Comparative Efficacy of Nutraceuticals on Endothelial Function: A Systematic Review and Network Meta-Analysis
Abstract
Purpose of review: This network meta-analysis (NMA) compares the efficacy of dietary interventions in improving flow mediated dilation (FMD) as a measure of endothelial function among individuals with cardiovascular diseases (CVDs) and hypertension. This work can be a basis for the design of future clinical trials and for the development of evidence-based nutritional guidelines to improve cardiovascular outcomes.
Recent findings: The most substantial improvements in FMD were observed with magnesium (MD: 8.17; CoE: High), vitamin D3 (MD: 7.84; CoE: High), flaxseed (MD: 7.39; CoE: Low), barberry (MD: 6.64; CoE: Moderate), folic acid (MD: 3.36; CoE: Low), and omega-3 (MD: 1.83; CoE: Very low). Sensitivity analyses confirmed the robustness of these findings. Several dietary interventions, particularly magnesium and vitamin D₃, have been shown to improve endothelial function in individuals with CVDs and hypertension. These findings highlight the potential role of nutritional strategies as adjunct therapies for preserving vascular health.
Trial registration: Systematic review registered with PROSPERO, registration number CRD420251041093.
