T3 & T4 - What is optimum?

HypoCrazy profile image
13 Replies

Please tell me if these results are ‘healthy’ for a hypo patient, with respect to T3 & 4 levels :)

TPO antibodies 91 iu/mL

T3 5.0 (upper part of range 6.8)

T4 18.8 (range 10.60-23.30 pmol/L)

TSH 0.34 (0.3-4.2 mU/L)

Has anyone else had this combo - high B12 and low folate?

B12 793 (197-771)

Folate 10.7 ug/L (3.9-25.80 ug/L)

Some people would find those levels optimum for them, others wouldn't. They wouldn't be for me. The aim of a treated hypo patient generally is for TSH to be 1 or below or wherever it needs to be for FT4 and FT3 to be in the upper part of their respective reference ranges when on Levo if that is where you feel well.

It depends how you feel and you haven't said. Are you still symptomatic - this is what is important.

I had a similar B12/folate combination when I tested everything 3 years ago. B12 was top of range, folate was 6.9(4.6-18.7). I raised my folate level quite quickly with Thorne Basic B and use a maintenance dose now.

Hey Seaside

Thank you. Did you find the high B12 was contributing to poor sleep and acne? I’m seeing reports online and wonder if that’s at the heart of my sleep issues. Were you able to get your B12 down quickly? I read it can lurk for up to a year in the liver!

P.S. I’m a bit cautious about resuming my B Complex as it also contains B12...

Many thanks

I've had my B12 well over range, as high as 1509

with supplements (I cut back after this result) and for me it didn't make any difference to my sleep and I've never suffered from acne.

400mcg B12 in a B Complex is a small amount, probably classed as a maintenance dose. That's basically what I rely on now to keep my level where it's recommended to be for my age which is, according to an extract from the book, "Could it be B12?" by Sally M. Pacholok: "For brain and nervous system health and prevention of disease in older adults, serum B12 levels should be maintained near or above 1000 pg/ml."

My B Complex states 100ug of B12 as Methylcobalamin. Is that a high dose or just a maintenance one? 🧐

It's very low and would probably be fairly insignificant. But as your B12 is top of range, it will probably be fine for you.

Mine contains 400mcg and I take my B Complex 5 times a week.

Hiya Pascha

I feel pretty terrible - my eyes ache and I can’t sleep more than 2-3 hours at a time. Please let me know if you have any advice for me :)

Hi randleiv

Please post your own question in a new thread. That way it will be at the top of the forum page where everyone will see it and you will get more answers, rather than being tucked away in someone else's thread much further down the forum where it will be missed. It also helps keep HypoCrazy's own post on topic.

hi Grincho - no I’m not. I always have a terrible night’s sleep if I do and a kinesiologist confirmed that my body doesn’t really like magnesium supplements. Have you had this experience?

Hi Grincho, am I right in thinking you’re way out of range by being so high at 1200?
