Results show quercetin supplementation for 8 weeks significantly reduced early morning stiffness, morning pain, and after-activity pain (p < 0.05).

Disease Activity Score 28 and assessment questionnaire scores decreased in the quercetin group compared to placebo and the number of patients with active disease significantly decreased in the quercetin group.

Plasma hs-TNFα level was significantly reduced in the quercetin group compared to placebo (p < 0.05).

There were no significant differences in tender and swollen joint counts between groups but tender joint counts significantly decreased in the quercetin group after the intervention. Supplementation had an effect on erythrocyte sedimentation rate but it was not significant (p > 0.05).
