UT Strength Pro is a formula to support urinary tract health in dogs. It can be used long term for dogs that are prone to urinary tract issues or crystals. D-Mannose, a naturally occurring simple sugar, removes harmful bacteria through elimination. UT Strength Pro also features N-acetyl glucosamine or NAG, an important form of glucosamine found in the body thats used for the production of glycoproteins. The glycoprotein layer in the mucosal lining of the urinary tract has a high content of NAG. This layer of mucosal cells is the protective barrier against acids and bacteria. GanedenBC30®, a patented probiotic backed by 17 clinical studies helps maintain microflora balance in the UT tract.
