Blood Results - Thoughts?

Suspect low T3 even though TSH and T4 in range (last test was 1.1 TSH 15 T4 same range, that was 4-5 weeks prior.)


Tested was fasted at 8AM. Also took my temperature under tongue just now as bought a thermometer, came out at 97.5 Farenheit which I believe is also low?

Test was sports hormone with medicheck, doctors notes said nothing of issue however don't trust that as thats purely based on it being 'in range'.

Anything suspect looking here as far as thyroid is concerned?

Sorry if it's a stupid question, but if you suspect low FT3, why didn't you get it tested?


Blame the brain fog. First post edited.

I've had a full thyroid panel done but that comes back next week or so, this one was a quicker turn around! Doh. That includes t3, rt3, antibodies


OK, well, nothing really jumps out of those results, except that your testosterone and FSH are a little low.

Your TSH is a bit on the high side, but your FT4 is mid-range, so it's possible that your FT3 is a bit low. We shall see! :D



I can't comment on all of them but the ones that stand out to me are

FOLATE (SERUM) 5.98 ug/L 2.91 - 50.00

This should be at least half way through range.

25 OH VITAMIN D 75.4 nmol/L 50.00 - 200.00

The Vit D Council recommends a level of 100-150nmol.

Could these interfere with t3 conversion?

Strangely my vitamin d on my doctors test 5 weeks ago came back right at top of range?! How odd?


I can't say for definite, certainly low Ferritin would but you have no problem there. Wait and see what results the other test shows, then you will know how well, or not, you convert.


Having low Vit D is 'good news', in the sense that you will likely feel an improvement in symptoms by raising it. Start with several thousand international units per day (5 or 6000) for a couple of months, and then go down to maybe 2 or 3000 long term. Get it retested in 6 months or so to make sure you're number is increasing. Also make sure you are taking vitamin K with it. I take thorne research drops, which contain both.

Folate I'm not sure on, you will have to search around. It seems strange to me for folate to be so low while B12 is pretty decent (they're both B-vitamins). But I don't know too much about B vitamins.


Does make me wonder if this low folate is a clue about the overall problem.


Is my D really that low then? It's strange because my NHS test 6-7 weeks prior came back right at the top of the range?

I will start supplementing it.

Although I suspect that alone can't be responsible for all of my symptoms? I'll have to look into it!!


It may be that the NHS test has a very low range, or 100 may be the top and 75-ish got rounded up to top. The Vitamin D Council recommends levels much higher than the NHS, which tends to be completely useless on vitamins. They will give the impression you can't be ill because of vitamin levels, but actually these have a big effect on your body.

It possibly could explain your symptoms. Low Vitamin D has very similar symptoms to low thyroid.

I've actually lost track of your overall symptoms. Do you feel very fatigued? Are you still able to do weightlifting and other intense exercise or have you had to stop that?


Having looked online at low vitamin d symptom, some line up (depression, fatigue) but ofc they are very general and can be linked to so many conditions. The more peculiar ones for vitamin d don't line up (excessive sweating, particularly forehead).

I'll definitely start supplementing to boost my levels, but equally I'd have to say I don't believe much of the problem will lie there, there are too many symptoms that would be explained by thyroid that vitamin d doesn't cover.

E.g. Dry skin, cold extremities, crazy fatigue and brainfog after eating goitrogens (this is the thing that really makes me think it's going to be thyroid, as I can't find any other explanation for that response), no sex drive.

But I'm sure if my D levels are not optimal it will not be helping matters!

My T3 arrived today (cytomel), as discussed previously I think I'm going to give that a go. Can I try it tho evening ? Or will it keep me up all night?


Also in answer to the exercise question, I haven't been to the gym for 2.5 weeks. I've just lost my general drive for anything, doing anything feels like too much effort ATM! I think physically I could work out if I wanted to, but I just feel so flat and have lost any sort of sense of motivation, I haven't bothered.

It's not a sad feeling, im just flat and apathetic. It's simply frustrating because I know isnt how life is meant to be!


Oh no, I just wrote a long reply to this, but my phone ate it :(

Short story:

T3 can either help with it hurt sleep. You can only try it it.

I suggest starting on a low dose, about 5mcg. You can always increase to tune it, but if you start high you won't kno whether to tune up or down.

