Want to increase ferritin, but worried iron will get too high

My ferritin level is at the bottom of the range, and I really want to boost it. I think it will help me convert T4 to T3.

I know that it's dangerous for iron levels to be too high. Does anyone know if I can increase ferritin without increasing other iron levels?

My recent results:

Ferritin 58 (23.0 - 300)

Red cell blood count 5.09 (4.0 - 10.0)

Haemoglobin 138 (120.0 - 150.0)

Admin have suggested this: "If I have understood correctly, the ferritin does not transfer as fully formed ferritin from gut to bloodstream. It is broken down, passed across and the body does whatever it wants/needs with it.

However, I am most definitely no expert on iron and would be happy to be corrected."

Can anyone else help me on this one please?

TaraJR, if you supplement iron to increase ferritin it will also increase iron levels.


Ok, thank you. So if I try to raise my bottom of the range ferritin., will that be ok do you think? I really want the ferritin to help my T4 to T3.


TaraJR, it should be okay to supplement iron until ferritin is halfway through range unless you've had iron tests showing results high in range/over range.

I don't think your ferritin is bottom of the range. It isn't that bad, but some research has suggested that it isn't till it is over 60 that fatigue begins to lesson. I think you would nudge it up to 80 quite quickly and for you something like Spatone, which has a relatively small amount of iron, would be fine.

Ferritin is your storage iron.... kept till needed.


Eat chicken liver!


I recently started taking desicated liver pills (ordered from Amazon)with meals and that seems to help. I've not had a blood test since starting to see results though.


Possibly vitamin C. I have low ferritin and searchng for a vegan iron supplement on the vegan society website discovered that vegans are rarely low in ferritin because of insufficient iron in their diet but that it can be insufficient vitamin C. I supplemented with C for some weeks and my ferritin has risen from 15 to over 30.

Not sure if this would also work for a non-vegan but I can't think of any reason why not.
