Please would someone have a look at my medichecks results and see if I have a conversion issue? I’m on 100mcg of levothyroxine and am steadily gaining weight (30lbs in the last 12 months). I’ve worked out that I’m 51% through the T3 range and 86% through T4, but not sure if they should be similar?
I’m considering NDT as really not feeling myself.
When you posted 7 months ago your Ferritin was low - this can affect your conversion. Are you still supplementing ?
Yes, I take 210mg ferrous fumerate a day as well as 4 x desiccated liver capsules.
Have you had a recent re-test for Ferritin ? Do you take VitC to aid iron absorption ? Full Iron Profile test ?
Last blood tests were in Feb (apart from the medichecks). Yes, I either take a vitamin C tablet with the ferrous fumerate or a glass of orange juice if I'm out of tablets.
So how was your Ferritin last time ? Regular testing important as too much can be as bad as too little !
This conversion rate is normal. That's not to say you might benefit from some T3.
Ft4 was 86% through range
Ft3 only 51% through range

Getting all four vitamins optimal and strictly gluten free diet often helps or is essential
Do I have a thyroid problem? 
Latest thyroid results, may have conversion problem.
I have normal Iron but low Ferritin, can this still cause conversion problem T4 to T3?
If I Don't Have a Conversion Problem, Could NDT or Adding T3 Still Work for Me?
