Soy May Help Older Women Sleep Better

The estrogen-like compounds found in soy could help postmenopausal women get a better night’s sleep, according to a small study.

To investigate whether isoflavones might be beneficial, Researchers randomly assigned 38 postmenopausal women with insomnia to take either 80 milligrams of the isoflavones or a placebo for four months.

In the isoflavone group, average sleep efficiency (meaning the percentage of time that the women spent in bed that they were actually sleeping) went from 78 percent at the beginning of the study to 84 percent at the end; for the placebo group, sleep efficiency increased from 78 percent to 81 percent.

Among women given isoflavones, 90 percent reported “moderate or intense” insomnia at the beginning of the study, while 37 percent did after four months; in the placebo group, the percentages were 95 percent and 63 percent, respectively.
