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.

People with knee osteoarthritis have diluted hyaluronic acid in the synovial fluid – reducing the fluid’s lubrication and shock-absorbing properties.15,24

Administered as a series of 3 to 5 injections directly into the knee, SUPARTZ FX works as a viscosupplement, temporarily increasing the levels of healthy hyaluronic acid in the affected joint.16 The hyaluronic acid (HA) in SUPARTZ FX safely reduces joint pain and stiffness.16,22 HA in the knee acts as a supplemental lubricant and shock-absorber. The HA in SUPARTZ FX has the same composition as the natural hyaluronic acid your body produces.15,16,22

The HA in SUPARTZ FX relieves knee pain in the joint.22
