Method:A randomized, double-blind, placebo-controlled clinical trial was conducted over 6 months with 96 healthy menopausal women. After taking take 135 mg of isoflavones daily for 1 week, the women in the study group were assigned to the equol-producing (EP) or the non-EP group according to the presence or absence of equol in their urine. Menopausal symptoms were evaluated using a modified Kupperman Index. Result:Compared with the placebo group, the scores for hot flashes and excessive sweating were significantly reduced after 3 months, and the scores for weakness, palpitations, limb paresthesia, and total symptoms after 6 months, in the EP group only. Conclusions:Isoflavone supplementation improves menopausal symptoms only in women with the ability to produce equol.EquolHot flashesIsoflavonesMenopausal symptomsEffect of intestinal production of equol on menopausal symptoms in women treated with soy isoflavones
