Summary
Soy isoflavones (Genistein and Daidzein) are compounds found in a wide variety of foods, but mostly soy, that affect a wide-variety of body systems. They seem to mimic the female hormone estrogen to a degree (although slightly different).
They have been implicated in both reductions and increases of breast cancer risk, and generally are good at cardioprotection from reducing lipoprotein levels and are seen as good for bone health in the aging as well.

Dosage information
Many anti-carcinogenic effects of genistein are seen in the range of 10-20mg/kg bodyweight a day. Epidemiologically, this dose is also associated with reduced lipoprotein levels.
In vitro studies on glucose and muscle cell metabolism showing a nutrient partitioning effect at 20-30uM correlate to a dietary intake of 200-300mg/kg bodyweight (assuming the 1uM circulating serum levels per 10mg/kg BW intake noted.[1])
