quality tier
n/a
elemental fraction
Typical standardization: Often a ratio (4:1 to 50:1) or a PAC percentage
Why this tier: The PAC-standardized extracts are what the dose-response UTI evidence is expressed in (PAC mg/day), but the labels' mg of extract cannot be converted to PAC mg without the declared PAC content, and no verified study ranks extract types.
