Take four (4) capsules daily for focused urinary tract, bladder, and kidney support.*

Due to inventory-related issues from our manufacturer, some of our blue product caps have been replaced with a temporary white cap. Our traditional blue cap will return soon! In the meantime, rest assured knowing our products contain the same great formula you know and love.
