Bulk Ginkgo Biloba Extract for Cognitive Health & Cardiovascular Support

Q1: How do you prevent Rutin adulteration in your Ginkgo Biloba Extract?

A: Adulteration with cheap flavonoids like Rutin has been an industry issue. However, Purecium strictly adheres to USP and ChP standards, utilizing advanced HPLC testing with precise Rutin limit values to guarantee our extract is 100% authentic and economically viable without adulteration.

Q2: What is the Ginkgolic acid limit in your extract?

A: Ginkgolic acids are potential allergens. We utilize advanced purification techniques to strictly control Ginkgolic acid levels to ≤5 ppm, fully complying with rigorous USP36 and EP8.0 safety standards.

Q3: Are the Ginkgo leaves sourced from endangered wild trees?

A: Absolutely not. Our Ginkgo leaves are sourced entirely from cultivated, sustainably managed, and government-registered plantations. No wild resources are ever depleted for our extraction processes.

Q4: Is there a tree age requirement for the leaves you extract from?

A: Yes. We extract exclusively from young Ginkgo trees aged 1–5 years. Active components, particularly flavonoid glycosides and quercetin, are significantly higher in younger trees before biosynthesis genes downregulate with age.

Q5: Do you sell finished Ginkgo products or offer OEM services?

A: Purecium strictly supplies bulk raw ingredients to B2B clients and does not sell finished retail products. However, we partner with certified CDMOs to facilitate end-to-end white-label services for tablets, hard/soft capsules, and gummies.

Q6: What is the regulatory status of Ginkgo Biloba Extract in the US and EU?

A: In the United States, it is fully compliant as an Old Dietary Ingredient (ODI). In Europe, standard Ginkgo extracts are recognized traditionally and are not subject to pre-market authorization under the Novel Food Regulation (EU) 2015/2283.

Q7: What is your Minimum Order Quantity (MOQ) and packaging standard?

A: Our MOQ is 25 kg. The powder is packaged in industrial drums (40x40x50cm) weighing 25kg net (28kg gross).

Q8: What are the physical characteristics of the extract?

A: It presents as a brownish-yellow powder, finely milled to a standard 80-mesh size, ensuring excellent flowability for supplement manufacturing.

Q9: What are your shipping options and lead times?

A: For clients in the US, Canada, and Mexico, we offer rapid 2-day pickup from our US warehouses. All other global destinations are served directly from our China facilities, with dispatch within one week.

A: Yes, we provide comprehensive technical dossiers, including both accelerated and long-term stability test data, to support your R&D and QA teams.
