I was diagnosed with Hashis in 2022. I take levothryroxin 100.
I have been struggling with low Vitamin D:
In Dec 2022: Total 250H Vitamin D 18.5 nmol/L; 25OH Vitamin D <25 nmol/L is consistent with deficiency. I was prescribed a loading dose then told to take a multivitamin.
In March 2023: Total 250H Vitamin D 64.6 nmol/L; 25OH Vitamin D >50nmol/L generally considered adequate.
In Feb 2024: Total 250H Vitamin D 47.8 nmol/L; 25OH Vitamin D 25-50 nmol/L is consistent with insufficiency.
In Sept 2024: Total 250H Vitamin D 44.2 nmol/L; 25OH Vitamin D 25-50 nmol/L is consistent with insufficiency
The GP said they don't prescribe Vit Da and I advised me to take multi-vit. I am taking multi-vit. So advised me to take 4000iu per day. I have bought tablets off amazon Vit D3 4000iu.
Please could anyone advise me what else I can do? I have heard 100 is better for people with low thyroid.
Thanks

We don't rate multi vits as they rarely have enough of what you need and other things you don't.... I'd aim for a loading dose of Vit D for a few weeks to kickstart things 🤗
Igennus B complex popular option. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose and may need separate methyl folate couple times a week
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 can be difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 5-7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg)
Post discussing how biotin can affect test results
Your ferritin level was very high in 2022, this could have been due to inflammation, as this would send levels well above the range, but could mask an iron deficiency.
Have you had your iron levels tested recently to see where your levels are? Might be worth doing an iron panel to clarify. If your iron levels are low this can contribute to you feeling tired and you should consider increasing them, as they work with your thyroid medication to convert T4 to T3.
Disgusting that a GP should say they don't supplement Vit D when there's a clear deficiency. And so many do prescribe.
However, I also prefer to take Better You Vit D with K2 spray (one spray per day not the three recommended on the packet) because it absorbs better and gives you more control. It also contains the K2 which the previous respondent pointed out as important so that the D goes to the right places. NHS prescribed Vit D rarely contains that. I went from deficiency status to upper levels of normal within a couple of months.
I also have folate issues so I either take BioCare Methylfolguard or BioCare's MethylB Complex as they are pre-methylated and have good absorption. They are not cheap but as someone who has struggled with B12 issues for twenty years, I find they do the job nicely and you can dose as suits you whilst you are optimising and testing your levels.
Other than that, very good diet of non-processed food and (in my case) minimal gluten and a probiotic when necessary provides good general cover.
