We provide goods that satisfy global regulatory standards thanks to automated production lines and stringent quality control procedures. Available in 20–25 kg drums or 1–10 kg foil packs; samples are supplied; shipment occurs three days following payment confirmation.

Product Specifications

Mechanism of Action & Biological Activities

With multiple therapeutic pathways, Polydatin is a powerful stilbenoid polyphenol. Its glucose component, in contrast to resveratrol, permits active transport absorption, leading to enhanced serum concentration and prolonged release patterns.

Its three main mechanisms are beneficial to your formulations. By preventing NF-κB activation and lowering the expression of pro-inflammatory cytokines, it first modifies inflammatory pathways. Second, by directly scavenging free radicals and upregulating endogenous antioxidant enzymes, it offers antioxidant protection. Third, it protects healthy tissue while controlling apoptotic pathways in injured cells.

Studies show therapeutic potential in hepatic support, neuroprotection, cardiovascular protection, and anti-diabetic applications. It is useful for treating disorders related to oxidative stress and ischemia-reperfusion injury because of its anti-inflammatory and anti-apoptotic properties.

Primary Applications Across Industries

Pharmaceutical API Development: The product can be added to cardiovascular formulations that aim to improve microcirculation and decrease platelet aggregation. In clinical contexts, it helps the control of lipid metabolism and safeguards cardiomyocytes during ischemia episodes.

Advanced Cosmeceutical Formulations: The dual effect of polydatin gives your anti-aging and skin-brightening products a competitive edge. It shields fibroblasts from oxidative damage and UV-induced photoaging while more successfully inhibiting tyrosinase activity than kojic acid.

Bioavailable Nutraceutical Supplements: You can use the product as a "slow-release resveratrol" in your supplement formulas. It is broken down into resveratrol by intestinal β-glucosidase, which results in long-lasting pharmacokinetic profiles without problems with fast metabolism.

Functional Beverages: Clear liquid formulations in health tonics are made possible by its exceptional water solubility. Pasteurization and the fluctuating pH levels common in beverage manufacturing preserve the compound's bioactivity.​​​​​​​

Quality Assurance & Manufacturing Excellence

Automated extraction and purification processes are used in our GMP-compliant production plant to guaranty a minimum purity of 98%. Verification of raw materials, in-process monitoring, and testing of the finished product utilizing HPLC, UV-Vis spectroscopy, and microbiological examination are all part of multi-stage quality control.

Each production batch is subjected to stability assessment, pesticide residue testing, and heavy metal screening. With every shipment, you receive thorough Certificates of Analysis that attest to your adherence to international pharmacopeia standards.

From verified botanical sources to the delivery of the final product, our quality control system tracks raw materials. Polydatin stability is maintained during delivery to your location by nitrogen-flushed packing and temperature-controlled storage.

Frequently Asked Questions

Q: Why is polydatin more bioavailable than resveratrol?

A: Compared to resveratrol's passive diffusion, the glucose moiety permits active absorption through intestinal SGLT1 transporters, leading to higher serum concentrations and slower metabolism.

Q: Can polydatin be used in liquid cosmetic formulations?

A: It is perfect for serums, essences, and aqueous-based anti-aging treatments because to its water solubility and resilience against UV destruction.

Q: What paperwork do you include with shipments?

A: A Certificate of Analysis, MSDS, third-party test results, and certification paperwork (ISO, HALAL, KOSHER) for customs clearance are included with every order.

Q: Can you provide polydatin for use in clinical trials?

A: Definitely. For investigational novel medication applications, we offer GMP-grade material with complete traceability documentation and stability data.

Q: What is the minimum order quantity that you accept?

A: To support your pilot batches, we accept orders as small as 1 kg, and volume pricing is available for manufacturing on a commercial scale.
