BioIdentical Estrogens
Human females produce primarily three estrogens. Estrone (E1), estradiol (E2) and estriol (E3). These estrogens are often prescribed in various combinations to re-establish an individual's normal balance.
  • E1 is the primary hormone produced after menopause normally it represents 10% to 20% of circulating estrogens.
  • E2 is the most potent estrogen and is produced by the ovaries. E2 is the predominant estrogen produced before menopause. E2 is 10% to 30% of circulating hormones.
  • E3 is the least potent estrogen and is produced in large quantities during pregnancy. It is thought to be protective against breast cancer and E3 causes little or no build up of the uterine lining. E3 has been shown to be effective for the treatment of menopausal symptoms and postmenopausal problems, including vaginal dryness, vaginal atrophy, painful intercourse as well as problems such as urinary incontinence.
