Ranking
Urinary tract supplements are mostly cranberry, D-mannose and herbs such as uva ursi, and the labels differ in one way that matters: whether they state the active content. Cranberry products in particular range from juice powder to extracts standardized for proanthocyanidins (PACs), the compounds studied for the urinary tract.
We ranked cranberry, D-mannose, uva ursi and urinary and bladder formulas sold on iHerb by label quality.

Every product is scored 0–100 from its label data in the NIH Dietary Supplement Label Database: dosage transparency (35 points - are amounts stated per ingredient, or hidden in a proprietary blend?), label completeness (25), formulation cleanliness (25 - fillers, dyes, titanium dioxide and other non-active ingredients) and ingredient profile (15). The Top 10 admits only products scoring 60 or higher; among those, products with a verified retail listing are shown first so the list is one you can act on. No brand can pay to be included or moved up.
Cranberry studies have often used products with about 36 mg of PACs per day; compare PAC content, not cranberry weight. D-mannose has been studied at about 2 g per day. Uva ursi should not be used for more than a short period.
Adults looking for a clearly labeled cranberry or D-mannose product. A suspected urinary tract infection needs medical care, not a supplement.
Cranberry with no stated PAC content, long-term uva ursi use, cranberry with warfarin, and products that claim to treat infections.
By proanthocyanidin (PAC) content per serving, ideally with the test method named. "Cranberry 500 mg" alone does not tell you how much of the studied compound you get.
No. Our ranking judges label quality. See a clinician for a suspected infection.
Products are ranked by SupplementScore, which evaluates label quality across four categories: dosage transparency (35 pts), label completeness (25 pts), formulation cleanliness (25 pts), and ingredient profile (15 pts). The score is based on data from the NIH Dietary Supplement Label Database, not marketing claims.
No. The SupplementScore measures label quality, how transparent, clean, and well-documented a product is. It does not measure clinical efficacy, bioavailability, or third-party testing. A higher score means better label practices, not guaranteed results.
We analyzed 1,254 urinary health products from the NIH DSLD database, which contains label data for over 116,000 dietary supplements sold in the United States.
