Taken from their site "Chondroitin and Glucosamine are produced naturally by the body and aid in repair and maintenance of the joint tissue. Joint cartilage is not directly connected to any blood vessels so; all of the nutrients that the cartilage needs for good health have to be small enough to pass through cellular walls to benefit the joint tissue.
Cortaflex was formulated around the theory that small molecules are more likely to be absorbed through cellular walls. Therefore, Cortaflex contains the micro sized key active isolates of Chondroitin and Glucosamine, providing the body with both the building blocks and the stimulus for its own production of Chondroitin and Glucosamine."
Global Herbs do "Movefree". As it's a herbal supplement, I don't think it contains glucosamine but a quick phonecall to their helpline would confirm this. I've found all their products that I've used to be very good.
