The estrogen link with soy has been known for awhile. I did a quick web
search, possibly someone could calculate out how much formula would be
equivalent to a pill.

=PHYTO-WHAT? Phyto is the Latin word for plants and we are
familiar with the often-disruptive estrogen hormones.
Isoflavones - a
primary component of many plants and herbs - is widely
recognized as
a valued phytoestrogen. Today millions of women are using these
natural plant estrogens as alternatives to typically
prescribed Premarin
(mare's urine) and Provera (a synthetic "progestin").
High blood levels of estrogen can cause P.M.S., growth of
precancerous cells, endometriosis or breast cancer according to
Christianne Northrup, M.D. in Women's Bodies, Women's Wisdom.
Too little estrogen, as in menopause, can result in loss of
bone density
(osteoporosis), hot flashes, night sweats and heart disease.
Lower risks of breast cancer in Japanese women are attributed
to two
important isoflavones - genstein and daidzien. These hormonal
balancers are abundant in soy. In Dr. Whitaker's Guide to Natural
Healing, he states that a cup of soy is equivalent to "0.45
milligram of
conjugated estrogen or one tablet of Premarin." (A 12%
reduction of
LDL [bad] cholesterol and 10% reduction of serum
triglycerides were
added benefits of eating soy products.)

This was interesting, for my son who has a major reaction to the soy
protein. It explains why he's so sensitive to the soy protein isolate.
