Conditions
Summary
We have clinically investigated GlycOmega Plus in two previous clinical trials (with no placebo arm) in participants with knee OA. Both trials demonstrated significant improvement in knee pain, stiffness and physical function at a dose of 3000mg per day for 8-12 weeks. This current trial aims to determine the clinical effectiveness of GlycOmega Plus in treating OA knee pain, stiffness and physical function at a dose of 1500mg for 12 weeks in a randomised placebo controlled design. Further we aim to assess faecal bacterial profiles to determine if participants with OA demonstrate altered bacterial growth and whether influencing bacterial growth with the supplementaion of GlycOmega Plus can be correlated to improve knee OA symptoms.
