| Proanthocyanidins (PACs) are a class of highly potent polyphenol antioxidants found in American cranberry (Vaccinium macrocarpon). A-type proanthocyanidins (PACs), specifically Procyanidin A-2 dimer, are the key active compounds in cranberries responsible for preventing bacteria from adhering to the bladder and urinary tract walls. BL-DMAC method is a global gold-standard testing protocol used to quantify proanthocyanidins (PACs) in cranberry products. Developed by Brunswick Laboratories, BL-DMAC measures bioactive PACs and A-type PAC linked to urinary tract health, preventing overestimations seen in common UV testing methods.  BOTANICAL ORIGIN: Vaccinium macrocarponPLANT SOURCE: Fruits APPEARANCE: Brownish red to violet red powder AVAILABLE SPECIFICATIONS: Proanthocyanidins 2-30% / Proanthocyanidin-A 1-30% BL-DMAC ANALYSIS METHOD: BL-DMACCranberry Extract A-type Proanthocyanidin (distinct from B-type) Primary Applications UTI Prevention: Widely used to prevent recurrent UTIs by stopping bacterial adhesion in the urinary tract. Antibiotic Reduction: Used for long-term management to reduce reliance on antibiotics. Emerging Uses: Research highlights potential in modulating microbiomes, reducing biofilms, and supporting oral health or oncology studiesProduction process of Cranberry Extract A-type Proanthocyanidin: Freezing preparation -> Solvent Extraction -> Acidification -> Purification -> Resin Chromatography -> Concentration -> Spray drying -> Standardization & Quality Control -> Packaging |
