Exploratory Non Comparative Study to Evaluate the Efficacy of Highly Bioavailable Curcumin (Flexofytol) in Patients With Knee Osteoarthritis

The purpose of this study is to evaluate the efficacy of bio-optimized curcumin(Flexofytol) during a 90-days period in knee ostearthritis patients on the serum levels of specific biomarkers of osteoarthritis and on the evaluation of pain.
