B12 and Ferritin blood results - does my ferritin need to be higher than this for thyroid treatment?

I'm not on any treatment (yet!) but wondered if my ferritin needs to be higher in the range before any thyroid treatment? I had my blood taken a couple of weeks ago by my doctor - the results for B12 and ferritin are:

B12 436ug/L (>180)

Serum folate 16.7ug/L (4.6 - 18.7)

Ferritin 69ug/L (13.0 - 150.0)

I take the odd iron supplement now and again, but was a but unsure about taking too many. Do I need take it more often to increase this level??

Any advice much appreciated :)

  • Rough rule of thumb seems to be that it's good have ferritin half way up the range for optimal absorption of thyroid meds. Ferritin is the iron storehouse available to be called on when required and to dump excess iron circulating into the store. I'd be happy with your results but might eat a little more iron rich food.

  • Thank you clutter - that's reassuring to know :)

  • ferritin should be over 75 on that reference range so yours is nearly there

  • That's good, one less thing for me to worry about sorting then!
