Vivaldis Cranbact Capsules are a premium, professional veterinary urological supplement scientifically formulated to maintain bladder health and support urinary tract functionality in both dogs and cats. Powered by VitaCran, a highly concentrated, freeze-dried cranberry extract, this supplement delivers a potent dose of natural Proanthocyanidins (PACs) and Quinic Acid. Rather than acting as a chemical antibiotic, Cranbact works via a mechanical anti-adherence mechanism—it forms a protective barrier that physically prevents pathogenic bacteria (like E. coli) from clinging to the bladder and urinary tract walls. This allows harmful microbes to be naturally flushed out during urination, making it an excellent, drug-free adjunctive therapy for active Urinary Tract Infections (UTIs) and a proven prophylactic against chronic, recurrent urinary tract complications.
