How is bioidentical hormone replacement therapy different from synthetic HRT?


Hormone replacement therapy (HRT) is the term generally used when referring to synthetic hormones, such as Premarin and Prempro. These drugs have been used for decades to “replace” the hormones that fluctuate and begin to decrease when women enter perimenopause and menopause. Synthetic forms of progesterone and estrogen are not natural replacements for our bodies’ own hormones, however. Premarin is estrogen derived from the urine of pregnant mares, conjugated with synthetic forms; Prempro is Premarin in combination with a synthetic form of the human hormone progesterone.

The term bioidentical HRT, on the other hand, refers to hormone replacement molecules that are biochemically identical to those we make in our bodies.
