My OBGyn tried to give me the synthetic hrt to me. Gosh, no way. Thankfully I have experts that know about Bio Identical hormones and that is takes more than just estrogen and progesterone. My bio identical hormones help every part of the body, including stopping my many years of migraines. So good for eye health, brain etc. I am so thankful for doctors that actually do know how to heal, and safely!
