Dear Community

I have recently undertaken blood test, with the attached results.

i have Autoimmune Thyroiditis (Primary Hypothyroidism) and Primary Hyperparathyroidism.

Autumn 2022 I felt things were going back to how they were in the early days - headaches, weight gain despite exercise and controlled diet (also experimented with gluten free etc), nails easily chipping, hair loss...

Had several conversations with my GP who basically said there is no reason to change any dosage and that he simply wasn't going to raise it. I asked for bloods to be repeated because my TSH had jumped from 0.52 in Sep 2022 to 3.27 in Nov 2022. ft4 and ft3 were not tested at that time.

I found in my pile of medical paperwork an old blood test form where a previous endo had asked for ft3/ft4 amongst other tests so I took that to the hospital and bloods were taken. The results are attached. I have also plotted all the tests that i have had over the years since i was first diagnosed. Some of the bloods tests look similar but i have copied the titles as per the information on my patient knows best app - sorry if the mean the same thing. I just didn't want to assume.

I've never paid too much attention to what brand I had been given in the past and maybe this is what caused the jump from 0.52 to 3.27. Now I am paying attention and had a few old empty boxes which were largely the Accord brand. And still taking Accord. May be i need to change ? i'm not sure what to do.

I was scheduled to have a meeting with my endo this month but was notified in October that it had been pushed forward to April. I emailed my endo twice but received no reply.

I was desperate to get things under control and increased my dosage in Nov from 100mcg to 125mcg - initially taking 112.5mcg for a week and then 150mcg on one day and 100mcg the next day to achieve a 125mcg daily intake.

I had a strip of the Accord Levo and used that to supplement the increase - they only come in 100mcg tablets because that is officially what I should be taking, so have been using a tablet splitter which i purchased off Amazon. It's not precise but I guess its better than crushing the tablet.

The problem is, I'm not sure if I am feeling better or not. I am experiencing aches / pain in legs but they are not swollen. I've had this once before a few months ago and it lasted a couple of days. Now, its almost every day. Even if I am lying down or my feet are up i feel as though the aches and pain are going to make my legs give way. It is difficult to muster up the will power to get up and carry on with day to day things. Its as if the legs are going to stop working. I have never experienced this before and can't be certain if this is as a result of increasing the dose from 100 to 125.

Difficult to read the table

But vitamin levels

Nov 22

Vitamin D 59nmol

This was too low

How much vitamin D are you now supplementing

Feb 23

B12 far too low

No folate result

Suggest you start supplementing separate B12 initially

Then after 2 weeks add a daily Vitamin B complex

Low B12 symptoms 

b12deficiency.info/signs-an...

methyl-life.com/blogs/defic...

With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a B12 supplement as well as a B Complex 

Then once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.

If Vegetarian or vegan likely to need ongoing separate B12 few times a week 

B12 drops 

healthunlocked.com/thyroidu...

B12 sublingual lozenges 

amazon.co.uk/Jarrow-Methylc...

cytoplan.co.uk/shop-by-prod...

B12 range in U.K. is too wide

Interesting that in this research B12 below 400 is considered inadequate 

healthunlocked.com/thyroidu...

good quality daily vitamin B complex, one with folate in (not folic acid) 

This can help keep all B vitamins in balance and will help improve B12 levels too

Difference between folate and folic acid 

chriskresser.com/folate-vs-...

B vitamins best taken after breakfast

Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule) 

Thorne currently difficult to find at reasonable price, should be around £20 

If you want to try a different brand in the meantime, one with virtually identical doses of the ingredients, and bioavailable too, then take a look at Vitablossom Liposomal B Complex. Amazon sometimes has it branded Vitablossom but it's also available there branded as Yipmai, it's the same supplement

amazon.co.uk/Yipmai-Liposom...

or available as Vitablossom brand here

hempoutlet.co.uk/vitablosso... &description=true

Or 

Igennus Vitamin B complex. Nice small tablets. Full dose is 2 tablets per day. Most people are fine with just single tablet 

igennus.com/products/super-...

IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results

endo.confex.com/endo/2016en...

endocrinenews.endocrine.org...

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate methyl folate supplement and continue separate B12

Thank you SlowDragon. I stopped all supplements a week prior to the blood test as you mentioned. Is there a way I could upload the document so that the results are viewable?

I do not know if i have a t3 issue ? or should i stick to the 125mcg or bring that down to 100mcg?

because of my increased calcium in blood i have been asked +to take 800iu Vit D, which i take using the Spray.

I am vegetarian but do not eat fish - eggs and dairy are in - and have recently started Liposomal B complex from vitablossom. is this ok?

I also have started taking one tablet of Super Strength Magnesium Supplements 1620mg - 180 Magnesium Citrate Capsules - (500mg Elemental Vegan Magnesium) at night because I struggle to sleep.

Suggest you stay on 125mcg daily

Retest again just before appointment with endocrinologist

You will need a separate B12 supplement daily as well as daily Vitamin B complex

As vegetarian you may need to continue separate B11 daily….or possibly eventually be able to reduce separate B12 to 2 or 3 days a week

Thyroid levels

Feb results

FT4: 19.2 pmol/l (Range 12 - 22)

Ft4 much better at 72.00% through range

FT3: 4 pmol/l (Range 3.1 - 6.8)

Ft3 currently still low at 24.32% through range

Improving low vitamin levels should help improve conversion

Likely better taking 125mcg every day

Cut Accord 100mcg into 1/4s

Use a sharp craft scalpel or pill cutter

Retest thyroid levels again in 2-3 months

thyroid blood tests early morning, ideally just before 9am and last dose levothyroxine 24 hours before test 

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

List of private testing options and money off codes

thyroiduk.org/getting-a-dia...

If you can get GP to test vitamins then cheapest option for just TSH, FT4 and FT3

£29 (via NHS private service ) and 10% off down to £26.10 if go on thyroid uk for code

thyroiduk.org/getting-a-dia...

monitormyhealth.org.uk/

Monitor My Health also now offer thyroid and vitamin testing, plus cholesterol and HBA1C for £65 

(Doesn’t include thyroid antibodies)

Are you already on gluten free or dairy free diet?

Hashimoto's frequently affects the gut and leads to low stomach acid and then low vitamin levels 

Low vitamin levels affect Thyroid hormone working 

Getting all four vitamins at optimal levels essential

Poor gut function with Hashimoto’s can lead leaky gut (literally holes in gut wall) this can cause food intolerances.

Most common by far is gluten. Dairy is second most common. 

 A trial of strictly gluten free diet is always worth doing

Only 5% of Hashimoto’s patients test positive for coeliac but a further 81% of Hashimoto’s patients who try gluten free diet find noticeable or significant improvement or find it’s essential

Similarly few months later consider trying dairy free too. Approx 50-60% find dairy free beneficial

Hashimoto’s and leaky gut often occur together

Both dairy and gluten are inflammatory foods

A strictly gluten free diet helps or is essential due to gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link) 

Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and may slowly lower TPO antibodies 

While still eating high gluten diet ask GP for coeliac blood test first or buy test online for under £20, just to rule it out first 

Assuming test is negative you can immediately go on strictly gluten free diet 

(If test is positive you will need to remain on high gluten diet until endoscopy, maximum 6 weeks wait officially) 

Trying gluten free diet for 3-6 months. If no noticeable improvement then reintroduce gluten and see if symptoms get worse

Non Coeliac Gluten sensitivity (NCGS) and autoimmune disease

pubmed.ncbi.nlm.nih.gov/296...

The predominance of Hashimoto thyroiditis represents an interesting finding, since it has been indirectly confirmed by an Italian study, showing that autoimmune thyroid disease is a risk factor for the evolution towards NCGS in a group of patients with minimal duodenal inflammation. On these bases, an autoimmune stigma in NCGS is strongly supported

nuclmed.gr/wp/wp-content/up...

