Serum ferritin level is the biochemical test, which most reliably correlates with relative total body iron stores. In all people, a serum ferritin level of less than 30 micrograms/L confirms the diagnosis of iron deficiency.
Never supplement iron without doing full iron panel test for anaemia first and retest 3-4 times a year if self supplementing. It’s possible to have low ferritin but high iron
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
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.
We have received further information the lab about ferritin reference ranges. They confirm that they are sex dependent up to the age of 60, then beyond the age of 60 the reference range is the same for both sexes:
Males 16-60: 30-400 ug/L
Female's: 16-60: 30-150
Both >60: 30-650
The lower limit of 30 ug/L is in accordance with the updated NICE guidance and the upper limits are in accordance with guidance from the Association of Clinical Biochemists. ‘
Thank you. My GP wont treat me for low iron as results "normal". I got some Accord Ferrous Sulphate tablets 200mgs and Spatone iron rich water as well as Vitamin D3000 + K2 Better You Spray. Have no choice but to try and treat myself. I was gluten free for a good while then a month or so ago started eating it again so back on gluten free from last week. My alkaline phosphosate has always been low - do you know anything about this?
With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a separate B12 supplement and add a separate vitamin B Complex after a week
Then once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.
If Vegetarian or vegan likely to need ongoing separate B12 few times a week
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12
Post discussing how biotin can affect test results
Am going to buy some of the Vit B12 and Vit B complex recommended on here. My GP tested B12 - 442 ng/L (197 - 771) and folate 6.8 ug/l (3.0 - 26.8). My private blood test for B12 Active was 52.2 pmol/L (37.5 - 188).

If you live in the UK the iron tablets that doctors prescribe can actually be bought in pharmacies without a prescription with a pharmacist's permission.
You've bought Ferrous Sulphate but they are a poor iron supplement because so few people can tolerate them and they irritate the gut badly. Spatone is a poor iron supplement because it has such a low level of iron in it - well below the recommended daily intake.
I treated my own low iron for seven years - almost two years at a therapeutic dose increasing my ferritin up to mid-range, and then five years at a dose that just maintained my ferritin where it was. During the whole process my serum iron was below range at the start and low in range for most of the rest of the seven years. Things changed after seven years and my ferritin started rising dramatically so I gave up iron altogether. It fluctuated a bit over the next few years but is now better than it has ever been. But I still test it regularly.
For info on iron supplements - there are lots to choose from :
The last link above is old now and misses out some newer options like the supplements mentioned in the first two links that have been successful for some people.
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.
Dairy is second most common.
A trial of strictly gluten free diet is always worth doing
Only 5% of Hashimoto’s patients test positive for coeliac but a further 81% of Hashimoto’s patients who try gluten free diet find noticeable or significant improvement or find it’s essential
A strictly gluten free diet helps or is essential due to gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link)
Changing to a strictly gluten free diet may help reduce symptoms, help gut heal
Trying gluten free diet for 3-6 months. If no noticeable improvement then reintroduce gluten and see if symptoms get worse
The predominance of Hashimoto thyroiditis represents an interesting finding, since it has been indirectly confirmed by an Italian study, showing that autoimmune thyroid disease is a risk factor for the evolution towards NCGS in a group of patients with minimal duodenal inflammation. On these bases, an autoimmune stigma in NCGS is strongly supported
In summary, whereas it is not yet clear whether a gluten free diet can prevent autoimmune diseases, it is worth mentioning that HT patients with or without CD benefit from a diet low in gluten as far as the progression and the potential disease complications are concerned
Despite the fact that 5-10% of patients have Celiac disease, in my experience and in the experience of many other physicians, at least 80% + of patients with Hashimoto's who go gluten-free notice a reduction in their symptoms almost immediately.
Similarly few months later consider trying dairy free too. Approx 50-60% find dairy free beneficial
Is my folate low at 6.8 ug/l (3.0 - 26.8)? My private bloods came with a comment from the doctor to say folate levels normal but didnt give any numbers.
