INNOVATION: Discover our 2nd Generation Viscosupplements combining highly concentrated Hyaluronic Acid and Mannitol to treat Osteoarthritis

Unlike other products on the market made of hyaluronic acid only, LABRHA has developed new and innovative viscosupplements which combine highly concentrated hyaluronic acid and mannitol. Mannitol is an anti-oxidant which protects hyaluronic acid chains from free radicals and limits their degradation, increasing then their residence time in the joint cavity. Moreover, due to its free radical scavenging properties, mannitol also ensures local analgesic effect. Using LABRHA’s viscosupplements  ensures the patient rapid effect on pain and longer effect/relief over the time.

Because it is a thermal stabilizer, mannitol allows our products to guarantee a stability of their rheological properties all along their storage.
