UVA URSI 650 is a unique botanical blend formulated to promote a healthy urinary tract. One of the key ingredients in UVA URSI 650 is uva ursi extract which is standardized to contain 20% arbutin. Arbutin, particularly when combined with berberine sulfate, provides a powerful combination to help maintain healthy microbial balance in the urinary tract and bladder. In addition, marshmallow root soothes bladder and urinary tract discomfort. Celery seed extract and bladderwrack leaf are also included in UVA URSI 650 for their ability to act as a natural diuretic.
