Isoflavones obtained from red clover improve both dyslipidemia and menopausal symptoms in menopausal women: a prospective randomized placebo-controlled trial

Objective: This study aimed to investigate the effects of red clover isoflavones on menopausal symptoms and the lipid profile in menopausal females. Methods: This study included postmenopausal women with dyslipidemia. The red clover group (n = 39) received 40 mg isoflavone red clover capsule twice daily for 6 months, while placebo (n = 36) was 40 mg starch capsule twice daily. Data were collected at baseline, 3 months and 6 months. The Menopause Rating Scale (MRS) was applied to calculate subdimension and total scores. Results: The two groups were similar in terms of age, MRS and lipid profile at baseline. In the red clover group, MRS scores decreased significantly at both 3 and 6 months. Similarly, total cholesterol, low-density lipoprotein cholesterol (LDL-C) and triglyceride levels decreased at both 3 months and 6 months. High-density lipoprotein cholesterol increased significantly from baseline to 3 months and 6 months. Except for LDL-C and MRS urogenital score at 3 months, the improvements were significantly in favor of red clover isoflavone treatment. Conclusions: Red clover treatment for 3–6 months demonstrated significant improvements in lipid profiles and menopausal symptoms. While promising, further research is crucial to ascertain long-term safety and recommend the use of red clover isoflavones during menopause.
