Vestige Cranberry is a unique combination of two powerful ingredients, cranberry extract and D-Mannose that promotes maintenance of healthy urinary tract. Cranberry is a native evergreen shrub that grows throughout North America. Historically, cranberry fruits or leaves were used for bladder, stomach, and liver disorders, as well as diabetes, wounds, and other conditions. Today, cranberry is used as a dietary supplement primarily for UTIs. Their citric acid content helps to manage bladder complications. D-Mannose inhibits a certain kind of bacteria to adhere to the walls of the urinary tract, thus preventing recurrence. It also acts as a prebiotic that helps to promote ‘good’ bacteria in the digestive system.
