Proanthocyanidins are polyphenolic chemicals that inhibit pathogenic micro organism from attaching to the lining of the urinary tract. That anti-adhesion action is what makes cranberry extract clinically useful.
Our products are derived from real Vaccinium macrocarpon, using controlled methods. We don't use cheap fillers like grape seed or peanut skin extracts like the low grade products on the market.
HPLC fingerprinting is performed on each batch for botanical origin and batch-to-batch uniformity. Every gram is true cranberry power, not the inflated numbers you get with common UV testing procedures.
