Ginkgo Biloba Extract (24%/6%) — botanical close-up

Reported Benefits (Provisional)

Enhances cognitive function by improving blood flow to the brain, which boosts memory and mental clarity. Studies show a 7% improvement in cognitive performance. - Supports cardiovascular health by increasing circulation and reducing blood viscosity, which lowers the risk of clot formation. - Acts as a powerful antioxidant, protecting brain cells from oxidative damage and slowing cognitive decline. - Reduces symptoms of anxiety by modulating neurotransmitter activity, promoting a sense of calm and well-being. - Improves vision health by enhancing blood flow to the eyes, which can slow the progression of age-related macular degeneration. - Supports respiratory health by reducing symptoms of asthma and improving lung function. - Enhances mood by increasing serotonin levels, which can alleviate symptoms of depression.

Origin & History

Natural habitat

Ginkgo biloba is derived from the leaves of the Ginkgo tree, native to China. The extract is standardized to contain 24% flavone glycosides and 6% terpene lactones. It is produced through a process of drying and extracting the active compounds from the leaves.

“Ginkgo biloba has been used in traditional Chinese medicine for thousands of years. It is one of the oldest living tree species, often referred to as a living fossil.”Traditional Medicine

Research Narrative (Provisional)

Numerous RCTs and meta-analyses support its efficacy in improving cognitive function and circulation. Studies also indicate potential benefits in reducing anxiety symptoms.

Preparation & Dosage

Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.

Nutritional Profile

- Contains flavonoids and terpenoids. - Rich in antioxidants. - Contains bilobalide and ginkgolides.

Reported Mechanism (Provisional)

Mechanism of Action

The standardized extract's flavonoid glycosides (quercetin, kaempferol) and terpene lactones (ginkgolides A, B, C and bilobalide) inhibit platelet-activating factor (PAF) and enhance nitric oxide synthase activity. This dual action reduces blood viscosity while promoting vasodilation through increased cGMP levels. The ginkgolides specifically antagonize PAF receptors, preventing excessive platelet aggregation and improving microcirculation.

Clinical Narrative (Provisional)

Multiple randomized controlled trials involving over 2,000 participants demonstrate ginkgo's cognitive benefits, with studies showing 7-12% improvements in memory tests and attention span over 12-24 weeks. A meta-analysis of 40 studies found significant improvements in claudication distance (walking ability) by an average of 34 meters. However, large-scale trials for dementia prevention have shown mixed results, with some studies finding no significant difference versus placebo in preventing cognitive decline.
