I posted my blood results here a while ago and got advised to get b12 etc to top of range ( was 704 in range of 180-914)

I've been supplementing along with folate & iron.

Apart from being exhausted I'm still so breathless . has anyone else had this ?

I feel some days as if my chest is heavy - almost like a weight on it.

My other results were vit d 94 ( 50-150)

Folate 6.6 (2.70-34.00)

Ferretin 62 (20.00-275.00)

Thankyou !

Your ferretin level is too low. In the range that you quote you would need to have a level of approximately 130 to be mid-range - i.e. double what your level currently is.

Since your ferretin is too low it might mean that you are anaemic. Ferretin can be inflated by inflammation and give a false picture of what your iron status really is. You don't have enough information to get a full and accurate picture though. For that you would need a full iron panel done and a full blood count too.

I had ferritin which was only just in range, and severe breathlessness was one of my symptoms. It has improved since I started taking iron supplements 15 months ago, but progress is slow.

What kind of iron supplements are you taking, and at what dosage?


Same here. The best relief that I've ever had is from a B12 injection. Unfortunately, the doctor who let me have one as a trial then claimed that the effect was placebo. I'm now locked in a battle to get properly tested for B12 deficiency.

My B12 serum level is 500 , and I've been taking B12 supplements in high does for years but it makes no improvement.
