The present invention relates to a use of D-chiro-inositol, pinitol, or analog compounds thereof for preventing or treating female menopausal symptoms. The active ingredient compound of the present invention has an effect of increasing the activity of female hormones by increasing the blood concentration of 17&#x3b2;-estradiol and lowering the blood concentration of sex hormone-binding globulin. Therefore, the active ingredient compound of the present invention can be developed as a drug or a nutraceutical for preventing, alleviating or treating female menopausal symptoms. The active ingredient of the present invention is derived from a natural product, and thus, unlike an agonist of female sex hormones or chemically synthesized sex hormones, has very few side effects when applied to the human body.
