High Hyalplus is a sterile gel containing 20mg active ingredient, sodium hyaluronate, in 2ml of liquid. Used to treat people with painful knees due to osteoarthritis. Joints can change shape or swell up due to this condition and High HyalPlus helps to increase mobility and independence.. Although Sodium Hyaluronate is found naturally in the joints, as a lubricant and shock absorber, it can break down completely in the joints, making it painful and difficult to move.
