How concentrated is 1 bottle of Haelan? One bottle contains 25 pounds of non GMO and organic soy. A particular strain of bean is used and soil conditions are closely monitored in order to produce much greater concentration  of isoflavones and genistein.
Isoflavones act as phyto-estrogens or plant estrogens  by having weak estrogenic effects on the body, thereby protecting it from the more aggressive, cancer causing estrogens.
A 2013 study that searched over 4100 articles  and research trials concluded that “…isoflavones may have a protective effect on Breast Cancer and recurrence.”
The most powerful benefit of genistein is that it inhibits Breast Cancer Stem Cells. Breast Cancer Stem Cells (BCSC) were discovered in 2003 by scientists at the U-M Comprehensive Cancer Center.  U-M scientists found that only a few BCSC are responsible for the growth of a tumor. Conventional treatments of the Big 3, chemo, radiation and surgery, simply affect the tumor, but not the underlying cause.
