A combination supplement that includes glucosamine might curb knee pain, according to a study from Tokai University in Japan. A daily supplement that included a variety of compounds, including 1,200 milligrams glucosamine, 60 milligrams chondroitin sulfate, 90 milligrams quercetin glycosides, and 5 micrograms vitamin D, was given to 30 people suffering from knee pain. Gait analysis was done at the start and finish of the study along with gait parameters, such as normal walking speed, stride length, cadence, and angle of soles. At the end of 16 weeks, results showed the supplemented group scored higher on all tests for gait, except cadence. The researchers conclude that this supplement program improved walking ability, which suggests an alleviation of knee pain.
