AI-Powered supplier vetting

SummaryHunan Sunfull Bio-Tech Co., Ltd. is a China-based factory established in 2008, with 60 employees and three production lines. It supplies botanical, herbal, fruit, and plant extracts for health, food, chemical, agricultural, cosmetic, and pharmaceutical applications. The company reports ISO9001:2015 certification and additional certifications or standards, while another description lists ISO22000, Kosher, HALAL, and HACCP. It has seven R&D engineers, fewer than five quality-control staff, and self-operated import/export rights. Export sales reportedly account for 71%–90% of total sales, indicating international trading experience. Evidence confirms product examples including turmeric extract and cordyceps mycelium extract, plus one associated Vietnamese buyer transaction. However, the provided information does not establish after-sales procedures, financial credibility, customization services, or a broad customer portfolio.

Supplier typeThe supplier is identified as a factory and limited company based in Changsha, Hunan, China, with 60 employees, a 974.0 m² manufacturing plant, and three production lines. Its stated business covers botanical extracts, herbal extracts, fruit powders, plant powders, and chemicals.

CertificationsThe supplier explicitly reports ISO9001:2015 certification. A separate company description also lists ISO22000, Kosher, HALAL, and HACCP, although the provided slices do not include certificate numbers, validity dates, or issuing-body details.

R&D capabilityThe supplier states that it specializes in R&D and production of green tea and botanical extracts, and reports seven R&D engineers. This supports an established R&D function, but no evidence quantifies new-product development, patents, laboratories, or recent innovations.

Production capacityThe supplier reports a 974.0 m² manufacturing plant, three production lines, and products including turmeric extract and cordyceps mycelium extract. The listed product batches and stated manufacturing activity support actual production capability, though capacity details beyond the reported output range are limited.

Client casesThe evidence includes product records for turmeric extract and cordyceps mycelium extract and identifies one Vietnamese buyer associated with one recorded transaction. This confirms at least one documented buyer connection, but it does not establish a broad or independently validated customer case history.

Product Q&A

Q:What is the significance of the 5:1 extraction ratio?

The 5:1 ratio indicates that 5 kilograms of premium St. John's Wort flowering tops are concentrated to produce 1 kilogram of finished extract powder. This process enriches the bioactive compounds while maintaining the natural phytocomplex balance.

Q:Is this extract standardized for hypericin content?

While this is a full-spectrum 5:1 extract preserving the complete natural profile, we can provide extracts standardized to specific hypericin levels (typically 0.3%) upon request. Our standard 5:1 extract contains the natural ratio of compounds as found in the plant.

Q:What safety precautions should be considered when formulating with St. John's Wort?

St. John's Wort may interact with certain medications including antidepressants, birth control pills, and blood thinners.

Q:Can this extract be used in daytime formulations given its potential calming effects?

While St. John's Wort supports emotional balance, it typically doesn't cause drowsiness when used at recommended doses. Many users take it during daytime hours.

Q:What is the recommended dosage in finished products?

Typical clinical studies use 300-900 mg daily of standardized extract. For our 5:1 extract, recommended usage ranges from 200-500 mg per serving depending on the desired potency. Final dosing should comply with regional regulations.
