Are you taking any vitamin D at all?

You might find a good vitamin B complex helps too.

But if you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results



As you have Hashimoto's then hidden food intolerances may be causing issues, most common by far is gluten. Changing to a strictly gluten free diet may help reduce symptoms and eventually start to lower antibodies. Very very many of us here find it really helps and can slowly lower antibodies, improving symptoms





Have you had antibodies tested recently. It's a good idea to test 2 or 3 times a year see if they are falling


Hi Snapdragon was taking Vit D through Winter levels slowly increased Do I need a maintenance dose ? How are my levels?

Although my TSH is low my T3 and T4 are also low ? Do I need an increase in meds

My TPO antibodies have reduced from about 160 to 80 (0-34 ) since last year

However my TAG antibodies have very slightly increased to 359.3 ( 0-115 )

I am gluten free

I have had a very very stressful year

Any advice very gratefully received


I am also on exactly same 100mcg T4, plus 20mcg T3.

On the advice of my endo, I take T3 in 3 divided doses (10mcg 6am, 5mcg at noon and 5pm) and Levo at bedtime (can be more effective & equivalent to small increase) More on my profile.


If your not supplementing vitamin D then adding 2000-3000iu daily may help aching bones. Magnesium supplements can help too.

Testing vitamin D twice a year, especially until you work out what you need to keep it stable. Might need more in winter than summer.


Vitamin B complex can definitely help too

Do you supplement selenium, zinc or vitamin C or vitamin A?

Your T4 is pretty low. If you are doing more now physically then perhaps you need a slight increase.

But addressing stress, eg yoga, walking, swimming etc might help first.
