Isoflavone is a soy phytoestrogen and a biologically active component of several agriculturally important legumes such as soy, peanut, green peas, chick peas and alfalfa . Soybean is an exceptionally rich source of dietary isoflavones, where the average isoflavone content is 1-2 mg/gram . The main soy isoflavones are mostly present in glycosylated forms and include Genistein, Daidzein, and glycitein, which accounts for approximately 50%, 40%, and 10%, respectively, of the total soybean isoflavone content . The clinical benefits of soy proteins have been studied and demonstrated for many years, with some evidence of soy products associated with a reduced incidences of coronary heart disease, atherosclerosis, type II diabetes mellitus, and breast and prostate cancer . While existing data are consistent or inadequate in supporting most of the suggested health benefits of consuming soy proteins and isoflavones , the trials investigating isoflavone as a potential treatment for atrophy, menopause, and postmenopausal symptoms are ongoing. Isoflavone is found as one of constituents in oral over-the-counter dietary supplements indicated for improved bone mass density and body fat regulation.
Isolated soy protein with isoflavones was shown to decrease LDL cholesterol levels in randomized trials assessed by the American Heart Association . In a study of postmenopausal women, daily dietary intake of 101 mg of aglycone isoflavones (indicating Genistein and Daidzein) was associated with lowered LDL cholesterol and apolipoprotein B levels by 8% and reduced systolic and diastolic blood pressure by 6.8% in hypertensive women . In a meta-analysis of randomized controlled trials of menopausal women, soy isoflavones attenuated bone loss of the spine and decreased the levels of deoxypyridinoline, a bone resorption marker, while increasing serum bone-specific alkaline phosphatase, a bone formation marker . The findings from studies investigating the effects of soy consumption on menopausal symptoms, breast cancer, and prostate cancer remain somewhat controversial and inconclusive. Consumption of soy isoflavones may decrease the markers of cancer development and progression in prostate cells, including prostate-specific antigen (PSA), testosterone, and androgen receptor in patients with prostate cancer but not in normal subjects . Although epidemiologic data in Asian women demonstrate that high soy food intake is associated with protection against breast cancer, soy foods have little effect on intermediary markers of breast cancer risk and postmenopausal soy intake may not reduce the risk of developing breast cancer . However, preliminary studies show that soy food intake reduces tumor recurrence in breast cancer patients . Soy isoflavones reported to interfere with thyroid peroxidase, which are involved in the production of thyroid hormones .

How Breakfix works
Isoflavones are selective estrogen receptor modulators that exert estrogenic-like effects under certain experimental conditions , as they are structurally similar to mammalian 17β-estradiol. They may bind to both α and β isoforms of estrogen receptor (ER), but with binding affinities to ERβ approximately 20 times higher than that to ERα . The role of isoflavones on estrogen-dependent cancer has been studied, since they may mediate antiestrogenic actions by blocking the binding of endogenous estrogens and their receptor signalling . In cell culture, Genistein inhibited the proliferation of MDA-MB-231 human breast cancer cells, probably by arresting the cell cycle progression at the G2–M transition . In addition, genistein was shown to induce apoptosis, modify eicosanoid metabolism, and inhibit angiogenesis . There is an evidence that soy isoflavones may act on androgen receptors to inhibit tyrosine kinase activity, thereby blocking the growth and proliferation of cancer cells .
Isoflavones may not significantly contribute to the hypolipidemic effects of soy protein, but may exert coronary benefits by improving endothelial function; in clinical trials of postmenopausal women, isoflavones improved flow-mediated dilation in women with impaired endothelial function . Some observational data suggests that isoflavones improve endothelial function by increasing the number of circulating endothelial progenitor cells, which replace damaged endothelial cells . Isoflavone may modulate the key transcription factors involved in the regulation of lipid metabolism by acting on the peroxisome proliferator-activated receptors (PPAR) alpha and gamma, which are receptors that regulate the transcription of genes involved in lipid and glucose homeostasis and lipid metabolism . Multiple biological actions of isoflavones, such as favorable effect on the blood lipid profile and inhibition of LDL cholesterol oxidation, may lead to cardio protective effects .
Genistein has been shown to have antioxidant properties on hydrogen peroxide production in vitro and blocks the formation of oxygen free radicals . Studies also suggest that at micromolar concentrations, genistein increases glucose-stimulated insulin secretion in cell lines and mouse pancreatic islets via a cAMP-dependent protein kinase mechanism . Based on the findings of experimental studies, genistein may exert a positive effect on bone formation by decreasing osteoclastic resorption factor, such as collagen C-telopeptide, and increasing osteoblastic formation markers, such as bone-alkaline phosphatase . In vitro, it antagonized the catabolic effects of parathyroid hormone (PTH) in osteoblasts by reversing the PTH-induced increase in soluble receptor activator of nuclear factor-xB ligand and decrease in osteoprotegerin expression .
Toxicity
No toxicokinetic data available.
Volume of Distribution
Isoflavones are readily distributed to all tissues, and they are known to cross the placental barrier and blood brain barrier . They are also distributed to the extra-vascular compartments. In a human study, the volume of distribution of daidzein and genistein were 336.25 L and 258.76 L, respectively .
Elimination Route
Following oral ingestion, serum isoflavone concentrations increase in a dose-dependent manner . Isoflavones are metabolized by gut microflora, where they need to undergo deglycosylation in order to be absorbed in the intestine . After oral ingestion, glycosylated isoflavones are rapidly deglycosylated, absorbed and metabolized in intestinal enterocytes and liver, entering the systemic circulation predominantly as conjugates with limited bioavailability . In humans, the mean time to reach peak plasma concentrations (Tmax) for conjugated and unconjugated genistein and daidzein are approximately 5-6 and 6-8 hours, respectively .
Half Life
The half-life of isoflavones is between 4 and 8 h . Daidzein has a longer intestinal half-life than genistein due to more rapid degradation of genistein . Individual half-life of daidzein and genistein in a human pharmacokinetic study were 7.75 h and 7.77 h, respectively .
Clearance
In a human study, the clearance rate for daidzein and genistein were 30.09 L/h and 21.85 L/h, respectively .
Elimination Route
Renal excretion is the predominant route of elimination for dietary isoflavones, where approximately 10-60% of total administered dose is excreted in urine . Glucuronide conjugates account for the majority (70-90%) of the isoflavone content in urine, followed by sulphate conjugates (10-25%) and aglycone forms (1-10%) . Fecal excretion is minimal, which accounts for 1-4% of the dietary isoflavone ingested .
