Ginkgo einfach erklärt – Wirkung und Anwendungsgebiete im Überblick
Ginkgo biloba zählt zu den ältesten Baumarten der Welt und wird in der traditionellen chinesischen Medizin bereits seit über 2.000 Jahren geschätzt. Heute findet standardisierter Ginkgo-Blattextrakt vor allem Verwendung in Nahrungsergänzungsmitteln und pflanzlichen Präparaten. Doch was ist Ginkgo und wofür wird er eingesetzt?
Als Anbieter hochwertiger Naturprodukte und Nahrungsergänzungsmittel beschäftigen wir uns bei Heilnatura intensiv mit den Themen Mikronährstoffe, Pflanzenextrakte und Wohlbefinden. In diesem Ratgeber erfahren Sie, welche wissenschaftlichen Erkenntnisse zur Wirkung von Ginkgo-Kapseln und -Tabletten vorliegen, welche Anwendungsgebiete häufig diskutiert werden und worauf Sie bei Qualität, Einnahme und Sicherheit achten sollten.
What Is Ginkgo Biloba?
Ginkgo is an ancient tree commonly found in Asian temple gardens and parks and is often referred to as a living fossil. It belongs to the Ginkgoaceae family and is grown both as an ornamental tree and traditionally used in Chinese medicine.
Today, research focuses primarily on extracts from the leaves of the ginkgo tree. These contain various plant compounds, including ginkgolides and bilobalide. For dietary supplements and herbal preparations, the leaves are processed into an extract, with standardized dry extracts containing particularly high concentrations of these compounds.
Effects of Ginkgo – What Is Ginkgo Good For?
The effects of ginkgo tablets and capsules have been studied primarily in relation to memory, brain function and cognitive impairment, concentration, tinnitus, and circulatory disorders. The following sections explain the scientific evidence currently available for each area of use and how it should be interpreted.
Ginkgo for Memory Problems and Dementia
The effects of Ginkgo biloba have been studied in connection with memory problems, forgetfulness, and certain forms of dementia. Research has focused particularly on Alzheimer’s disease, the most common form of dementia. However, it is important to distinguish between occasional forgetfulness in everyday life and a diagnosed form of dementia. Persistent or worsening memory problems in particular should be evaluated by a doctor.
The German S3 guideline on dementia refers to the standardized special extract EGb 761. For people with mild to moderate dementia, this extract may be considered at a dosage of 240 mg per day.
However, this recommendation applies exclusively to the specific extract studied and is not a substitute for medical diagnosis or treatment in accordance with clinical guidelines. It cannot be interpreted as a general recommendation for ginkgo to treat age-related forgetfulness or prevent dementia.
Ginkgo for Concentration and Mental Performance
Ginkgo biloba is frequently discussed in connection with concentration, attention, and mental performance and is therefore often included in dietary supplements for enhanced performance.
Numerous studies have investigated whether the plant extract can support cognitive function. However, the research findings to date in healthy adults are inconclusive, so no general conclusions about its benefits can currently be drawn.
Regardless of this, mental performance is influenced by many factors. Getting enough sleep, exercising regularly, eating a balanced diet, and managing stress effectively all play an important role. If problems with concentration or mental fatigue persist, medical evaluation is recommended to identify possible underlying causes.
If you would like to supplement your daily diet with selected nutrients, you can also find focus capsules in our range, which contain Ginkgo biloba extract as well as a variety of antioxidant plant extracts and micronutrients. We also offer additional antioxidant supplements to complement your nutrient intake.
Ginkgo for Tinnitus and Dizziness
Ginkgo biloba is frequently discussed in connection with tinnitus and dizziness. Recent individual studies have shown positive trends for standardized special extracts (such as EGb 761), particularly when tinnitus is acute or accompanied by significant stress and anxiety. However, it is not possible to make a general statement about whether or to what extent it is beneficial. The results of scientific studies vary depending on the diagnosis, the ginkgo preparation used, and the study design.
If you would like to learn more about the current state of research, read our guide to Ginkgo biloba for tinnitus. Newly occurring tinnitus, dizziness, or neurological symptoms should always be evaluated by a doctor to rule out possible underlying causes and initiate appropriate treatment.
If you would like to supplement your diet, you can find our tinnitus capsules in our range, featuring a carefully formulated combination of Ginkgo biloba extract, SAMe, vitamin D3, and calcium.
Vitamin D3 contributes to the normal function of the immune system, while calcium contributes, among other things, to normal neurotransmission. Dietary supplements can be a useful addition to a balanced diet, but they are not a substitute for medical diagnosis or treatment.
Ginkgo for Circulatory Problems
Some scientific studies suggest that Ginkgo biloba may improve blood flow properties, including in small blood vessels. This effect on circulation has primarily been observed with specific standardized extracts. However, whether taking dietary supplements containing ginkgo extract can actually help with circulatory problems is still being investigated.
Numerous studies are also currently investigating the effects of nattokinase on blood circulation. If you are interested in the current scientific evidence on the effects of nattokinase, we recommend reading our dedicated blog article.
How to Use Ginkgo – Dosage and Duration
The appropriate dose of Ginkgo biloba depends on factors such as the specific product and its intended use. In clinical studies, standardized ginkgo extracts have often been taken over an extended period of time.
As the composition and concentration of active compounds can vary between products, you should always follow the recommended dosage for the specific product. A higher dose does not automatically result in greater effectiveness and should not be taken without professional guidance.
What to Look for When Buying Ginkgo
When buying ginkgo products, it is also worth looking at the quality of the extract used and the manufacturer’s instructions for recommended use. You should also look for transparent information from the manufacturer regarding the composition, dosage, and active compounds contained in the product.
When selecting our raw materials at Heilnatura, we work exclusively with suppliers who provide us with complete product specifications, certificates of analysis, and documentation confirming the traceability of the raw materials used.
Side Effects and Interactions
Ginkgo biloba is generally considered well tolerated when used as directed. However, as with many herbal preparations or dietary supplements, side effects may occur. These can include gastrointestinal discomfort, headaches, or, in rare cases, allergic skin reactions.
Particular caution is advised when taking blood-thinning medications at the same time, as ginkgo may increase the risk of bleeding. If you are scheduled for surgery, you should also discuss taking ginkgo with your doctor and stop taking it in good time before the procedure. People with epilepsy or a history of seizures should also take ginkgo only after consulting a doctor.
There is currently only limited safety data available for pregnant or breastfeeding women, as well as children and adolescents. Ginkgo should therefore only be taken during these stages of life on the advice of a healthcare professional. In addition, the seeds of the ginkgo tree should not be consumed, as they may contain substances that are harmful to health.
