Stuff Your Doctor Should Know

#281 When “Healthy” Makes You Feel Awful:


Listen Later

In this episode, Kitty is joined by Dr. Tyler Panzner, a pharmacologist who specializes in how nutrients, supplements, and hormones actually work in the body.

Together, they unpack a question so many people are quietly asking: Why do supplements and hormones help some people—but make others feel worse?

Dr. Panzner explains, in plain language, how supplements often have multiple effects at once, why genetics can change how your body responds, and why feeling “wired,” anxious, groggy, or overstimulated isn’t random—or a sign that you’re broken. They explore common examples like quercetin, melatonin, vitamin D, and estrogen, showing how the same intervention can be supportive for one person and problematic for another.

The conversation also dives into hormone therapy headlines, including the removal of the FDA black box warning on estrogen, and why “safe for everyone” is never a biologically honest statement. Kitty and Dr. Panzner discuss estrogen metabolism, detox pathways, genetics, and the growing gap between real-world patients and one-size-fits-all medical advice.

This episode is about nuance, personalization, and self-understanding—not fear, dogma, or extremes. If you’ve ever felt confused by conflicting health advice, overwhelmed by supplements, or frustrated that “doing everything right” still isn’t working, this conversation will help you make sense of why.

Topics discussed:

* Why the same supplement can feel amazing for one person… and awful for another (it’s doing more than you think)

* “Hidden side effects” of supplements: the part nobody talks about (the iceberg under the water)

* Quercetin example: great for allergies for some, but can make others feel wired, anxious, or “amped up”

* Genes 101 in plain English: “variant” vs “mutation” and why it doesn’t mean you’re broken

* The “wired but tired” type: why some people get overstimulated easily and don’t “clear” stress chemicals well

* Why humans even have these weird quirks: how certain traits may have helped our ancestors survive

* HRT and safety claims: why “it’s safe for everyone” is never true, even if headlines say it is

* Estrogen breakdown made simple: how your body processes estrogen—and why some people recycle too much of it

* Why doctors don’t test everything: the gap between real life and research studies (and insurance limitations)

* Melatonin: why it helps some people sleep like a baby… and makes others groggy, dream-crazy, or lowers libido

* Vitamin D: why some people don’t respond to the usual kind—and why blanket “never take vitamin D” advice can backfire
