Postmenopausal women experience an increase in cardiovascular, sexual, and emotional changes that can significantly impact their quality of life. Although phytoestrogens offer therapeutic benefits, our understanding of resveratrol's effects remains limited. This study aims to evaluate the effects of using resveratrol on the lipid profile of postmenopausal women. We conducted a systematic review using search terms like "postmenopausal" and "resveratrol" and their synonyms. Two reviewers handled study selection and data extraction. Randomized clinical trials assessing resveratrol in post-menopausal women were included. The meta-analysis on total cholesterol levels found no significant difference between groups, Standardized Mean Difference (SMD) -0.09 (95% Confidence Interval (CI) -0.39 to 0.22, p=0.59; I2=0%, 2 studies, low-quality evidence). No significant differences were found in high-density lipoprotein (HDL) levels, SMD 0.00 (95% CI -0.31 to 0.31, p=1; I2=0%, 2 studies, low-quality evidence), Low-Density Lipoprotein (LCD) levels, SMD -0.10 (95% CI -0.40 to 0.21, p=0.54; I2=0%, 2 studies, low-quality evidence), and triglyceride levels, SMD -0.12 (95% CI -0.18 to 0.43, p=0.43; I2=0%, 2 studies, low-quality evidence). This review concludes there's limited evidence for recommendations; further studies with higher doses, longer supplementation durations, and exploration of outcomes are needed to clarify therapeutic potential.
