Geliton® is a registered trademark of the Finnish medical device company Medin. Geliton® products are made of sodium hyaluronate, a natural component of the human body that is found in the skin, cartilage, and synovial fluid. Sodium hyaluronate is a complex sugar molecule that has the ability to absorb and hold large amounts of water, which makes it an effective lubricant and shock absorber. In Geliton® products, sodium hyaluronate is cross-linked to form a gel that is injected into the knee joint to relieve pain and improve mobility.
