective, nootropic and adaptogenic effects. Ginkgo biloba can delay aging, improving memory and attention.

Scientific Name:
Ginkgo biloba


      • Contains flavonoid glycosides such as quercetin, and terpene lactones such as ginkgolides and bilobalides – main bioactive substances[1]
      • Increases dopamine, acetylcholine and noradrenaline levels[2,3]
      • Modulates histaminergic neurotransmission improving learning and memory[4]
      • Increases BDNF levels and promotes neurogenesis and neuronal survival[5]
      • Improves cerebral blood flow by inhibiting the platelet activating factor (PAF) receptor[6]
      • Delays cognitive decline and improves short term memory and free recall[7]
      • Reduces stress and anxiety and decreases corticosterone levels – adaptogenic effect[8]
      • Has antioxidant and anti-inflammatory effects and preserves mitochondrial function – anti-aging effect[9]
