Organic Ginkgo Biloba Extract

Also known as: Ginkgo, Maidenhair Tree, Ginkgo biloba

Overview

Ginkgo biloba is a tree native to China, renowned for its medicinal properties derived from its leaves. The extract is rich in flavonol glycosides, terpenoids (ginkgolides and bilobalides), and proanthocyanidins, contributing to its antioxidant and vasoactive effects. It is widely used as a herbal supplement to enhance cognitive function, improve memory, and support vascular health. Ginkgo biloba is characterized by its antioxidant and anti-inflammatory actions, making it a popular choice for managing conditions related to cognitive decline and circulatory issues. While extensive research exists, the quality of evidence varies, necessitating careful evaluation of study methodologies and outcomes. Ginkgo biloba supplements are available in various forms, including standardized extracts like Egb 761, ensuring consistent concentrations of active compounds.

Benefits

Ginkgo biloba has shown promise in improving cognitive function, particularly when combined with conventional treatments like donepezil in dementia patients. A meta-analysis indicated significant improvements in MMSE scores with combined treatment. Additionally, ginkgo biloba extract has demonstrated efficacy in reducing symptoms of generalized anxiety disorder, with notable response rates observed in high-dose groups. Furthermore, it may offer benefits for individuals with idiopathic pulmonary fibrosis by improving oxygen saturation and reducing hyaluronic acid levels. These benefits typically manifest after several weeks of consistent use, highlighting the importance of adherence to recommended dosages. While effect sizes vary, the consistent reporting of improvements in cognitive and anxiety-related outcomes underscores its potential therapeutic value.

How it works

Ginkgo biloba extract exerts its effects through multiple mechanisms. It enhances vascular health by promoting nitric oxide production, which improves blood flow, and by inhibiting platelet-activating factor, reducing the risk of blood clots. Additionally, it modulates neurotransmitter systems by inhibiting monoamine oxidase A, influencing the levels of dopamine, serotonin, and norepinephrine. These actions collectively contribute to its cognitive-enhancing and mood-regulating properties. The active components are absorbed into the bloodstream, interacting with the cardiovascular and nervous systems to produce these effects. Flavonoids and terpenoids, key constituents of Ginkgo biloba, are generally well-absorbed, facilitating their interaction with various molecular targets in the body.

Side effects

Ginkgo biloba is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects include gastrointestinal issues and headaches. Less common side effects are dizziness and allergic reactions. Severe allergic reactions are rare. Ginkgo biloba may interact with anticoagulants, increasing the risk of bleeding, and is contraindicated in pregnancy, breastfeeding, and individuals with bleeding disorders. Caution is advised in children and those with pre-existing medical conditions. Due to its potential to increase bleeding risk, it should be used with caution before surgical procedures. It is important to consult with a healthcare provider before starting ginkgo biloba, especially if taking other medications or having underlying health conditions.

Dosage

The minimum effective dose of Ginkgo biloba typically starts at 120 mg per day. Optimal dosage ranges are between 120-240 mg per day for cognitive benefits, with higher doses sometimes used for anxiety. It is generally recommended not to exceed 480 mg per day. Ginkgo biloba is best taken with meals to reduce gastrointestinal side effects. Standardized extracts, such as Egb 761, are preferred for consistency in active compound concentrations. Food intake can enhance the bioavailability of its active components. Consistency in timing and dosage is crucial for assessing its benefits over several weeks. Always consult with a healthcare provider to determine the appropriate dosage based on individual health needs and potential interactions with other medications.