In summary, whereas it is not yet clear whether a gluten free diet can prevent autoimmune diseases, it is worth mentioning that HT patients with or without CD benefit from a diet low in gluten as far as the progression and the potential disease complications are concerned

restartmed.com/hashimotos-g...

Despite the fact that 5-10% of patients have Celiac disease, in my experience and in the experience of many other physicians, at least 80% + of patients with Hashimoto's who go gluten-free notice a reduction in their symptoms almost immediately.

Thank you SlowDragon. I will look into obtaining the supplements. Do you know if GP's still give B12 injections?

SlowDragon profile image
SlowDragonAdministrator in reply tonimble

Not unless you have Pernicious Anaemia

As vegetarian your low B12 is almost certainly linked to vegetarian diet

nimble in reply toSlowDragon

Thankyou once SlowDragon. I have ordered the B12 drops.I found the B12 links on deficiency extremely helpful and can see similarities with a number of symptoms.

I will test again in 2 to 3 months. Hopefully, fingers crossed, the picture will look a lot better.

Really appreciate your advice and guidance.

How long have you been vegetarian

All vegetarians should supplement B12 daily

Are you already on gluten free/dairy free diet

only just spotted your dire ferritin result at 31

Never supplement iron without doing full iron panel test for anaemia first and retest 3-4 times a year if self supplementing. It’s possible to have low ferritin but high iron 

Medichecks iron panel test 

medichecks.com/products/iro...

As vegetarian likely to need to supplement iron

It’s extremely difficult to maintain good iron levels on non-heme iron

Heme iron v non heme

hsph.harvard.edu/nutritions...

cks.nice.org.uk/topics/anae...

Serum ferritin level is the biochemical test, which most reliably correlates with relative total body iron stores. In all people, a serum ferritin level of less than 30 micrograms/L confirms the diagnosis of iron deficiency.

Look at increasing iron rich foods in diet 

Eating iron rich foods like liver or liver pate once a week plus other red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption

An article that explains why Low ferritin and low thyroid levels are often linked

Great in-depth article on low ferritin 

oatext.com/iron-deficiency-...

drhedberg.com/ferritin-hypo...

This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.

Thyroid disease is as much about optimising vitamins as thyroid hormones

We have received further information the lab about ferritin reference ranges. They confirm that they are sex dependent up to the age of 60, then beyond the age of 60 the reference range is the same for both sexes: 

Males 16-60: 30-400 ug/L

Female's: 16-60: 30-150

Both >60: 30-650 

The lower limit of 30 ug/L is in accordance with the updated NICE guidance and the upper limits are in accordance with guidance from the Association of Clinical Biochemists. ‘

From birth till 35 years old I was a non-vegetarian following which i became vegetarian (about 20 years ago) I do eat still products containing egg but thats as far as it goes.

Although I fast intermittently during the week (a couple of days usually where no milk or gluten, no sugar or salt either- typically drink water, black coffee and light liquids unsweetened). On my non fast days, which i will vary from week to week so they do not fall on the same days each week, I do take dairy and gluten products.

I will do the iron panel test first as you suggested and post the results.

The GP prescribed ferrous fumerate for two months and I completed that course a few weeks ago.

Suggest you read the many, many posts and replies by humanbean on iron/ferritin

It’s likely to take 9-12 months to improve low iron/ferritin to a GOOD level……..and just as importantly an ongoing maintenance dose to KEEP ferritin at a good level

Many, many Hashimoto’s patients need to work hard continuously to maintain good iron and ferritin levels. That’s likely not possible on vegetarian diet without iron supplements

Levothyroxine can not work properly unless all for vitamins are OPTIMAL……

Fasting on such regular basis likely significantly reducing your conversion rate of Ft4 to Ft3

Low Ft3 results in low vitamin levels

Low vitamin levels results in poor conversion rate of Ft4 to Ft3 ….resulting in low Ft3
