Extremely common to have low vitamin levels especially if cause of hypothyroid is Hashimoto's also called autoimmune thyroid disease diagnosed by high thyroid antibodies

For full Thyroid evaluation you need TSH, FT4, TT4, FT3 plus TPO and TG thyroid antibodies. Plus vitamin D, folate, ferritin and B12.

Essential to test thyroid antibodies, FT3 plus vitamins

Private tests are available

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.

All thyroid tests should ideally be done as early as possible in morning and fasting and don't take Levo in the 24 hours prior to test, delay and take straight after. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, GP will be unaware)

If antibodies are high this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).

About 90% of all hypothyroidism in Uk is due to Hashimoto's

I think it isn't just a thyroxine thing, I have been low in nutrients, especially folate, iron and ferritin, zinc and b12 whilst suffering from Hashimoto's disease on many blood tests, even when on natural thyroid hormones. My iron got so bad at one point I couldn't actually use the thyroid hormones I was taking and became bedridden for years. Of course we then found out I was also suffering adrenal insufficiency. In answer to your question, yes deficiencies with thyroxine for me are a thing I have to keep on top of. Dr gives me shots of b12 and I also take many supplements to try and stay better.
