Products Description
Wellgreen's Pine Bark Extract Powder is a premium, standardized botanical ingredient derived from the pristine bark of Pinus massoniana Lamb.
Renowned as nature's antioxidant powerhouse, this extract is highly concentrated with Low-Molecular-Weight Oligomeric Proanthocyanidins (OPCs), offering an antioxidant density significantly superior to Vitamin E and Vitamin C.
At Wellgreen, we utilize advanced membrane filtration and low-temperature water-ethanol extraction technology to preserve the delicate polyphenolic matrix. By avoiding harsh chemical solvents, we deliver a clean-label, highly bioavailable powder that integrates seamlessly into downstream formulations. Whether you are developing high-end beauty-from-within capsules, cardiovascular wellness supplements, or functional animal nutrition, our standardized 95% OPC powder guarantees batch-to-batch consistency and strict global regulatory compliance.

FAQ
Q: Why is your 95% Proanthocyanidins specification tested via UV rather than HPLC?
A: In global botanical commerce, total Proanthocyanidins (PACs/OPCs) consist of complex polymer chains that cannot be fully separated or accurately quantified as a single 95% peak on HPLC. UV (or Bate-Smith) is the scientifically correct method for absolute quantification of total OPC density, whereas HPLC is used as a qualitative tool to verify individual monomer fingerprints.
Q: Does your Pine Bark Extract leave a residue or cloudiness in water?
A: Our extract has excellent dispersibility. While it retains its natural, rich botanical color, it dissolves completely in water-based applications without leaving gritty sediments, making it suitable for functional liquids.
Q: Is Wellgreen Pine Bark Extract a clean-label ingredient?
A: Yes. We use only food-grade ethanol and purified water during processing. No artificial carriers, fillers, or chemical preservatives are added, fully meeting clean-label formulation trends.
Q: Can I request documentation for specific regulatory entry?
A: Absolutely. We provide a comprehensive documentation packet upon request, including the Certificate of Analysis (COA), Allergen Statements, Non-Irradiation Certificates, MSDS, and third-party heavy metal assay data.
