INTRODUCTION: Phytosterols are recognized for their cholesterol-reducing effects and are commonly used as dietary supplements or added to foods due to their potential cardiovascular benefits. However, evidence regarding the impact of phytosterol supplementation on inflammatory markers remains inconclusive.
AIM: This systematic review and meta-analysis aim to evaluate the effect of phytosterols in reducing levels of C-reactive protein (CRP) and high-sensitivity CRP (hs-CRP).
METHODS: A systematic literature search of the primary databases was conducted up to May 2024 to identify eligible studies. The measurement of effect sizes was determined using WMD (weighted mean difference) and 95% CI.
RESULTS: For the meta-analysis, 14 publications (19 study arms) for hs-CRP and 10 publications (16 study arms) for CRP were included. The pooled analysis showed that the administration of phytosterol did not significantly reduce CRP compared to control with WMD= -0.04 mg/l (95% CI: -0.28 to 0.20, P = 0.74). However, phytosterol supplementation significantly decreased the hs-CRP level compared to the control group with WMD of -0.25 mg/l (95% CI: -0.42 to -0.07, P = 0.006). The WMD for hs-CRP reduction was - 0.36 mg/l (95% CI: -0.53 to -0.18, P < 0.001) for supplementation with a phytosterol dose ≥ 2000 mg/day compared to the control group.
CONCLUSIONS: Phytosterol supplementation may be effective in reducing hs-CRP levels.
