Organic Ginkgo Leaf

Also known as: Ginkgo, Maidenhair Tree, GBE, *Ginkgo biloba*, Ginkgo biloba

Overview

*Ginkgo biloba*, commonly known as Ginkgo or Maidenhair Tree, is a tree native to China, and its leaves are used to produce herbal supplements. The leaves are rich in flavonoids and terpenoids, which are believed to be responsible for its beneficial effects. Ginkgo supplements are frequently used to improve memory, cognitive function, and cardiovascular health. It is known for its antioxidant properties and potential anti-inflammatory effects. Extensive research exists, including numerous systematic reviews and meta-analyses, though the quality of available evidence varies, with some studies showing significant benefits while others report mixed results. Ginkgo is available in various forms, including capsules, tablets, and liquid extracts, with standardized extracts being preferred for consistency.

Benefits

Ginkgo biloba extract (GBE) has demonstrated potential benefits in several areas. It has been shown to improve cognitive function in patients with dementia and schizophrenia, supported by systematic reviews and meta-analyses. Additionally, GBE may improve respiratory function in idiopathic pulmonary fibrosis (IPF) by enhancing lung capacity and reducing inflammation markers. Some research suggests potential benefits as an adjunct therapy for diabetic kidney disease, though further research is needed. These benefits are particularly relevant for older adults with cognitive decline and patients with IPF. The effect sizes vary across studies, but significant improvements are often reported in cognitive and respiratory functions, typically observed within several weeks to months of consistent use.

How it works

Ginkgo biloba's mechanism of action involves multiple biological pathways. It exhibits antioxidant and anti-inflammatory effects, contributing to its potential neuroprotective properties. The flavonoids and terpenoids in GBE interact with various cellular pathways, influencing cardiovascular, respiratory, and central nervous systems. These compounds may enhance blood flow, reduce oxidative stress, and modulate inflammatory responses. The absorption and bioavailability of Ginkgo biloba can vary based on the extract formulation and individual metabolism, affecting the extent to which these mechanisms are activated.

Side effects

Ginkgo biloba is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects (occurring in more than 5% of users) include gastrointestinal upset and headache. Uncommon side effects (1-5%) may include dizziness and allergic reactions. Rare side effects (less than 1%) involve bleeding risks due to its antiplatelet effects. Ginkgo biloba may interact with anticoagulants, diabetes medications, and certain antidepressants, potentially altering their effectiveness or increasing the risk of adverse effects. It is contraindicated in pregnancy, breastfeeding, and individuals with certain bleeding disorders. Caution is advised in patients with bleeding risks or those taking anticoagulant medications. Due to potential interactions, it's crucial to consult with a healthcare provider before starting Ginkgo biloba, especially if you have pre-existing conditions or are taking other medications.

Dosage

The typical minimum effective dose of Ginkgo biloba starts at 120 mg per day of a standardized extract. Optimal dosage ranges are generally between 120-240 mg per day, with a maximum safe dose not exceeding 480 mg per day. It is best taken with meals to reduce gastrointestinal side effects. Standardized extracts are preferred to ensure consistency in active compound concentrations. Bioavailability may be enhanced with food intake. While no specific cofactors are required, consistent daily use is recommended to observe potential benefits. Always consult with a healthcare provider to determine the appropriate dosage based on individual health status and specific needs.
