AZO

AZO receives a brand trust score of 57/100 in GoodSupp's independent analysis. Our research did not find independently verified third-party certifications for this brand. While this doesn't mean their products are low quality, third-party testing is considered a strong indicator of commitment to quality assurance. Note: AZO has 2 historical regulatory incidents on record. These are factored into the overall trust score and are detailed in the violation history section above.

GoodSupp's research did not find verified third-party testing certifications for AZO. Third-party testing by organizations like NSF International, USP, or Informed Sport is considered one of the strongest indicators of supplement quality. Without it, consumers must rely more heavily on the brand's own quality claims. This doesn't necessarily mean AZO's products are low quality, but it does mean there's less independent verification of their claims.

Based on GoodSupp's quality analysis, the highest-rated AZO supplements are: D-Mannose Gummies, Citrus Blast (score: 95/100); D-Mannose, Urinary Health (score: 95/100); Complete Feminine Balance®, Daily Probiotic (score: 64/100). These scores are calculated from ingredient quality, dosage adequacy, bioavailability, label transparency, and inactive ingredient safety. Scores can vary significantly across a brand's product line — a high brand trust score doesn't guarantee every individual product is top-quality.

AZO is headquartered in Cromwell, Connecticut, USA. They currently offer 22 products in their supplement lineup. Their official website is azoproducts.com. Manufacturing location may differ from corporate headquarters — look for GMP certification to verify manufacturing quality standards.
