Product Description

ENDUR-FLEX® Glucosamine 500mg/Chondroitin 200mg (Sustained Release) is ideal for men and women who want to maintain optimal joint flexibility, comfort, and movement.*

ENDUR-FLEX® is specially formulated to provide glucosamine and chondroitin sulfate – two joint health nutrients backed by a large body of clinical research – in a unique sustained-release tablet for slow and steady nutrient release.

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

How can you tell it's working?

I have been using this product for many years. I still have pain in my finger joints. I can only guess that it would be worse if I weren't using this product.

I take one tablet with breakfast and another with dinner. Endur- Flex keeps my joints flexible and helps keep me active. I've taken it for years ever since I started having joint stiffness. It seems to work for me.
