Ginkgo Biloba Powder
Also known as: Ginkgo, Ginkgo biloba leaf extract, Silver Apricot, Ginkgo biloba
Overview
Ginkgo biloba, one of the oldest living tree species, is native to China and is widely used in dietary supplements. Extracts from its leaves are acclaimed for their potential cognitive, cardiovascular, and anti-inflammatory benefits. The key bioactive components include flavonoids, terpenoids, and ginkgolides, which confer antioxidant and anti-inflammatory properties. Research has delved into various health benefits including memory enhancement, improved blood circulation, and the potential treatment for conditions like tinnitus, dementia, and type 2 diabetes. Various studies, such as randomized controlled trials and systematic reviews, support the safety and efficacy of Ginkgo biloba extracts, especially in older adults experiencing cognitive decline, although the quality of evidence remains mixed for different health claims.
Benefits
Ginkgo biloba is particularly recognized for enhancing cognitive function, with strong evidence for its support among elderly individuals suffering from dementia. A meta-analysis indicates significant cognitive improvement when Ginkgo is administered alongside donepezil. Additionally, Ginkgo biloba shows promise in improving blood metabolism in patients with type 2 diabetes, hinting at positive trends in hemorheology and lipid profiles, although the clinical significance of these findings remains uncertain. There is also mild evidence of reductions in depressive symptoms and tinnitus within certain demographic groups, particularly those with vascular dementia. The evidence is most compelling for older adults experiencing cognitive decline, indicating a potential role as a cognitive enhancer.
How it works
Ginkgo biloba exerts its effects primarily through its robust antioxidant properties, shielding cells from oxidative damage while enhancing neuronal plasticity. It actively modulates oxidative stress and inflammatory responses involving cytokines such as TNF-α, IL-6, and IL-1β. The active compounds, particularly flavonoids and ginkgolides, safeguard neurons from damage and promote cerebral blood circulation, which collectively supports enhanced cognitive function and overall brain health.
Side effects
Ginkgo biloba is generally regarded as safe when used appropriately; however, there are several risks associated with its use. Common side effects reported by more than 5% of users include gastrointestinal upset, headaches, and allergic reactions. Less common side effects (1-5%) may encompass dizziness, nausea, and an increased risk of bleeding, particularly in individuals taking anticoagulants. Rare but serious adverse events (less than 1%) can include seizures and significant bleeding, although these occurrences are uncommon. Caution is advised for individuals with bleeding disorders or those on blood thinners due to the heightened risk of bleeding. Additionally, pregnant and breastfeeding women should take precautions owing to limited safety data in these populations.
Dosage
The standard recommended dosage of Ginkgo biloba extracts typically falls between 120 mg to 240 mg per day, standardized to deliver 24% flavone glycosides and 6% terpene lactones. For cognitive enhancement, a daily dosage of 240 mg is commonly advised, especially when used alongside cognitive enhancers like donepezil. Higher dosages exist but often lack comprehensive research support, warranting cautious use. While the timing for doses is flexible, maintaining a consistent daily intake is critical to achieving desired benefits. Standardized extracts are preferred to ensure the presence of consistent bioactive compounds, and taking the supplement with food may enhance absorption.
