ENDUR-FLEX® promotes joint health by nourishing your body’s production of proteoglycans, which are large molecules required to maintain, rebuild, and repair cartilage tissue and lubricate joints. 

Glucosamine and chondroitin sulfate are vital building blocks for proteoglycans. In joint cartilage, proteoglycans weave through the network of collagen where they attract and hold water. This ability to hold water is what maintains resilient, yet elastic, cartilage tissue. It also is critical to produce the viscous synovial fluid that lubricates and cushions your joints.*

• Easy-to-swallow tablets
• No salt, starch, preservatives, artificial color or flavorings
