Hi Jennie :)
Yes our nutrition tutors tell us the same thing, to eat flax, and though I know it's a very good oil, there is the oestrogen factor which they've never mentioned to us!
I'm sure Shelley says that if you take it with other oils like in Udo's then it would less of an estrogenic effect, though having said that Udo's has evening primrose oil in it which I hear is also estrogenic! How confusing!
I normally take borage oil. It's Biocare's high GLA (about 700mg) with vitamin E and lecithin and I find that helps.
Perhaps taking a tablespoon of flaxseeds a day wouldn't affect estrogen levels too much and if you keep up with liver and bowel cleansing that should help too.
Have a good weekend!
