This meta-analysis of 25 randomized controlled trials (RCTs) investigated the effects of taurine supplementation on metabolic syndrome (MetS) parameters. A total of 1024 participants were included. Taurine supplementation significantly reduced systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), and triglycerides (TG), with a dose-dependent effect observed for DBP and FBG. No significant increase in high-density lipoprotein cholesterol (HDL-C) or adverse effects were observed. Taurine shows promise as a potential dietary addition for MetS management, although further research is needed to optimize dosage and explore long-term benefits.
