Abstract
Dyslipidemia is a known risk factor for cardiovascular diseases (CVD). Research indicates that curcuminoids plus piperine co-supplementation (Curc + Pipe) can alter serum lipids. However, the findings from various studies are inconsistent. This meta-analysis aims to evaluate the efficacy of Curc + Pipe in serum lipid parameters in adults. A systematic search was conducted in databases until August 2025 to identify eligible randomized controlled trials (RCTs). To estimate the pooled effect size, weighted mean differences (WMDs) with corresponding 95% confidence intervals (CIs) were calculated, applying a random-effects model to account for potential variability between studies. A pooled analysis of 16 RCTs, encompassing a total of 1038 participants (Intervention: 522, Control: 516) revealed that Curc + Pipe significantly reduced triglycerides (TG) (WMD: -18.64 mg/mL, 95% CI: -29.94, -7.34, p < 0.001) and total cholesterol (TC) (WMD: -6.58 mg/mL, 95% CI: -12.60, -0.55, p = 0.032) and increased high-density lipoprotein cholesterol (HDL-C) (WMD: 1.51 mg/mL, 95% CI: 0.29, 2.72, p = 0.015). However, the reduction in low-density lipoprotein cholesterol (LDL-C) was not statistically significant (WMD: -2.20 mg/mL, 95% CI: -7.22, 2.80, p = 0.387). Curc + Pipe has clinically meaningful lipid-modulating effects, particularly in reducing TG and TC and modestly increasing HDL-C levels. These benefits were most pronounced in more prolonged supplementation in individuals with dyslipidemia, metabolic disorders, and overweight. Clinically, Curc + Pipe may serve as a valuable complementary therapy for dyslipidemia management to decrease the risk of CVD.
