Good Morning.

Any advice welcome regarding T3 levels.

T3 3.2 ( 2.6-5.7) pmol/l

FT4 15.5 (9-19)pmol/l

THS 0.09 (0.35- 4.94) mu/l

Vitimin D 85 (71-200nmol/l)

I had a thyriod removal this year, should I be taking T3/T4 combination? I'm prescribed T4 only.

T4 reduced as previous levels were (0.03)(0.06) now at 0.09 to which I feel better.

Could you edit your post Ness21 to add your TSH and T4 too (with ranges) as this will help members advise.

Why did your endo reduce your Levo from 100 to 75mcg?

Have you had key vitamins tested (Vit D, ferritin, folate, B12)? Having these optimal will really help.

Re adding T3, it’s important to get key vitamins & Levothyroxine dose optimal first before going down a combination route (if needed).

What are your current symptoms?

Thankyou for your reply I've update my post with the levels.

It wasn't a endo it was the surgeon who reduced meds, as i had headaches stomach cramps sweating couldnt sleep and my THS was at 0.03, 0.06.

It's now 0.09 I feel better now than I have in a long time.

He said I didn't need my THS to be suppressed as the cancer was only a trace which was a accidential find, it hadn't spread and was removed with the thyriodactomey.

I had chronic thyrotoxicosis and a 5cm grioter/ mass which was removed.

I'm feeling alot better the above symptoms have disappeared, however I still feel tired in the early afternoon.

I would definitely test key vitamins, as having these higher in range boosted my energy and improved my overall health. I test privately (eg Medichecks- which are often discounted on Thursdays), then post results on the forum for advice re supplements. It’s important to get these optimal before considering adding T3.

Suppressed TSH isn’t necessary a problem if T3 and T4 are in range. Many medics panic about this, whereas more enlightened & knowledgeable practitioners understand.

Thankyou for your reply

What are the key vitamins? I know vitimin D.

Buddy195 profile image
Buddy195Administrator in reply to Ness21

Folate, ferritin, Vit B12 and Vit D are all key for thyroid health. Please don’t supplement before testing.

Ness21 in reply to Buddy195

Thankyou. I will call the doctor and ask for them to be checked.

Buddy195Administrator in reply to Ness21

If GP won’t test (some don’t) look into private home testing & post results on the forum for advice.

I checked my medical records app, it states I had the vitimin panel tested in 2018, I should recieve a call from the doctors on Monday regarding retest. Should I ask for a celiac test?

Previous post

Weight 82kg

THS 0.09 (R) 0.35 - 4.9 MU/L

FT4 15.5 PMOL/L (R) 9-19

FT3 3.2 PMOL/L (R) 2.6-5.7pmol/L

Vitimin D 85NMOL/L (R) 71-200

So you are on Teva as lactose free suits you better

Are you also on lactose free diet

Have you had thyroid antibodies tested?

Lactose intolerance suggests autoimmune thyroid disease also called Hashimoto’s diagnosed by high TPO or high TG thyroid antibodies

Also ESSENTIAL to regularly retest folate, B12 and ferritin

Night sweats often low B12

At 81 kilo the guidelines on dose by weight is 130mcg daily, so 75mcg is unlikely high enough

It’s common phenomenon that when dose levothyroxine is initially reduced, many people feel better initially. Lower Ft4 possibly results in better conversion of Ft4 to Ft3. And/or adrenals are less stretched

But eventually hypothyroid symptoms return

Bloods should be retested 6-8 weeks after any dose change or brand change in levothyroxine

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.

Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis) or if under medicated

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Is this how you do your tests?

Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins

Thyriod antibodies 20ku/l (0-40kul)TG 28g/l (20-35g/l)

Tyroglobium 1.1 (0-40ugl)

RDW 11.4 (11.6-14%cv)

I was diagnosed with graves disease however I feel better when I eat less lactose.

I'm have a blood test in three weeks for THS, T3 FT4.

This is all new to me and I'm just a bit lost with it all.

Both Graves and hashimoto’s patients are often gluten intolerant and/or lactose intolerant

Important to test vitamin levels regularly

Ness21 profile image
Ness21 in reply to SlowDragon

Thankyou, I'm going to ask doctor if he will test my vitimin levels.

SlowDragon profile image
SlowDragonAdministrator in reply to Ness21

Unlikely to do so, but always worth asking

If not, test privately 6-8 weeks after dose reduction in levothyroxine

Always test as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test

Aristo is an alternative lactose free levothyroxine, but only available in 100mcg tablets.

