B12 far too low

Tsh far too high though free could be a bit higher. T3 could be much higher and the low t3 could be the reson why tsh is raised.

If you increase the levothyroxine so that free t4 is top end of the range, you might start to convert more t4 into t3. If not, then you need some t3 or maybe ndt.

Hi Galathea

Many thanks for your reply and information. It is frightening these doctors that we rely on to keep us healthy they are a disgrace to their so called profession they want showing up!

I have seen my doctor this morning and he has agreed to send me to an endocrinologist so a bit nearer so not done anything with my current medication I.e 100 mg of thyroxine per day which is all I have been on for the past ten years but have felt really ill the last two years but all that has been put down to depression!

Anyway I will keep you and the rest of the forum advised as to my journey hopefully to success.

Have a lovely Christmas and a healthy New Year to everyone.

Hi Galathea

I went to my local Lloyd's chemist to ask for B12 and B9 I was asked what did I want it for quite aggressively I told her it is associated with my thyroid and that my B12 blood test read out was especially low. She told me the only way I could get B12 was through injections via the Doctor, I told her I had already seen the doctor and I am now waiting to see a cardo in February and didn't want to wait until then for treatment. She still wouldn't help me so I told her I am sick of so called professionals messing with my health when they don't know enough about the subject her reply was you can't expect us to be experts in all health matters I told her well it's about time something was done there are thousands of people suffering.

So I say sod em I have purchased both items off the internet.

The so called health professionals need to learn some empathy, gain some knowledge and listen to their patients.

Thank you very much for your reply and advice .

Take care and kind regards

B12 needs to be around a 1000 .....supplement 5000mcg Jarrow Methylcobalamin - keep under the tongue until dissolved. When levels are good then you can take the 1000mcg one. Only 20% of your B12 result can be utilised in the cells where it is needed so that makes the result even worse. Anything under 500 for a long period of time could result in neurological damage. Sadly Docs know very little about B12.

Hi Marz

Merry Christmas and thank you for your advice, please see my reply to Galathea for my current up date.

Thanks again



...what a strange reaction to a request for B12. Hope you soon feel stronger.
