How to Spot That Your T2 Conversion Is Low (Even If Labs Look Normal)

TL;DR:
You can have “normal” thyroid labs yet feel fatigued, cold, and stuck at the same weight. T2 isn’t usually measured, but it’s vital for cellular energy and metabolism.

Common Signs of Suboptimal T2 Activity

• Persistent fatigue or sluggishness
  
  

• Cold hands and feet
  
  

• Stubborn weight loss plateaus
  
  

• Brain fog or low mood
  
  

• Low waking body temperature
  
  

Why Labs Can Miss It

Most thyroid panels include TSH, T4, and sometimes T3—but not T2, because there isn’t a test for T2. That means your cells may be under-energized even though your lab results look fine.

Factors That May Reduce T2 Conversion

• Chronic stress and high cortisol
  
  

• Deficiency in selenium, zinc, or iodine
  
  

• Crash dieting or prolonged calorie restriction
  
  

• Liver sluggishness or toxin load
  
  

• Poor sleep or systemic inflammation
  
  

What You Can Do

• Eat enough protein and micronutrient-rich foods.
  
  

• Reduce stress and get regular restorative sleep.
  
  

• Hydrate well and include cruciferous vegetables for liver health.
  
  

• Consider nutrient-dense thyroid-metabolism support that helps provide key cofactors and adaptogens.

• Add in Thyroid Fixxr or Metabolism Fixxr to increase T2
