Lot of the NBE supplements are basically food, stuff that is right there in things we eat, but obviously concentrated.... I think there's a whole lot of benefit to this, maybe not a dramatic night and day difference, but eating the right kind of foods will support estrogen dominance and healthy hormone balance so of course its a great idea. And then there are things that can drastically alter for example prolactin levels. Eat oats, barley and hops, those three are all breast food.
I really love my oatmeal, oat + barley breads and very hoppy beer. ^_^
