Safe, natural pain relief and more: Choosing hyaluronic acid may help you delay the need for knee replacement surgery.22

HA is the abbreviation for hyaluronic acid. Clinical studies from around the world have shown that hyaluronic acid can provide osteoarthritis pain relief, reduce the requirement for pain relief and anti-inflammatory medications,4 and that treatment with hyaluronic acid can provide longer-lasting pain relief than steroid injections.2

But hyaluronic acid does more than just relieve pain: It enhances the lubrication and shock-absorbing qualities of the fluid that naturally surrounds your joint. This helps protect your joint from daily wear-and-tear damage that can lead to surgery sooner rather than later.21

What Is Hyaluronic Acid?

Hyaluronic acid, also referred to as hyaluronan or hyaluronate, is a molecule found naturally throughout the human body. You might recognize hyaluronic acid as an ingredient in some skin care products. Hyaluronic acid performs many functions in the body, two of which include hydration of the skin and lubrication of joints.23 Hyaluronic acid is an important component of synovial fluid, a thick substance that lubricates healthy joints.

Synovial fluid enables joints to move easily and freely, while also absorbing the shock that occurs in joints during physical activity. In a healthy joint, this fluid protects bones and other joint tissues from injury and disease. This is referred to as the viscoelastic properties of synovial fluid.
