Arm Intervention/treatment
Experimental: Flexofytol (bio-optimized curcumin) Dietary Supplement: Flexofytol (bio-optimized curcumin)
2x3 caps/day (before breakfast and in the evening) for 3 months

Primary Outcome Measures :
  1. Serum levels of biomarkers of cartilage metabolism and inflammation [ Time Frame: 84 days ]
    Change from baseline of serum levels of biomarkers

Secondary Outcome Measures :
  1. Pain and the global patient assessment of disease activity using a Visual Analog Scale (VAS) [ Time Frame: 84 days ]
    Change from baseline of the mean pain over the last 24 hours and of the global assessment of disease activity by the patient
