简要总结
We propose to perform a 24-week randomized, double-blind a placebo-controlled trial among 207 non-equol producing postmenopausal women with prehypertension to examine the effectiveness of equol (10mg and 20mg/d) on 24h ambulatory blood pressure, vascular function and other cardiovascular risks (lipid profile, glycemic control and inflammatory biomarkers) and explore the optimal dosage of equol.
