This **cranberry** extract delivers 500mg of Cran-Max per capsule, right at the minimum daily dose studied for lowering your risk of recurrent urinary tract infections if you're prone to them. The active compounds are proanthocyanidins (PACs), which stop bacteria from sticking to the bladder wall — a 2023 Cochrane review backs cranberry for cutting how often recurrent UTIs come back.
The catch is that the clinical effect tracks PAC content, which trials often standardize to around 36mg per day. This label doesn't state the PAC level, so you can't confirm it reaches that threshold, and some studies used higher doses up to 1,500mg.
One thing to be clear on: cranberry here is for prevention, not treatment. It won't clear an active infection — that needs antibiotics from a doctor.
