Vitamin and thyroid tests help

[Nicholajane]

I’ve going for tests next week for thyroxine and vitamin D levels, I had herd different things on here and other sites about when to take it, I take thyroxine and a multi vitamin and fish oils,

I wanted to know should I stop taking them all before my re tests? I’m not sure thanks

You other post says you have Hashimoto's

Multivitamins are not usually recommended on here, in part because they don't have enough of anything. Also with Hashimoto's we need to probably avoid extra iodine

stopping any supplements with biotin 3-5 days before blood tests.

All thyroid tests should 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

Essential to test vitamin D, folate, ferritin and B12.

Always get actual results and ranges. Post results when you have them, members can advise

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

Low vitamin levels affect Thyroid hormone working

Poor gut function can lead leaky gut (literally holes in gut wall) this can cause food intolerances. Most common by far is gluten

According to Izabella Wentz the Thyroid Pharmacist approx 5% with Hashimoto's are coeliac, but over 80% find gluten free diet helps significantly. Either due to direct gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link)

But don't be surprised that GP or endo never mention gut, gluten or low vitamins. Hashimoto's is very poorly understood

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

Ask GP for coeliac blood test first

Persistent low vitamins with supplements suggests coeliac disease or gluten intolerance