Can cut into 1/4’s to get 25mcg

Ness21 in reply to SlowDragon

I spoke with the doctor, they won't do my vitimin testing, she said my tyroglobium ( I think that was what she referd too) was fine when tested in July. It seems I'm going to go private testing, however I have my thyriod panel being done today THS T4 T3 and reverse calcium.

SlowDragon profile image
SlowDragonAdministrator in reply to Ness21

So next step is to get FULL thyroid and vitamin testing done

Only do test after minimum 6-8 weeks on constant unchanging dose and brand of levothyroxine

Only do private testing early Monday or Tuesday morning and then post back via tracked postal service

Always test as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test

What vitamin supplements are you currently taking

If taking any supplements that contain biotin stop these a week before all blood tests as biotin can falsely affect test results

If testing iron/ferritin levels, stop any iron supplements a week before test

Come back with new post once you get results

Ness21 profile image
Ness21 in reply to SlowDragon

Thankyou

I'm only taking vitimin D.

SlowDragon profile image
SlowDragonAdministrator in reply to Ness21

When supplementing vitamin D test twice year

How much vitamin D are you currently taking

Test others - folate, ferritin and B12 at least annually

Most U.K. patients forced to test privately via Medichecks or Blue horizon

Come back with new post once you get results

Ft4 65% through range

Ft3 19% through range

Helpful calculator for working out percentage through range

Ness21

Thankyou.

What percentage should they be? I have no idea.

SlowDragon profile image
SlowDragonAdministrator in reply to Ness21

Most people when adequately treated will have Ft3 at least 50% through range, sometimes need higher at 70% plus

Usually on levothyroxine only need Ft4 higher % than Ft3 in order to get Ft3 high enough

Optimal vitamin levels help tolerate higher doses levothyroxine

So getting vitamins optimal helps and can reduce symptoms

Always worth trying strictly gluten free diet too, especially if lactose intolerant

Lactose intolerance often improves on strictly gluten free diet

If can’t tolerate high enough dose levothyroxine then looking at adding small doses T3 prescribed alongside levothyroxine

Thankyou.

I don't have milk, I have small amounts of butter, rarely have cheese/ dairy products.

It's strange the less food I eat the better I feel, however still stones over weight.

Hello Ness :

A fully functioning working thyroid would be supporting you daily with T1. T2 calcitonin plus approximately 10mcg T3 + approximately 100 mcg T4 .

T4 - Levothyroxine is a storage hormone that needs to be converte by your body into T3 the active hormone that the body runs on and is said to be about 4 tims more powerful than T4 with the average person needing to find find / convert / utilise around 50T3 daily to function.

Your ability to convert the T4 into T3 can be compromised by low viamins and minerals and we need ferritin, folate, B12 and vitamin D to be maintained at optimal levels to assist in the thyroid hormone conversion.

The thyroid is a major gland responsible for full body synchronisation including your mental, physical, emotional, psychological and spiritual well being, you inner central heating system and your metabolism.

It is essential that your dosed and monitored on your T3 and T4 blood test results and not your TSH, though in primary this maybe all you find is being actioned, read or understood.

We generally feel at our best when both these vital hormones are balanced, within the ranges, and with your T4 in the top quadrant of the range and over 75% as this in theory gives a better, higher T3 reading.

Currently your T3 is coming in at around 19% with your T4 higher at around 65% and I see your dose of T4 has been reduced so not sure if this has to yet impact on this result.

The accepted level of conversion when on T4 - Levothyroxine only is 1 / 3.50 - 4.50 - T3/T4 :

with most people feeling at their best when they come in at around 4 or under ;

So, to find your conversion ratio you simply divide your T3 into your T4 and I'm getting 4.80 showing your conversion struggling and going out from centre.

It could still be " early days " as I'm not quite sure now, when you actually had your surgery.

I too have Graves but I was treated with RAI thyroid ablation in 2005.

I have found the Elaine Moore Graves Disease Foundation website a very useful adjunct as to understanding Graves, as it is poorly understood and bdly treated auto immune disease.

I found I also needed to learn about the thyroid and all that it does and found the following book written by a doctor who has hypothyroidism and excellent " go-to " :

Your Thyroid and How To Keep It Healthy by Barry Durrant-Peatfield -

I know it sounds counter intuitive but we do need to know all that it does, just so we can try and compensate accordingly.

Hey there Ness ;

Nobody except me is going to see this new post tagged on the end of what is considered an " old " post:

Whilst I maybe flattered, you deserve more than my eyes, and suggest you repost the above as a new post where everybody is able to help and give advice.

People will look back at your previous posts if they need to - don't worry :

I'll reply on the new post, so it's all together, and I also don't know all the answers :

See you on the " other side " :
