Genistein Soy Isoflavones 1,000 mg Tablets and Powder
Isoflavones are a type of phytoestrogen found in high amounts in soy foods.
Genistein is one of the most metabolically active isoflavones. Soy isoflavones,
including genistein, have a weak estrogenic effect in the body that can be either
agonistic or antagonistic. In other words, phytoestrogens can either mimic or
block the effect of estrogen. Soy isoflavones can reduce the incidence
of hot menopausal hot flashes, and can also help maintain a healthy prostate
gland in men.
Soybean is one of the plants containing the isoflavone genistein, which can
help regulate and maintain normal menstrual cycles and menopausal transitions.
In addition, it provides a wide variety of the many health benefits associated
with soy.
Genistein and Estrogen
The subject of scientific studies since 1966, genistein research has been published
in many respected journals. In vitro, genistein has been shown to bind to the
same receptor sites as estrogen. This may help to maintain normal menstrual
cycles and menopausal transitions by two competing and seemingly paradoxical
actions. By competing for human estrogen receptors, genistein may reduce the
effects of estrogen in the body. Conversely, when there is too little estrogen
(the situation during menopause), phytoestrogens - genistein and daidzein -
may substitute for the lack of human estrogen, mitigating the effects of its
absence.
Genistein and Cell Growth
One of genistein's most promising functions is its potential to inhibit capillary
proliferation. According to studies done in vitro, genistein protects tissues
by neutralizing vascular endothelial growth factor (vegF). Soybeans are the
only significant dietary source of genistein; however, most Americans fail to
consume soy foods in significant amounts. In Asia, the daily intake can be up
to 20 times that of a Western diet.
