In other words, bio-identical hormones have been with us for years.
What are the differences between
bio-identical hormones and synthetic ones?
Bio-identical hormones are identical to hormones our bodies make. They talk to cells through specific receptors that are made for them. For example, bio-identical estradiol (a type of estrogen) in patch form, gel or cream (brand names: Estragel, Estradot, Tri-Est, Bi-Est) acts just like the estradiol our ovaries secrete into the bloodstream.
