Welcome to the forum Bluejohn

We are a helpful and supportive group and are here to help.

From your profile, I understand that you have not yet been diagnosed with a thyroid condition, nor have started any thyroid medication.

So we can offer better advice, can you tell us more about your thyroid health, eg ongoing symptoms, plus blood test results (with ranges in brackets) for:

TSH

FT3

FT4

Plus any antibody and key vitamin tests (ferritin, folate, vitamins D and B12)

In the first instance, do ask your GP for the above tests. We don’t recommend supplementing key vitamins without testing first (and sharing results with us).

If your GP is unable to complete all the above (eg if TSH is within range, some surgeries may not be able to access FT4 and FT3 tests), you could look to do this privately, as many forum members do, for a better picture of your thyroid health:

Regarding your question on key vitamins, I like my levels to be:

Vitamin D (100-150nmol/L)

Vitamin B12 (Total B12 at top of range or for Active B12 100 or above)

Folate (at least half way through range)

Ferritin (half way through range) Although some point to 90-110ug as optimal.
