I have recently become aware of a joint supplement product called Trigosamine, which is now being marketed in the United States at most popular drug stores.
The Trigosamine supplement is said to combine Hyaluronate with the essential blend of Glucosamine and Chondroitin.
Hyaluronate is the natural substance found in synovial joints, which functions to lubricate the joints allowing them to move with little or no friction.
Glucosamine and Chondroitin are thought to help build and maintain healthy articular cartilage in joints allowing for increased flexibility, range of motion and comfort.
The difference between this and other joint supplements, also known as neutraceuticals, is that it claims to contain Hyaluronate.
The catch is how Hyaluronate can go from an oral form through the intestine, then the liver, etc. and get into the joints in the same natural form needed to lubricate the joints. This is very unclear to me.
I am not endorsing Trigosamine, but only mentioning it because you will see it advertised. I intend to research this much more and report back with additional information on it.
