Supporting Canine and Feline Urinary Health


New look, same trusted Protexin Veterinary products.



CystoPro contains an active ingredient derived from cranberries. This active ingredient is a class of antioxidants called Proanthocyanidins (PACs).  CystoPro also contains probiotics, prebiotics and N-acetyl D-glucosamine.



  • Proanthocyanidins (Type A PACs)
    Proanthocyanidins are naturally occurring powerful antioxidants extracted from the North American cranberry.  Type A PACs have an anti-adhesion affect, this means they help to reduce the ability of certain bacteria to attach to the bladder lining.
  • Probiotic
    The EU-registered strain Enterococcus faecium (DSM 10663/ NCIMB 10415) 4b1707 acts to reduce pathogenic bacteria within the gastrointestinal tract and the faeces thereby limiting bacterial colonisation of the perineum.
  • Mannan-oligosaccharide
    Created from purified yeast cell walls, Mannan-oligosaccharide (MOS), binds to receptors on bacterial fimbriae which prevents attachment to epithelial cells. MOS is commonly used as a prebiotic to support intestinal microflora.
  • N-acetyl D-glucosamine
    N-acetyl D-glucosamine is a precursor to Chondroitin sulphate and Keratin sulphate which make up the Glycosaminoglycan (GAG) layer that lines and protects the sensitive bladder urothelium. A strong, resilient GAG layer prevents bacteria from adhering to the urothelial cells.
  • Artificial Chicken Flavour
    To improve palatability and compliance.

CystoPro is available in boxes of 30 and 120 capsules.
