Abstract

Introduction and Aim: Research on the effects of propolis consumption on body composition, and blood pressure (BP) has produced inconsistent results. This systematic review and dose-response meta-analysis was carried out to compile the data from the randomized controlled trials (RCTs) on how propolis supplementation affects body composition, and BP level in adults. Materials and Methods: A systematic literature search was conducted using electronic databases, including PubMed, Embase, Scopus, Web of Science, and Cochrane library, up to January 2024. The RCTs, evaluating the effects of propolis consumption on weight, body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-hip ratio (WHR), fat mass (FM), systolic BP (SBP), and diastolic BP (DBP), were included in the study. We used the random-effects model to establish the pooled effect size. Results: A total of 22 RCTs involving 1082 participants were included in the study. Propolis supplementation demonstrated significant reductions in weight (weighted mean difference [WMD]: –0.37 kg; 95% confidence interval [CI]: –0.63 to –0.12), and BMI (WMD: –0.11 kg/m2; 95% CI: –0.13 to –0.09). However, there were no significant effects on WC, WHR, FM, HC, SBP, and DBP levels. The dose-response analysis revealed a significant nonlinear relationship between propolis dosage and WC (P = 0.020). Moreover, the BMI (P = 0.047) and WC (P = 0.004) reduction trend continues until 8 weeks of intervention and then this impact plateaued. Conclusions: Supplementation with propolis seems to be effective in reducing weight and BMI. However, it should be noted that the anti-obesity properties of propolis supplementation were small and may not reach clinical importance. Therefore, future well-designed studies with a large sample size are needed to investigate the effect of propolis on body composition and BP in adults. © 2024 The Author(s)
