Joint Fuel is a scientifically advanced nutraceutical which contains cartilage and tendon supporting nutrition. This easily digested capsule helps support healthy cartilage, tendon and joint function. By providing joints with the essential raw materials, glucosamine sulfate can help support healthy cartilage. Research shows that it is absorbed into the body at a rate much more effective than other "joint-supporters". Because of the small size of the molecules, they are absorbed at a rate of 98%--compare that to the mere 13% absorption rate of chondroitin sulfate, and you can understand why glucosamine sulfate works so much better. By stimulating production of additional synovial fluid, studies show that glucosamine sulfate helps keep joints in the body rolling smoothly. Recent studies have found that as a readily absorbed building block for cartilage, glucosamine sulfate works to support healthy cartilage in humans.
