The effects of ursolic acid on cardiometabolic risk factors: a systematic review and meta-analysis

Aim: Ursolic acid (UA) has an important biological role in the fight against fat accumulation, insulin resistance, obesity and inflammation. Therefore, in the current review and meta-analysis work, we investigate the effects of UA (dosage range is 50.94 to 450 mg/day) on cardiometabolic risk factors. Materials & methods: After searching the studies up to February 2023, six articles were included in the study. Results: The pooled effect size showed that UA supplementation didn't significantly change body weight, body mass index, waist circumference, body fat percentage, lean body mass, systolic blood pressure, diastolic blood pressure, fasting blood glucose, insulin, triglycer ide and high-density lipoprotein compared with control groups. Conclusion: UA supplementation had no significant effect on the cardiometabolic risk factors in adults. Plain language summary: Cardiovascular disease (CVD) is a significant reason for morbidity and mortality. Ursolic acid (UA) has been shown to play important biological roles in the fight against fat accumulation, oxidative stress, insulin resistance via insulin-like growth factor 1, cancer, muscle atrophy, obesity and inflammation responsible for CVD. A systematic review and meta-analysis were conducted up to February 2023; six articles were included in the study and eleven cardiometabolic risk factors were identified. The pooled effect size showed that UA supplementation (dosage range is 50.94 to 450 mg/day) didn't significantly change body weight, body mass index, waist circumference, body fat percentage, lean body mass, systolic blood pressure, diastolic blood pressure, fasting blood glucose, insulin, triglyceride, and high-density lipoprotein compared with control groups.