If you're starting with T3, a good book is: Recovering with T3 by Paul Robinson


The T3 arrived, however they've sent me Tiromel!!! Even though it specifically said cytomel online.. grr. I've heard some people say Tiromel isn't as good - have you had any experience with it? Do you have a UK source for Cytomel without script?

I've heard a lot about that book, I think I need to check it out.


I dont think you can ever buy from the UK without a prescription. They're all overseas sites. I haven't tried any of the non-uk T3. But most people get on fine with all I think, it's only some people who find they're very sensitive to brands.


Ah yeah overseas I meant. Maybe the tiromel will be fine, hopefully as I got 100 tabs vs the 30 you get with cytomel.

I took half a tab (as no pill cutter and it has a half break line l) so 12.5mcg 20 minutes ago . Nothing to report yet. Now I pray!


Most sites that sell liothyronine/T3 without a prescription use the name "Cytomel" - I assume that the majority of those searching type that in as a search term.

Some even quite clearly show a photograph of the make they will supply - I've seen that particularly with Grossman Cynomel. That is, I don't think they are meaning to be deceptive - just to get the web traffic.

Some will, of course, will simply be lying.

And few will actually be selling Pfizer Cytomel.


It's funny because it clearly said 'Greek Cytomel'.. I emailed the guy and asked why I'd recieved Tiromel. His response was "I sent you the better one, Tiromel is twice the price" and went on to say he can exchange it for Cytomel if I want..

What a joker lol. I forgot that in effect drug dealers were so generous these days, and actually wanted to cut their profits to help customers they've never dealt with before!

It's been 2 hours since I took 12.5mcg, I'm not sure I've felt any effect. Possilbly mild, possibly placebo.

Does this mean its unlikely to be low T3 as my issue? Or is it just that sometimes T3 takes longer to respond in some people? I was hoping I'd been one of those people that takes it, and then suddenly feels the symptoms lift 30 minutes later! :(


I'd have expected "Greek Cytomel" actually to be Uni-Pharma liothyronine!

Sorry - no personal experience of liothyronine - of any make. But we are all different so I'd not be too concerned or surprised. Just don't go mad and decide that as 12.5 did so little you will try 50... Slowly, carefully, patiently.


Now I'm confused... I thought Uni-Pharma was Cytomel? Or is it not?

Is Liothryonine T3? The Tiromel I have is "LIOTHYRONINE SODIUM".

I will try 12.5mcg again tomorrow, totally fasted, and see if I notice anything. And then maybe try another 12.5mcg 6 hours later?


Liothyronine (most often liothyronine sodium but sometimes liothyronine hydrochloride) is the active ingredient - also called T3 or triiodothyronine.

As a medicine, King Pharmacuticals Inc. (KPI) were makers of a brand of liothyronine sodium called Cytomel (they bought another company but I cannot remember their name!)

Pfizer bought King.

Cytomel tablets are marked with KPI on one side because of that link.

There are some other branded liothyronine products: Sanofi Henning Thybon, Sanofi Cynomel, Grossman Cynomel, Abdi Ibrahim Tiromel as examples.

There are other generic liothyronine products from many companies.

In some countries, Pfizer do not own the brand name Cytomel so other companies sell their product under that brand name. (I think the Netherlands is one such country.)

If it doesn't say Pfizer Cytomel - and probably also claims it as a product from the USA - it almost certainly won't be Pfizer Cytomel.

Don't be so impatient!!!!! On your second day you are thinking of doubling your dose? And doing so on the basis of six hours of experience tomorrow morning.

I wrote: Slowly, carefully, patiently. I did that for a very good reason.

Sorry, I'm just feeling so crappy and desperate. I'll stick to 12.5mcg again tomorrow.

I've also just ordered Regenerus's adrenal test, as I think that would be wise to check also.

We have seen so many people feel just like that - a bit more, a bit faster, it can't be any worse than I am feeling now. We have also seen so many people wish they hadn't gone mad and raised their dose too quickly.

I just don't want to see another person coming back and say they wish they hadn't gone so fast. :-)

I know you're right.

Will Regenerus send me the result directly do you know? I just ordered the test and hadn't thought - or do they require it to be via a practioner?
