L-(-)-Mannose is a naturally occurring sugar that plays a crucial role in various biological processes. This monosaccharide is recognized for its ability to support urinary tract health and is often utilized in dietary supplements aimed at preventing urinary tract infections (UTIs). Its unique structure allows it to inhibit the adhesion of certain bacteria to the urinary tract lining, making it a valuable ingredient in formulations designed for both preventive and therapeutic applications. Additionally, L-(-)-Mannose is gaining attention in the field of metabolic health, where it may contribute to improved insulin sensitivity and glucose metabolism, offering potential benefits for individuals managing diabetes.
