Probiotic complex, zinc, and coenzyme Q10 (CoQ10) are recognized dietary supplements with an anti-inflammatory role. Although these supplementations are individually known to benefit rheumatoid arthritis (RA), there is no evidence suggesting any synergic effect. The primary goal of this study is to determine whether probiotic complex, zinc, and CoQ10 attenuate the development of collagen-induced arthritis (CIA). The combination of probiotic complex, zinc, and CoQ10 reduced CIA severity by downregulating the levels of IgG, IgG1, and IgG2a in serum. Joint inflammation, bone destruction, and cartilage damage were also improved by the complex. There was a decrease in the expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-17, and vascular endothelial growth factor (VEGF) in the joint synovium. The balance between helper T 17 (Th17) cells and regulatory T (Treg) cells was shown to be controlled reciprocally by the complex. These findings suggest that the combination of probiotic complex, zinc, and CoQ10 can ameliorate the development of CIA by inhibiting the expression of proinflammatory cytokines, and is thus an important therapeutic candidate for RA treatment.
