VetriScience® Laboratories UT Strength Canine is a formula to support urinary tract health in dogs. It can be used long term for those dogs that are prone to urinary tract issues or crystals. UT Strength contains D-Mannose, a naturally occurring simple sugar that removes harmful bacteria by attachment and voiding. Its absorbed eight times slower than glucose is not converted to glycogen or stored in the liver when ingested. Rather, D-Mannose goes directly into the blood stream from the kidneys to the bladder. UT Strength also features N-acetyl glucosamine or NAG, an important form of glucosamine found in the body. It is the form that is 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.
