Purpose: To compare and evaluate the effects of treatment with a blend of glucosamine and chondroitin sulfate, or a blend of glucosamine, chondroitin sulfate and calcium fructoborate as compared to a placebo, on joint discomfort. Methods: Individuals with self-reported knee discomfort were randomized and blinded to treatment with a combo containing glucosamine and chondroitin sulfate or glucosamine, chondroitin sulfate and calcium fructoborate. Both groups were compared to placebo. Symptoms of discomfort and joint function were assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and the McGill Pain Questionnaire (MPQ) before treatment and after 7 and 14 days of treatment. Results: Ninety individuals were selected for this study and were randomly assigned in groups of 30 containing 15 male and 15 female participants to each of three treatment conditions. Treatment with glucosamine combined with chondroitin sulfate and CFB resulted in a statistically significant 24% reduction of mean WOMAC score and a 25% reduction of mean McGill index at day 14 over baseline (p-value = 0.0006 and p-value < 0.0001, respectively). Treatment with placebo or with glucosamine and chondroitin material did not result in significant improvement of the conditions. Conclusions: Results showed that short-term treatment with glucosamine and chondroitin could be efficacious only if used in combination with CFB.
