The Clinical Study on Isoflavone Genistein in Restructuring the Gut Microbiota of Hyperlipidemia Patients

Not Applicable

Completed

• Conditions: Hyperlipidemia

• Registration Number: NCT06895954
• Lead Sponsor: Shenzhen Hospital of Southern Medical University

Brief Summary

: In preliminary animal experiments, we found that the soybean isoflavone compound Genistein could reduce serum TMAO levels in high-fat diet (HFD) mice, and this effect was dependent on the gut microbiota. Furthermore, we discovered that Genistein's regulatory effect on the gut microbiota in high-fat diet mice relies on the host colonic PKI-Nos2 pathway. Genistein is an isoflavone compound extracted from soybeans and is the most effective functional ingredient in soybean isoflavone products. It has multiple physiological functions, and several randomized controlled trials (RCTs) have shown that the intake of Genistein can effectively alleviate hyperlipidemia, obesity, metabolic syndrome, and cardiovascular diseases, suggesting its safety and efficacy as a clinical health supplement. Therefore, we aim to conduct clinical trials to further demonstrate that Genistein also influences the gut microbiota in hyperlipidemia patients, thereby reducing serum TMAO levels.
