Numerous studies have shown that genistein and soy isoflavones have a large number of health benefits. So what are the health benefits of soy isoflavones? A relationship has been shown to exist between soy consumption and healthy cell function and proliferation, with those consuming the most soy maintaining healthier cell biological function and proliferation.
Soybeans contain three major isoflavones - genistein, daidzein and glycitein. Soy-isoflavones demonstrate tissue-selective activity, mimicking the effects of oestrogen in some tissues and blocking them in others. They are structurally similar to 17 oestradiol, a human sex-hormone, and for this reason are known as phytoestrogens or plant derived xenoestrogens, i.e. oestrogens not generated within the endocrine system but consumed via phytoestrogenic plants. They also have non-hormonal effects, including signal transduction and antioxidant activity. The health benefits of soy isoflavones may include helping to prevent bone resorption, whereby calcium is transferred from bone fluid to the blood, resulting in a loss of bone density, and stimulate bone formation without the side effects of hormone replacement therapy.
Other constituents of soy apart from isoflavones have demonstrated effects such as improved lipid metabolism or cholesterol lowering effects and antioxidant activity that may help explain the health and longer lifespan of Asian populations who consume large amounts of soy in their diet.
Since there is increasing evidence that constituents of soy other than those with 0estrogen-related activity may have significant cell-protective effects, Life Extension has developed a formula that includes soy extract standardised to isoflavones plus Natto (a traditional Japanese food made from fermented soybeans ), which may deliver further health benefits and promote longevity. Natto augments isoflavone absorption and delivers other nutrients produced during the fermentation process. Enhanced genistein, daidzein and glycitein absorption may make it necessary for only one capsule of Super Asorbable Soy Isoflavones to be taken each day. The non-genetically modified (GMO) Soynatto® in this formula is produced by a yeast fermentation process. Japanese researchers have found that this type of cultured broth from yeast can contribute to heathy cell function and proliferation.
Persons suffering from oestrogen dependent cancers should consult their doctor before embarking on supplementation with soy isoflavones.
