Soy protein

[Ruhl]

Which has the least estrogenic effects: soy protein powder or tofu?

Doesnt matter

Still...

Soy protein (isolate) supposedly contains no isoflavones. I have only heard this and havent really ever done any research on it.
All veges contain phytoestrogens. For some reason people seem to think that soys are worse than others

With soy protein isolate you'll have the least effect from soy isoflavones.

With a whole soy powder featuring "Soy Isoflavones!" on the label, you have a different situation.

Eating a whole soy product, like soymilk, may maximize the effect. With careful laboratory analysis, you might even have a measurable effect. . . but probably not. More likely, you'll merely have a mild depression in incidence of certain ailments over a span of many years.

My protein powder says it has >95% isolated soy proteins. Doesn't mention isoflavones. Does this mean it does not, or may have them in it?
