CS+GH has comparable efficacy to celecoxib in reducing pain, stiffness, functional limitation and joint swelling/effusion after 6 months in patients with painful knee osteoarthritis, with a good safety profile.
Over 2 years, no treatment achieved a clinically important difference in WOMAC pain or function as compared with placebo, however, glucosamine and celecoxib showed beneficial but not significant trends.

Patients with non‐erosive reflux disease (NERD) are less responsive to proton pump inhibitors (PPIs) than those with erosive disease as they belong to different subgroups, in whom factors other than acid can trigger symptoms.
The combined administration of the supplement with hydrolyzed diet over 180 days was safe and induced improvements in selected serum biomarkers, possibly suggesting a reduction in disease activity.
Circuit style resistance-training and weight loss improved functional capacity in women with knee OA and functional aerobic capacity was increased to a greater degree for those in the HP and GCM groups while there were some trends suggesting that supplementati
