So many people are told “your labs look fine” once they’re on T4 medication — yet they can still feel flat, foggy, tired, puffy or stuck with weight that won’t shift.
Here’s the part that often gets missed:
T4 is only a pro-hormone. Your body still has to convert it into active T3 for it to actually work.
And that conversion depends on things like:
-Nutrient status
-Liver and gut function
-Stress and cortisol levels
-Muscle mass
-Inflammation
-Blood sugar balance
If those pieces aren’t supported, you can be “on medication” and still feel unwell.
Medication can be essential — but it’s rarely the whole picture.
If you’re still symptomatic, that doesn’t mean you’re failing treatment.
It usually means your body needs more support around it.
A little bit of work and digging around why your body is presenting with certain conditions and giving it the support it needs, can go a long way for better health.
