Maybe you’ve already done the work: You ordered the comprehensive panel, you found out your thyroid is underactive, you even started supplements or medication. But you’re still tired, still cold, still gaining weight without explanation.
These days, it’s easier than ever to test. You can run labs through a trendy blood panel service and get pages of data delivered to your inbox. But data without interpretation isn’t care, and if no one’s looking beyond your bloodwork, they’re missing half the story.
What most of these reports don’t include is what we almost always find:
Your thyroid might be underactive — but your gut is the reason why.
About 20% of your active thyroid hormone (T3) is converted in the gut. When the gut is inflamed, sluggish, or imbalanced, that conversion breaks down... no matter how much T4 is circulating in your system.
The gut is also where you absorb the nutrients your thyroid needs to function: selenium, zinc, iodine, iron. If you’re not digesting or absorbing well, your thyroid is undernourished.
And when the gut lining is compromised, it can disrupt immune regulation and drive autoimmune thyroid conditions like Hashimoto’s long before your symptoms match the textbook.
This is why we don’t just run a full thyroid panel. During your first few visits, we also run a comprehensive stool test. After thousands of patients, we know real answers don’t come from treating lab values but rather they come from understanding how the systems behind them are working.
When the gut is supported, the thyroid often follows. Not because of one supplement or protocol, but because the right pieces are finally being addressed in the right order.
