Today, it is one of the most popular herbal supplements worldwide, known for its potential benefits in cognitive enhancement, immune modulation, and metabolic health. This article explores the various aspects of Ginkgo biloba supplements, including their active components, health benefits, and potential risks.
Active Components
The primary active components of Ginkgo biloba are terpene lactones and flavonoids. These compounds are responsible for the herb’s therapeutic effects. A study developed a fingerprint profile method using capillary HPLC/MS to identify over 70 components in Ginkgo biloba products, allowing for simultaneous detection of flavonoids and terpene lactones1. This method is crucial for quality control and ensuring the consistency of Ginkgo biloba supplements.
Health Benefits
Cognitive Enhancement
Ginkgo biloba is widely used for its potential to improve cognitive function and treat dementia. A review of clinical trials indicated that Ginkgo biloba extracts might offer some benefits in cognitive performance and activities of daily living, particularly at doses greater than 200 mg/day5. However, the evidence is inconsistent, and more rigorous studies are needed to confirm these effects.
Immune Modulation
Several studies have demonstrated the immune-boosting properties of Ginkgo biloba. For instance, dietary supplementation with Ginkgo biloba leaf extract (GBLE) in common carp significantly enhanced growth performance, immune responses, and survival rates after infection with Aeromonas hydrophila2. Similar benefits were observed in hybrid groupers and Nile tilapia, where GBLE improved immune function, antioxidant status, and intestinal health3 4.
Metabolic Health
Ginkgo biloba has shown promise in managing metabolic syndrome, which includes conditions like obesity, hypertension, and dyslipidemia. The herb’s major compounds, such as bilobalide and ginkgolides, have antidiabetic, antihypertensive, and antilipidemic properties6. However, more clinical trials are needed to fully understand its efficacy and safety in treating metabolic syndrome.
Physical Performance
A study on physically active men found that six weeks of Ginkgo biloba supplementation marginally improved aerobic performance and blood antioxidant capacity. The supplementation also increased exercise-induced production of brain-derived neurotrophic factor (BDNF), suggesting potential neuroprotective effects7.
Quality Control and Authentication
Ensuring the authenticity and quality of Ginkgo biloba supplements is crucial. A DNA mini-barcode assay was developed to authenticate Ginkgo biloba in herbal dietary supplements, revealing that some products on the market were mislabeled or contained fillers without any detectable Ginkgo biloba DNA9. This highlights the need for stringent quality control measures in the supplement industry.
Potential Risks
While Ginkgo biloba is generally considered safe, there are potential risks associated with its use. A study evaluating Ginkgo biloba leaf extract drinks found that the levels of certain compounds, such as ginkgolic acids, exceeded acceptable limits, posing potential health risks10. Therefore, consumers should be cautious and choose products from reputable sources.
Conclusion
Ginkgo biloba supplements offer a range of potential health benefits, from cognitive enhancement to immune modulation and metabolic health. However, the quality and authenticity of these supplements can vary, and there are potential risks associated with their use. Further research and stringent quality control are essential to ensure the safety and efficacy of Ginkgo biloba supplements.
