Frequently Asked Questions
What is Chilean Cranberry?
Chilean Cranberry is a tart berry from the Patagonia region, prized for its high concentration of proanthocyanidins (PACs). These compounds are clinically shown to support urinary tract health by preventing bacterial adhesion.
How much cranberry extract should I take for UTI prevention?
For prevention, clinical studies support a daily dose of extract that provides at least 36 mg of A-type proanthocyanidins (PACs). This typically corresponds to 500-1000 mg of a quality standardized extract.
Can I just drink cranberry juice instead of taking an extract?
Most commercial cranberry juices are high in sugar and contain insufficient amounts of the active PACs to be effective for UTI prevention. A standardized extract provides a concentrated, therapeutic dose without the added sugar.
