Ginkgo Biloba Quality: Why It Matters
Ginkgo biloba is one of the most studied herbal supplements, traditionally associated with cognitive function and blood circulation. However, ginkgo biloba quality varies enormously on the market β non-standardised products may contain only a fraction of the active compounds. This guide covers what to look for on the label.
What to Look for on the Label
Standardised Extract vs Plant Powder
A quality ginkgo product must carry a note of "standardised extract" with the percentage of active compounds. The most widely used in clinical research is the EGb 761 extract, standardised for:
- Ginkgo flavone glycosides β to a controlled percentage
- Terpene lactones (ginkgolides A, B, C and bilobalide) β to a controlled percentage
Plant powders without standardisation have not been clinically tested and their bioavailability is unpredictable.
Ginkgolides: Why They Matter
Ginkgolides β particularly ginkgolide B β are pharmacologically active compounds associated with inhibiting platelet activating factor. These are the active compounds that distinguish a genuine ginkgo extract from low-quality powder.
MST Ginkgo Biloba 60caps is a standardised extract product available at maxfit.ee. Also worth considering is OstroVit Ginkgo Biloba Extract 50g β a powder form for those who want flexible dosing.
Form and Dose Markers
Doses and intake frequency used in clinical studies vary across research. If a doctor has made a recommendation, discuss it with them. The label must clearly state both the dose and the standardisation percentage β without this, the product's efficacy cannot be assessed.
Capsules are the preferred form with less contact with oxygen, protecting the active compounds. BIOTECHUSA Ginkgo Biloba 90tabs is a tablet form suitable for those who prefer a more budget-friendly option.
Third-Party Testing
As with all supplements, third-party certificates (NSF, Informed Sport, etc.) are the most reliable guarantees of product purity and content accuracy. With ginkgo, particularly important is:
- Ginkgol content: ginkgol is a toxic compound that must be below a certain level in extracts. Quality manufacturers test for this specifically.
- Heavy metals: plant products absorb metals from soil β testing should confirm safe levels.
Red Flags
| Characteristic | What It Means |
|---|---|
| No standardisation statement | Active compound content is uncertain |
| Very cheap "ginkgo extract" | Likely non-standardised |
| Ginkgolide percentage not stated | No quality control |
| Vague claims on the label | May indicate a poor quality product |
Value for Money
Ginkgo biloba extract is relatively affordable in the supplement world, but the difference in quality levels is large. Pay a little more for a standardised extract and avoid cheap products sold as plant powder. Browse the selection at maxfit.ee in the ginkgo biloba category.
Summary
The main criteria when choosing quality ginkgo biloba: standardised extract (ideally EGb 761 type), clear ginkgolide percentage, ginkgol content testing, and third-party certification.
FAQ
Is ginkgo biloba suitable alongside medications?
Ginkgo may affect blood clotting. If you take anticoagulants (such as warfarin), definitely consult a doctor before starting a ginkgo supplement.
How many weeks does ginkgo biloba need to be taken before noticing effects?
Most studies use periods of four to twelve weeks. Expecting immediate effects is unrealistic.
Is ginkgo biloba suitable for children?
Ginkgo biloba studies have been conducted mainly in adults. Ginkgo use in children is not recommended without medical advice.
