Formulator & Buyer FAQ

01. What are Proanthocyanidins (OPCs)?
Oligomeric Proanthocyanidins (OPCs) are a class of polyphenolic compounds found abundantly in pine bark. They are highly bioavailable flavonoids known for their intense antioxidant capacity. They protect collagen and elastin in the skin and promote healthy nitric oxide levels for improved blood vessel function.
02. Why is UV testing used for this product instead of HPLC?
Proanthocyanidins are a complex mixture of oligomers and polymers of different sizes rather than a single distinct molecule. Ultraviolet Spectroscopy (UV) is the industry-standard and most scientifically accurate method to measure the total aggregate proanthocyanidin content (95%) in pine bark and grape seed extracts.
03. Is this powder soluble in water?
Yes, Pine Bark Extract (95% OPC) exhibits excellent solubility in water and ethanol. This makes it highly versatile, allowing for seamless formulation into clear liquid supplements, functional beverages, and water-based cosmetic serums. Note that it will impart a reddish-brown hue to liquid formulas.
04. Can you supply the COA and Heavy Metal tests for bulk orders?
Absolutely. As a direct factory supplier, every commercial batch is rigorously tested. We provide a comprehensive Certificate of Analysis (COA) that includes UV assay results, moisture content, ash, microbiological limits, and heavy metal screening (Pb, As, Hg, Cd) compliant with international supplement standards.
