Your thyroid medication isn’t working because your GUT is the problem.
Let me explain. 👇 80% of people with hypothyroidism have gut imbalances that directly impact thyroid function.
Here’s what’s happening: Your gut microbiome is responsible for converting inactive T4 into active T3 (the hormone your cells actually use).
When your gut bacteria are imbalanced, this conversion can drop by 30%. That means even if your TSH looks “normal,” your cells are still starving for usable thyroid hormone. This is why you’re still exhausted, bloated, and gaining weight despite taking medication.
What actually helps:
✅ Eat 25+ different plants per week (fiber feeds gut bacteria)
✅ Add fermented foods if you tolerate them (probiotics)
✅ Include zinc & selenium (pumpkin seeds, Brazil nuts)
Your thyroid and your gut are in constant communication.
You can’t fix one without addressing the other.
