EstroFlavone™ capsules, provided by Douglas
Laboratories®, contain hesperidin methyl chalcone, concentrated soy isoflavones,
and black cohosh root and rhizome extract, standardized to contain a minimum of
2.5% triterpenes. Hesperidin Methyl Chalcone: Hesperidin
methyl chalcone is a methylated derivative of the flavonoid hesperidin.
Hesperidin methylchalcone supports and protects the integrity of the
vascular system with particular activity in the capillaries and veins.
Hesperidin methylchalcone has been shown to help strengthen capillaries by
increasing capillary resistance and decreasing capillary permeability. Increased
venous motility, tone, and the ability of vessels to dilate are also enhanced by
hesperidin methylchalcone. Soy Isoflavone Concentrate: Isoflavones are
a class of phytoestrogens — plant-derived compounds that are similar in
structure and/or function to animal estrogens. In plants, isoflavones are bound
to glycosides. During digestion, colonic bacteria are thought to metabolize the
inactive isoflavone glycosides into their active counterparts. Soybeans and soy
products are the most well-known and significant dietary sources of isoflavones.
Genistein and daidzein, two of the predominant isoflavones that are beneficial
to health, are present in significant concentrations in soy foods.
Epidemiological studies have found that individuals with high soy intakes often
enjoy certain health advantages. Numerous laboratory and clinical studies have
investigated the health benefits of soy, many of which have identified soy
isoflavones as key components responsible for the health benefits associated
with soy foods. Isoflavones have both weak estrogenic and antiestrogenic
activity, which may contribute to their ability to moderate menopausal
symptoms and support maintenance of bone mineral density. Isoflavones also help
protect the cardiovascular system, support the immune system, inhibit
angiogenesis, and protect against oxidative damage as antioxidants. Black Cohosh: Black cohosh extract is
quickly gaining popularity as a natural way to moderate and balance hormone
levels. The active constituents of black cohosh appear to regulate estrogen
levels, thereby normalizing hormonal balance and moderating the symptoms that
accompany fluctuating hormone levels. Black cohosh extract works largely through
the synergistic activity of two types of compounds: phytoestrogens and
triterpenes. Phytoestrogens, a class of flavonoids with mild estrogenic activity
in the body, appear to have normalizing effects on hormonal levels. In
particular, black cohosh extract contains formononetin, an isoflavone
phytoestrogen. Triterpene glycosides found in black cohosh extract act
synergistically with formononetin to suppress excessive secretion of luteinizing
hormone (LH). Sudden increases in LH secretion, which occur in response to
declining estrogen levels, appear largely responsible for many symptoms
associated with menopause, such as hot flashes, night sweats, insomnia,
irritability, heart palpitations, and headaches. Additionally, the concerted
activity of formononetin and triterpenes appears to aid in the regulation of
estrogen balance. As with other estrogenic compounds, the active constituents in
black cohosh extract may have beneficial effects in the cardiovascular and
skeletal systems of postmenopausal women. As such, black cohosh offers a safe
and natural method of balancing fluctuating hormone levels and easing the
resulting symptoms that can occur during menopause. EstroFlavone™ may be a beneficial component of the
nutritional support program of women who wish to assist hormone balance and
support the health of blood vessels and capillaries during menopause. 1 to 2 capsules daily with meals or as directed by
physician. It is recommended that prolonged use of black cohosh beyond six
months be under physician supervision. No adverse effects have been reported. Store in a cool, dry place, away from direct
light. Keep out of reach of children. Adlercreutz H, Mousavi Y, Clark J, et al. Dietary
