hypothyroidism zinc deficiency connected? foods interfering with medicine?

Hi i am new to this website wish i'd found it a few years ago as it seems a very helpful community on here :-) I have been on levothyroxine since i was 14 for 8 years now i am now on 125mg which i take every morning 20/30mins before food + tea.

Around 2 years ago I changed my diet to dairy free and gluten free and found I began feeling less sluggish and bloating disappearing.

more recently I am noticing my memory is slowing down and I am finding it difficult to concentrate on anything, feeling agitated and irritable, feeling really tired and low, gurgling tummy, constipation, cramps diarrhea and hair loss I was wondering if there are any other foods that disrupt your thyroid levels and if there are other medical issues associated with hypothyroidism? Also I recently had a zinc test due to my symptom of hair loss tests came out very low on Zinc and was told to buy some zinc supplements from a shop, does anyone Know the recommended daily amount of zinc?

many thanks,

  • I don't know about the zinc, but I take 30 MG's at about 8:00 pm. I was told it can help lower cortisol at night, but it takes several hours to work. I also take magnesium and D3 at night, as well as K2. Those are supposed to go together, from what I was told. I found that oats, buckwheat, quinoa, and eggs affect me the same way as gluten. Are you gluten free or just wheat free? Some have problems with dairy, as well.

  • Hi Hannah

    Yes, minerals and vitamins are also very important and this is a list which will be helpful.


  • Forgot to say you should be waiting an hour to eat after taking T4 and no calcium or iron for 4 hours before or after taking it.

  • Two replies which I was going to make. The Thyroid UK site gives so much information. I started my thyroid journey over 25 years ago and my GP suggested minerals and vitamins then as tests came back low. Last year with things not going so well I stopped taking these things with the idea of doing a baseline again. I never actually got around to that but noticed I wasn't too good when I stopped them so with the help of many comments on here I'm back on them again plus some others. I feel so much better! My TSH was unreadable but my FT4 at very top of range and FT3 midway so there was a suggestion I may not be converting well. The lab was suggesting with such a low TSH that I was over medicating and my GP chose to believe that rather than my symptoms! in fact I was told to stop my vitamins etc to raise my TSH. I ignored that! Listen to your body! It knows you better than anything else.

  • Couldn't agree more about listening to your body!

  • As for other foods that can disrupt your thyroid levels, have a look at this.


    Hope this helps, Grey

  • zinc is needed for thyroid function at the hormonal level in the cells.

  • I saw a kiniesiologist and was recommended to take 10 drops in water at night. I use liquid zinc from pure bio :-)
