Effects and Functions of Soy Isoflavones
Soy isoflavones are bioactive compounds refined from non-genetically modified soybeans. They are natural nutritional factors possessing multiple important physiological activities and represent purely plant-derived estrogens.

1. Improvement of postmenopausal osteoporosis: Soy isoflavones—or their metabolites—exert weak estrogenic effects in postmenopausal women. By binding to estrogen receptors on osteoblasts, they enhance osteoblast activity, thereby promoting the production and secretion of bone matrix and facilitating bone mineralization, ultimately improving osteoporosis.
2. Anti-aging and skin beautification: As a natural plant estrogen, soy isoflavones effectively supplement endogenous estrogen in women, resulting in smoother, softer, finer, and more elastic skin.
3. Alleviation of menopausal syndrome: The estrogen-like activity of soy isoflavones helps compensate for declining estrogen levels in women, thereby alleviating symptoms associated with menopause.

4. Improvement of cardiac arrhythmias: Soy isoflavone compounds improve myocardial ischemia through multiple mechanisms—including vasodilation, inhibition of platelet aggregation, reduction of serum cholesterol and triglyceride levels—and exert anti-arrhythmic effects.
