UT Answer is a unique natural blend of cranberry, D-mannose, caprylic acid, and Uva Ursi. All of these ingredients combine to support healthy urinary tract function*. Cranberry has been used for centuries to support urinary tract health. These bright red tart berries contain a specific type of proanthocyanidin(PAC) referred to as A-type, which has a unique ability to interfere with anything that tends to adhere to the bladder wall. Modern science discovered that D-Mannose acts as a decoy sugar, attracting invaders away from the bladder lining.
