95: Hormone Replacement Therapy Myths and Truths With Dr. Anna Garrett

In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews pharmacist and menopause expert Dr. Anna Garrett to unpack the biggest myths – and most misunderstood truths – about menopausal hormone therapy. Together, they explore what hormone therapy looks like today, why many women were unnecessarily frightened after the Women’s Health Initiative (WHI) study, and how modern options (like transdermal estradiol and micronized progesterone) are changing the conversation. They also discuss why progesterone can be a game-changer for sleep and mood in early perimenopause, why estrogen becomes more important later on, how testosterone supports strength and vitality, and why testing and metabolism pathways (including gut and histamine factors) can influence results. What you’ll learn in this episode: Why the “hormones cause cancer” narrative won’t die despite a flawed WHI study. Dr. Garrett explains how the Women’s Health Initiative used older products (like conjugated equine estrogens and synthetic progestins), and why today’s bioidentical options have a very different risk/benefit profile. She also shares the resource that helped her advocate for herself – even with a strong family history of breast cancer. Progesterone supplementation can be a smart starting point, even for mid-30s hormone chaos. If you’ve suddenly developed insomnia, anxiety, mood swings, or “crime scene periods,” it may be a sign you’re ovulating less frequently (and losing that calming progesterone effect). Dr. Garrett talks about why progesterone alone can be a smart starting point for many women. When progesterone stops working for sleep, this may point to a drop in estrogen. Dr. Garrett shares how low estrogen can become a bigger driver of sleep disruption in late perimenopause/menopause, and why combining estrogen and progesterone can be the “lights back on” moment for some women. Testosterone isn’t a “male hormone” – and dismissing it can cost women strength and vitality. Dr. Garrett shares why testosterone matters for muscle maintenance, bone health, drive, and overall wellbeing… plus why pellets can be risky if you haven’t dialed in your dose. The DUTCH test and hormone pathways: why metabolism matters as much as dosing. Even bioidentical hormones can create unwanted effects. Dr. Garrett walks through tools and nutrients used to support healthier estrogen/testosterone metabolism – and why these tests are best interpreted with a trained practitioner. How to decide if hormone therapy is right for you (without needing a medical degree). They talk candidly about “shared decision-making,” quality of life, clotting risk considerations, transdermal estradiol vs oral estrogen, micronized progesterone, and experimenting with HRT to see if it’s right for you.
