Hyaluronic acid is a molecule found naturally throughout the human body. It is an important component of joint fluid, called synovial fluid, which provides lubrication and cushioning for normal, healthy knees.

When you have osteoarthritis of the knee, the hyaluronic acid breaks down and becomes diluted, reducing its natural elastic properties, which can further degrade cartilage tissue and cause increased joint pain.28

Administered as a series of 3 to 5 injections directly into the knee, SUPARTZ FX works as a viscosupplement, increasing the levels of healthy hyaluronic acid in the affected joint.42 The hyaluronic acid in SUPARTZ FX has the same composition as the natural hyaluronic acid your body produces, to safely reduce joint pain and stiffness, while restoring the protective benefits of lubrication and shock absorption.42

SUPARTZ FX provides a naturally-derived lubricant to the joint that relieves knee pain.41
