Soy Isoflavones Powder

 

Soy isoflavones powder (ISO) is a plant-based estrogen, also known as a natural hormone. It is a secondary metabolite formed during the growth of soybeans.

 

There are currently 12 types of soy isoflavones discovered, divided into two categories: free aglycones and bound glycosides.

 

It is a light yellow powder with a slightly bitter smell and a slightly astringent taste. The aglycone has a stronger unpleasant flavor than the glycoside.

 

The free aglycone in soybean isoflavones is generally insoluble in water, but soluble in organic solvents such as methanol, ethanol, ethyl acetate, ether, and dilute alkali.

 

The conjugated glycoside is easily soluble in methanol, ethanol, pyridine, ethyl acetate and dilute alkali, but is insoluble in organic solvents such as benzene, ether, chloroform, petroleum ether and so on. Solubility in water increases significantly with increasing temperature.

 

 

Soy isoflavones mainly exist in soybeans and their products, such as tofu, soy flour, soy milk, soy milk, soy cheese, bean paste, fermented bean curd and tempeh.

 

In addition, soy isoflavones powder are also contained in certain plants such as okra, red clover, celeriac, kudzu, clover and alfalfa. In soybeans and their products, soybean isoflavones mainly exist in the form of bound glycosides. After soybeans are fermented or germinated, the content of free aglycones increases.

1. Antioxidant effect
Soy isoflavones are also a type of strong antioxidant that can effectively remove free radicals in the body and on the skin surface, delay cell aging and protect the skin.

 

2. Estrogen
At present, most researchers believe that the estrogenic effect of soy isoflavones powder is due to its structural similarity to estradiol. However, the estrogenic effect of soy isoflavones is weak, about 1/1000 of estradiol.

 

Experiments have shown that soy isoflavones can bind to endogenous estrogen receptors, mainly to the beta subtype of estrogen receptors (ERβ), to exert estrogenic effects.

 

3. Improve menstrual symptoms
Dietary supplementation of soy isoflavones can effectively reduce the frequency of hot flashes in perimenopausal women, reduce their severity, shorten their duration, and improve perimenopausal syndrome.

 

 

4. Improve osteoporosis
Research shows that soy isoflavones powder can inhibit bone resorption, promote bone formation, improve bone density in postmenopausal women, and alleviate the occurrence of osteoporosis.

 

5. Protect cardiovascular system
Studies have shown that soy isoflavones can improve the function of vascular endothelial cells. It can significantly reduce blood lipid levels and is a protective factor for blood vessels.

 

6. Anti-aging
Soy isoflavones can make women's skin smoother, more delicate, and more elastic. Especially for some middle-aged women, taking appropriate amounts of soy isoflavones can also delay aging and have a beautifying effect.
