with chronic inflammation and b) to evaluate the effectiveness of NKO™ on arthritic symptoms.
Randomized, double blind, placebo controlled study. Ninety patients were recruited with con-
firmed diagnosis of cardiovascular disease and/or rheumatoid arthritis and/or osteoarthritis and with increased
levels of CRP (Ͼ1.0 mg/dl) upon three consecutive weekly blood analysis. Group A received NKO™ (300 mgdaily) and Group B received a placebo. CRP and Western Ontario and McMaster Universities (WOMAC)
