Synolis VA - Injectable Joint Supplement
Designed For Your Movements

Synolis VA is a Swiss-made joint injection supplement that fights the effects of osteoarthritis (OA) by mimicking the properties of synovial fluid.

It's proprietary technology includes a high molecular weight hyaluronic acid (HA) combined with a high concentration of sorbitol.

Delivered in either a 2ml and 4ml sterile syringe, Synolis VA provides optimal treatment flexibility. 

Synolis, inspired by synovial fluid

Synolis is designed to adapt to the needs of the joint during movement. 

  • Patented cross-over frequency of 0.4Hz similar to a healthy synovial fluid.

  • During movement, the rheological properties of a healthy synovial joint switches from viscous to elastic to ensure a seamless and pain free movement. Patients suffering from OA loose this viscoadaptivity.

Synolis supplements the joints by enhancing the viscoelastic properties of the synovial fluid

  • High Molecular Weight

  • Non-crosslinked

  • Non-animal origin / bio fermentation

  • Protects HA from degradation

  • Physico-chemical properties (Osmolality, pH) close to synovial fluid

  • Excellent Safety Profile

Clinical Proven Efficacy

A single injection of Synolis 80/160 can significantly reduce pain in patients with osteoarthritis of the knee¹²

Significant improvement in function and stiffness in patients with knee osteoarthritis receiving a single injection of Synolis 80/160¹²

Synolis is a safe and well tolerated treatment with less than 0.01% adverse event rates ¹²³⁴⁵
