Urinary health and the immune system are closely connected, and both are crucial for overall wellbeing. The urinary tract serves as a frontline defense against threats, and it relies on a vigilant immune system to function effectively. The immune system detects and combats pathogens that attempt to infiltrate the urinary system.*³ Supporting your immune system is, therefore, vital for your urinary health, and supporting both systems is crucial to your overall health and wellness.*
