You are taking levothyroxine tablets -- Levoxyl®, Synthroid®, Unithroid®, or generic levothyroxine -- and still don't feel well...and you have a high intake of soy foods and/or supplements.
WHAT COULD BE GOING ON?
A diet high in soy foods – or use of high-concentration soy supplements – can interfere with your ability to absorb levothyroxine tablets effectively.
ACTION PLAN:
You can cut down on your soy consumption as a key first step. Also, note that soy supplements frequently have very high concentrations of soy isoflavones which can interfere with your absorption. If you are still having issues, you may want to switch to Tirosint® or Tirosint®-SOL, which are better absorbed, and more resistant to the negative effects of soy on levothyroxine absorption.
