Brief Introduction:

Soy isoflavones are a class of secondary metabolites formed during the growth of soybeans. They are a type of bioflavonoids and also a type of phytoestrogen.

Soy isoflavones are a mixture with a polyphenol structure, there are three main groups, namely Daidzein Groups, Genistin Groups, and Glycitin Groups. Each group exists in four forms: ① Free Form, ② Glucoside Form, ③ Acetyl Glucoside Form, ④ Malonyl Glucoside Form.

The estrogenic effect of soy isoflavones affects hormone secretion, metabolic biological activity, protein synthesis, and growth factor activity. It is a natural chemopreventive agent for cancer.

Physiological Functions and Effects:

Soy isoflavones are a type of plant estrogen with multiple physiological functions, they can be used to prevent and treat menopausal syndrome, cardiovascular diseases, cognitive impairment and certain cancers.
1) Phytoestrogen Effect:
The structure is similar to human estrogen (β-Estradiol), which can regulate hormone levels in both directions:
▼ When estrogen levels are low (such as menopause): weak supplementation to relieve hot flashes and osteoporosis.
▲ When estrogen levels are high (such as women of childbearing age): compete for receptors to reduce the risk of estrogen overstimulation.

2) Antioxidant Effect:

Remove free radicals, reduce oxidative damage, and delay cell aging.

3) Cardiovascular Protection:

Reduce low-density lipoprotein (LDL), improve vascular elasticity, and may reduce the risk of arteriosclerosis.

4) Anti-cancer Potential:

Studies have shown that soy isoflavones may reduce the risk of breast cancer and prostate cancer (the mechanism includes inhibiting tumor angiogenesis).

5) Bone Health:

Reduce bone loss, especially for menopausal women to prevent osteoporosis.

Application Areas:

1) Health Food:

Soy isoflavones can be added to health food to relieve menopausal symptoms, anti-oxidation or maintain bone health.

2) Medicine:

Soy isoflavones can be used to study its role in cancer adjuvant treatment and cardiovascular disease prevention.

3) Cosmetics:

Soy isoflavones can be added to anti-aging products using its antioxidant properties.
