Dear doctors,
I have to tell you something I wish someone had told me twelve years ago. Biest is bull$hit.
I know. I know. You were trained to use it. You read the same functional medicine textbooks I did. You attended the same conferences where someone explained, with great conviction and a colorful receptor diagram, that estriol is “breast protective,” that it “balances” the estradiol, that combining the two gives your patients the best of both worlds. I drank that same Kool-Aid. For the first two years of my hormone practice, I prescribed Biest to patients. I ordered salivary and urine tests. I gave tiny, carefully calibrated doses. And I was, without realizing it, failing the women sitting across from me.
Let me explain what Biest actually is, and why the logic behind it falls apart the moment you poke it.
P.S. If you want my sources but don’t want to pay for the article below, HERE is a list.
