Effect of Two Different Isoflavone Supplement Preparations on Gene-expression in Postmenopausal Women — ISOII  

Postmenopause Clinical Trial

Official title:
Effect of Two Different Isoflavone Supplement Preparations on Gene-expression in Postmenopausal Women

Clinical Trial Summary

Alleged benefits experienced after the consumption of soy in Asian countries have been attributed to the isoflavone content of soy products. Amongst other benefits, isoflavones are believed to relieve menopausal symptoms and are therefore often consumed in supplement form in Western countries. These supplements contain relatively high amounts of isoflavones and are on the market in different compositions. The question is whether supplements with different compositions exert similar effects or whether the effects differ substantially.

Clinical Trial Description

Intervention study with two substudies; each substudy is a double blind placebo controlled crossover intervention study. The first substudy has two groups: 'high daidzein' supplement versus placebo (n=18) and vice versa (n=18); the second substudy also has two groups 'high genistein' versus placebo (n=18) and vice versa (n=18). ;
