A lab result can come back “within normal range” and you can still feel far from your best.
That’s because standard reference ranges are built from population averages, not from what’s optimal for you.
A few examples:
- TSH “normal” can span a wide range, even when thyroid symptoms are present
- Ferritin can be “normal” but still too low for energy and hair health
- Vitamin D can clear the bar and still be insufficient for immune and hormone function
Root-cause care looks at where you fall in the range, not just whether you’re in it, and how that connects to how you actually feel.
Wondering if your labs are telling you the full story?
Let’s take a closer look.
