Ginkgo Biloba
Review the scientific evidence and bio-availability of Ginkgo Biloba, followed by our curated database of formulations.
Ginkgo Biloba (Ginkgo biloba L.) is one of the oldest living tree species, often referred to as a “living fossil” with a history in Traditional Chinese Medicine dating back thousands of years. Modern scientific applications focus primarily on standardized extracts (such as EGb 761) derived from the dried green leaves, which are utilized to support neural resilience, vascular function, and antioxidant status.
Clinical Benefits & Mechanism of Action
The supportive properties of Ginkgo Biloba are attributed to its complex profile of bioactive compounds, primarily flavonoid glycosides (quercetin, kaempferol) and terpene lactones (ginkgolides A, B, C, and bilobalide). Its physiological mechanisms include:
- Vascular Support and Microcirculation: Ginkgo supports the natural synthesis of nitric oxide (NO) and helps modulate the release of endothelin-1, contributing to normal vascular resistance and encouraging healthy cerebral blood flow.
- PAF Pathway Modulation: Ginkgolides interact with Platelet-Activating Factor (PAF) pathways. By occupying PAF binding sites on platelets and leukocytes in a balanced manner, the extract helps maintain normal blood viscosity and supports a healthy inflammatory response baseline.
- Neural Resilience and Mitochondrial Support: Bilobalide and flavonoids assist in scavenging reactive oxygen species (ROS) and support mitochondrial respiratory chain enzymes, helping to manage oxidative stress and protect cellular integrity within the nervous system.
- Neurotransmitter Balancing: Research suggests Ginkgo may modulate monoamine oxidase (MAO-A and MAO-B) activity and support the density of muscarinic acetylcholine receptors in the hippocampus, helping to maintain healthy cognitive vitality during aging.
