Secondary outcomes were 3) health-related quality of life, by the ShortForm36 (SF-36); 4) inflammation grade by C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR); and 5) body composition by dual-energy X-ray absorptiometry (DXA) measured at baseline and 30 days after treatment. Data showed significant effects of supplement intake for WOMAC (β=− 3.27, p< 0.0001), Lysholm (β=1.06, p=0.0003), CRP (β=− 0.13, p=0.006), ESR (β=− 3.09, p=0.004), physical activity (β=4.3, p=0.009) and fat-free mass (β=376.7, p=0.046). A significant VAS’s decrease over time was observed in both knees (left: β=− 0.08, p< 0.0001; right: β=− 0.07, p< 0.0001).Conclusion: The tested formulation seems to be effective and also free of side effects.Keywords: pain, knee osteoarthritis, dietary supplements, Phytosome®
