Presumably you have Hashimoto’s as thyroid levels are hoping around a lot

Have you ever had thyroid antibodies tested?

NHS only tests and treats for deficiencies

It’s down to us to improve low vitamin levels to optimal

Very common when hypothyroid due to being under medicated to have low stomach acid.

Low stomach acid leads to low vitamin levels

Low vitamins are especially common with Hashimoto’s

B12 and folate are both very low

What supplements are you currently taking?

supplementIng a good quality daily vitamin B complex, one with folate in (not folic acid) may be beneficial.

This can help keep all B vitamins in balance and will help improve B12 levels too

Difference between folate and folic acid


Many Hashimoto’s patients have MTHFR gene variation and can have trouble processing folic acid.


B vitamins best taken after breakfast

Igennus Super B is good quality and cheap vitamin B complex. Contains folate. Full dose is two tablets per day. Many/most people may only need one tablet per day. Certainly only start on one per day (or even half tablet per day for first couple of weeks)

Or Thorne Basic B or jarrow B-right are other options that contain folate, but both are large capsules

If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before any blood tests, as biotin can falsely affect test results



Low B12 symptoms


With low B12 result you may need to also take a B12 supplement as well as a B Complex (to balance all the B vitamins) initially for first 2-4 months, then once your serum B12 is over 500 (or Active B12 level has reached 70), stop the B12 and just carry on with the B Complex.

B12 sublingual lozenges



Low ferritin

Ideally need full iron panel test for anaemia

Never supplement iron without doing full iron panel test for anaemia first

Eating iron rich foods like liver or liver pate once a week plus other red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption

List of iron rich foods


Links about iron and ferritin



This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.

Thyroid disease is as much about optimising vitamins as thyroid hormones

No Vitamin D test ?


None of those results are relevant to the adrenals - that would be a cortisol blood test.
