In one study, eighty subjects diagnosed with varying degrees of osteoarthritis were given either a placebo supplement or 1.5 grams of glucosamine sulfate per day for thirty days. Tests to determine joint swelling, pain, and mobility were performed on all of the subjects each week throughout the study. Some subjects using either the placebo or glucosamine supplement also had a sample of their joint cartilage studied with an electron microscope following thirty days of supplementation. Each subject was also monitored for possible side effects during the course of the study.
