Soy isoflavones are a type of polyphenolic compound formed during the growth of soybeans as a secondary metabolite. The main natural types of soy isoflavones include genistein, daidzein, daidzein, coumarin A, and anthocyanin. Soybeans and soy products are the main food sources of soy isoflavones. Soy isoflavones can bind to estrogen receptors, exert estrogenic and endogenous estrogenic effects, hence they are called phytoestrogens.

Yellow to light yellow powder, with a bitter taste. Soluble in water, heat-resistant (remains unchanged when heated at 120 ℃ for 30 minutes, residual 80% when heated at 180 ℃ for 30 minutes), acid resistant (pH=2.0 remains stable).

Soybean isoflavones, as food, health products, and pharmaceutical raw materials, can be made into various anti-cancer drugs, health products, and so on. Mainly used to prevent menopausal syndrome, osteoporosis, etc. in middle-aged and elderly people, it is beneficial to provide a quality of sexual life.

The main functions of isoflavones:

1. It can reduce LDL cholesterol, help prevent or treat menopausal regulation, and provide the body with the necessary linoleic acid and linolenic acid.

2. Improve the balance of cholesterol in the blood and reduce the concentration of cholesterol in the blood.

3. Make the arteries more elastic to prevent damage to the heart.

4. Enhance bone density, reduce calcium loss, and reduce the chance of osteoporosis.

5. Reduce the chance of developing cancer, especially breast and prostate cancer.

6. Relieve menopausal discomfort, such as redness, fever, emotional instability, headache, insomnia, fatigue, night sweats, and vaginal dryness.

7. Treating Qi and other syndromes, redness, osteoporosis, cardiovascular disease, and cancer can help combat coronary heart disease.

Flavonoids can reduce the formation of free radicals and aid in the regeneration of other antioxidants. Soy isoflavones are natural plant estrogens that are beneficial to the human body. Plant bioactive substances extracted from natural soybeans have a very similar molecular structure to estrogen and can bind to estrogen receptors in the female body. They have a bidirectional regulatory effect on estrogen, are safe and have no side effects, so they are also known as "plant estrogens". It can alleviate various symptoms such as osteoporosis caused by menopause, delay skin aging, improve skin quality, and make women's skin smooth, delicate, and elastic. It is known as the "female charm factor" because it can greatly improve the quality of life for women.
