If you don't believe me then listen to Oprah:
"After one day on bioidentical estrogen, I felt the veil lift," Winfrey writes. "After three days, the sky was bluer, my brain was no longer fuzzy, my memory was sharper. I was literally singing and had a skip in my step."
That's pretty much what it's like too. You might feel a little medicated at first, but that's because the drugs needed to supress your testosterone are kind of grouchy until you get used to them. With bioidentical estradiol, once that passes you just feel, dare I say it, normal. It's the most fabulous thing, and there really aren't words to do it justice. You'll marvel at simple things which you never noticed before because of your testosterone dulled senses and emotions; the greenness of grass, the sound of a seagull, I even noticed smells in the wind that I hadn't before.
Don't mistake bio-identical for herbal, and stay out of the horse pee. Bioidentical estradiol isn't as hard on your liver, in fact being micronised you can dissolve it under your tounge and really give your liver a break while increasing the effectiveness at the same time. There's a lower risk of clots and depression and just about everything really. The same holds true on paper for bioidentical and micronised progesterone if you choose that path, I personally haven't used it (yet) so I can't vouch for it.
So to answer the question, yes bioidentical is the good stuff.
