Let’s keep it real simple 👇
Hormones? Fat-soluble. They don’t swim free in blood—they hitch a ride on SHBG (Sex Hormone Binding Globulin).
Think SHBG = your hormone’s Uber / FedEx truck 🚚
Labs measure the trucks on the road (total hormones).
But most are bound—locked in the truck, can’t get out.
Only the free hormone (~2%) jumps off, enters tissues, and actually does the work: energy, mood, metabolism, libido.
Here’s the game-changer:
If free hormone bumps from 2% → 3%?
That’s a 50% jump in real tissue action…
while total blood levels look “normal.” 😶
Blood shows transport.
Symptoms show tissue function.
That disconnect? It’s why you feel off even when labs say you’re fine. Midlife isn’t decline—it’s time for clarity on what’s bioavailable.
