Medichecks Blood Results

[Newtohashimotos2025]

Hello,

I had posted last week following a diagnosis of autoimmune hypothyroid. I asked my GP to also test my b12 and folate but he refused.

I organised a blood test through Medichecks and will copy my results below.

Just looking for advice now on where to start with supplementing. Which brands do people recommended, dosages etc.

Vitamin b12 active - 53.6. (Range >37.5-187.5)

Folate 8.3 (Range >7-35)

Vitamin D 54 (Range 50-200)

I will also copy in my thyroid hormone results and autoimmunity below.

TSH 3.73 (range 0.24-4.2)

Free T3 4.8 (range 3.8-6.8)

Free Thyroxine 19 (range 12-22)

Autoimmunity

Thyroglobulin 476 (range 0-115)

THYROID PEROXIDASE ANTIBODIES 394 (range 0-34)

Thanks for reading!

I thought I’d share with you where I like my vitamin 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.

I would look to supplement Vitamin D and improve B Vitamins by taking a good B complex. SlowDragon has great links on supplements.

How long have you been taking 50mcg Levo prior to this blood test? As TSH should always be under 2 & most members here reporting they feel best when this falls nearer/ under 1, it’s highly likely you will need an increased dose.

[Newtohashimotos2025 in reply to Buddy195]

So I have only been taking 50mcg levothyroxine for 2.5 weeks. My TSH was nearly 18 prior to this.

The blood test I had done was really to check my vitamin levels as I didn’t think the Levo would have had much of an effect in that timeframe but it appears that it has done so!

Thanks for sharing!

[Buddy195 Administrator in reply to Newtohashimotos2025]

Personally I would re check TSH, FT3 and FT4 after 6-8 weeks of being on Levo (I actually like to wait 8 weeks as it takes my body this time to fully adjust).

[Newtohashimotos2025 in reply to Buddy195]

So my GP wanted a further blood test 4 weeks after starting Levo. They do not check FT3 though.

On looking at my thyroid hormone result from today - can you interpret them? I am not really that clued up on FT3 and FT4.

[Buddy195 Administrator in reply to Newtohashimotos2025]

This is a link to a ‘pinned’ post with calculators to work out percentages

healthunlocked.com/thyroidu...

Currently your FT4 is at 70% but FT3 is lower at 33.3%. When I was first diagnosed/ began treatment, my percentages fluctuated a lot. Having key thyroid vitamins at an optimal level can also make a significant difference- so do follow advice by SlowDragon to improve these.

It is unusual for GPs to retest after just 4 weeks of starting thyroid treatment, as it can take 6-8 weeks for your body to adjust to the Levo fully.

Do share your next blood test results with us, as with a TSH over 2, it’s likely you will need an increase in Levo. I’m a huge fan of making low and slow changes and I like to adjust Levo in increments of 12.5mcg. However, other members report no adverse effects increasing by 25mcg.

[Newtohashimotos2025 in reply to Buddy195]

I will definitely share my next result with the forum - thank you for sharing the calculator.

I have ordered my vitamin d and will follow Slowdragon advice.

This forum is absolutely brilliant!

Thank you all!

By posting and listening to advice from members, I (like many, many others here) managed to turn my health around.

My top tip to new members is to not make too many changes at once (eg I tried eliminating both gluten and dairy at the same time- then got in a muddle trying to work out what change was beneficial!)

Keep posting and asking questions- we are here to help and support 🦋

[Newtohashimotos2025 in reply to Buddy195]

It really is amazing the amount of advice and support on here!

I have actually stoped eating gluten - pretty much as soon as I got my diagnosis. My NHS test showed my antibodies were over 1900. My latest test from Medichecks it was almost 400 so quite a big difference in a short time frame!

Improve Vitamin D, folate and B12 as outlined in my replies on your previous post

healthunlocked.com/thyroidu...

Only add one vitamin supplement at a time, then wait 10-14 days to assess before adding another

Starting with vitamin D, then B12, folate and magnesium

[Newtohashimotos2025 in reply to SlowDragon]

Thank you so much I have looked back at your reply and will follow this. Do you suggest starting with vitamin D3?

[SlowDragon Administrator in reply to Newtohashimotos2025]

Yes start with vitamin D

Vitamin D mouth spray by Better You is very effective as it avoids poor gut function.

There’s a version made that also contains vitamin K2 Mk7.

One spray = 1000iu

amazon.co.uk/BetterYou-Dlux...

Suggest you start with 2 or 3 sprays per day

(2000iu-3000iu)

Retest in 3-4 months

[Newtohashimotos2025 in reply to SlowDragon]

Excellent thank you I have ordered the spray!

Do you have a b12 dose and brand recommendation?

[SlowDragon Administrator in reply to Newtohashimotos2025]

Yes replied on previous post

[Newtohashimotos2025 in reply to SlowDragon]

See that now thank you!

hi Newtohashimotos2025 , I take the following supplements:

Liquid B12 Methylcobalamin by Metabolics

Methylfolate by Ethical Nutrition (5-MTHF)

Vitamore D, which gets absorbed faster than “regular” vitamin D supplements. To make sure the vitamin D knows where to go to (and to prevent it potentially storing in my tissues / arteries), I take vitamin K2 by Vitamaze and to make sure it doesn’t deplete my magnesium storage, I take liquid, ionic magnesium chloride by Good State.

I hope you’ll find what works best for you and that you can find what brands and doses work best for you, it’s very personal. The B12 I use is in a very high dose so I take it a couple of times a week. I’ve been reading more about the risks of taking too much B12 and apparently that’s not good either.

[Newtohashimotos2025 in reply to PinkCat2023]

Thank you so much for sharing this. It really is a minefield so very grateful for all the advice.
