No results for anti-bodies there.


To know if it's Hashi's, you have to have the antibodies tested, and/or and unltra-sound of the gland.

What you have got, though, is very low ferritin, folate and B12. And they will be causing you symptoms.


Yes lots of symptoms


So, you need to supplement them. :)

Don't count on your doctor to help you with that. Doctors know nothing about nutrition - even less than they know about thyroid! So, you've got to do it yourself.


If you dort mind me asking what nutrition should I do.No idear about it



Serum ferritin level 50ng/ml (10-322) - ferritin should be half way through it's range. You could discuss this result with your GP and see if he will offer an iron supplement. If he won't then you can buy Ferrous Fumarate from Amazon and take one tablet twice a day with 1000mg of Vit C to aid absorption and help prevent constipation. Finish the packet (usually 84 tablets) then re-test. Too much iron is as bad as too little. Take iron 4 hours away from thyroid meds (if you take any) and other meds and supplements as it affects their absorption. Eating liver once a week will also help raise ferritin level.

Serum vitamin B12 level 307ng/L (211-911) - Anything under 500 can cause neurological problems. Recommended level is top of range, 900-1000. You could get some Solgar or Jarrows sublingual methylcobalamin lozenges 5000mcg and take one daily, dissolve under the tongue for absorption directly into the bloodstream, don't chew or swallow as stomach acid destroys it. You could reduce dose to 1000mcg daily after a couple of months and stay on that dose as maintenance.

Serum folate level 2ng/ml (5.4-24) - very low. This should be at least half way through it's range. A B Complex is needed when supplementing with B12. You can supplement with Thorne Basic B or Jarrows B Right, both contain 400mcg methylfolate which will help raise folate level. Eating leafy greens also helps.

B vits should be taken in the morning, no later than lunchtime as they are stimulating.

Don't start all supplements at once. Start with one, give it a week or two and if no adverse reaction then add in the second one and again give it a week or two. If no reaction then add in the next etc. This way if you have a problem you will know what caused it.

Have you had Vit D tested? As everything else is low there's a good chance Vit D will be too.


Could I please ask you what mg of ferrous fumarate tablets I should get please


Here you are Gary




They are 210mg tablets and elemental iron content of each tablet is 65mg

Don't forget to re-test after finishing the pack and take each tablet with 1000mg Vit C to aid absorption and help prevent constipation.

Did you get Vit D tested?


No Doctor did not do vit D test. All vits are coming the same time witch would you recommend i start of with



This is the order I would do it. I would start with the iron supplement and you'll need to start Vit C as well as it aids absorption. Give it a week or two and if no adverse reaction then add in the B12. Give it a week or two and if no adverse reaction then add in the B Complex.

As all your other levels were low, it's very likely that your Vit D is also. As this is just as important as the others I urge you to get it tested privately with a blood spot fingerprick test from City Assays, costs £28 vitamindtest.org.uk/index.html The recommended level is 100-150nmol/L so if yours is less then come back for suggestions for supplementing.

And as Eddie has suggested below, testing antibodies will be very helpful. Ask your GP, he may agree. The NHS only seems to do TPO but you can be negative for TPO and positive for TG and the NHS rarely tests that. You can get them tested privately with Blue Horizon bluehorizonmedicals.co.uk/P...


Thank you for your help


I got B12 from Amazon could please check see if this is ok.

Jarrow Methylcobalamin B12, 5000mcg, 60 Vegetarian Lozenges (5000mcg, 60 Cherry Flavour Vegan Lozenges)


I strongly encourage you to get your Thyroid Peroxidase (TPO) and Thyroglobulin (TG) antibodies tested. If you have thyroid autoimmunity, it is possible that it is being precipitated by gut enteropathy ("leaky gut") and/or gut dysbiosis. Just the fact that you have nutritional deficiencies, makes me suspicious that you are not absorbing well; it is a bit unusual for a male to show up with iron deficiency. Take a look at Tom O'Bryan's youtube video on "The Autoimmune Fix". O'Bryan explains how food sensitivities (esp. gluten, soy, yeast, dairy) can mess up the gut, precipitating autoimmunity. This is a double whammy to your digestion: a damaged gut can't absorb well, and thyroid autoimmunity precipitated by a damaged gut further degrades digestion, because T3 (required for good digestion) level drops.
