Abstract

We conducted a meta-analysis on the available randomized clinical trials (RCTs) to assess the role of resveratrol in lowering C-reactive protein (CRP) and high-sensitivity CRP (hs-CRP) levels, as markers of inflammation, in various inflammatory disorders. Literature search through Medline/PubMed, Scopus, ISI Web of Science, and Cochrane Library yielded 35 RCTs (24 studies for hs-CRP and 11 studies for CRP). Pooled results revealed that resveratrol supplementation significantly reduced the hs-CRP (MWD = -0.40 mg/L; 95% CI: -0.70 to -0.09 mg/L; p = .01) and CRP (MWD = -0.31 mg/L; 95% CI: -0.47 to -0.15 mg/L; p < .001) levels in serum. Subgroup analysis revealed that resveratrol in group with ≥10 weeks significantly reduces hs-CRP levels (MWD = -0.48 mg/L; 95% CI: -0.92 to -0.04 mg/L; p = .03) and CRP (WMD = -0.47 mg/L, 95% CI = -0.69 to -0.25, p < .001). A dose of ≥500 mg/day supplementation improves the levels of CRP, but not hs-CRP. This meta-analysis demonstrates that resveratrol consumption is effective in lowering the levels of CRP and hs-CRP in inflammatory conditions, especially if supplementation takes place for ≥10 weeks with ≥500 mg/day.

Key Findings

This meta-analysis demonstrates that resveratrol consumption is effective in lowering the levels of CRP and hs-CRP in inflammatory conditions, especially if supplementation takes place for ≥10 weeks with ≥500 mg/day.
