Folate

Recent blood tests show that my folate is low again, had a blood test because symptoms started creeping back.

folate 3.3 (4.6-18.7)

TSH 5.4 (0.3-4.2)

FT4 17.7 (12-22)

I'll admit I've been a bit neglectful on my b complex supplements but I got a prescription for folic acid last time I was deficient and took methylated b complex for a good few month afterwards.

I'm currently on another prescription for folic acid and the doctor has increased my thyroxine to 50mcg, was just wondering if its because of my thyroid why I seem to be burning through folate?

Your vitamins will be low because you are incredibly under medicated and hypothyroid

50mcg is only standard starter dose

Bloods should be retested 6-8 weeks later

When hypothyroid we frequently have LOW stomach acid

This should improve as dose levothyroxine is increased slowly upwards in 25mcg steps until on, or near full replacement dose

Frequently necessary to supplement virtually continuously to maintain optimal vitamin levels

Need to regularly retest vitamin D, folate, ferritin and B12

Please add actual results and ranges on other 3

TSH should be under 2

gponline.com/endocrinology-...

Replacement therapy with levothyroxine should be initiated in all patients to achieve a TSH level of 0.5-2.0pmol/L.

How long were you left on just 25mcg levothyroxine?

hey

sorry for the late reply

B12 396 ng/l (197-771)

ferritin 200 ng/ml (30-400)

unfortunately I have no vitamin d test but I've been taking the better for you vitamin d3 spray with k2 if that means anything.

I started 25mcg at around February this year

So bloods should be retested 6-8 weeks after each dose increase

Standard starter dose of levothyroxine is 50mcg

So your GP has been overly cautious

Folate and B12 are low BECAUSE you are under medicated

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

chriskresser.com/folate-vs-...

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 is another option that contain folate, but is large capsule

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

Low B12 symptoms

b12deficiency.info/signs-an...

With such low B12 result taking 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.

Recommend you get vitamin D tested as soon as labs open in Jan

£29 (via NHS private service ) and 10% off down to £26.10 if go on thyroid uk for code

Also vitamin D available as separate test via MMH

Or alternative Vitamin D NHS postal kit

The thyroid hormone status would play a role in the maintenance of vitamin D sufficiency, and its immunomodulatory role would influence the presence of autoimmune thyroid disease. The positive correlation between free T4 and vitamin D concentrations suggests that adequate levothyroxine replacement in HT would be an essential factor in maintaining vitamin D at sufficient levels.

Levothyroxine doesn’t “top up “ failing thyroid, it replaces it. Hence guidelines on dose by weight applies to virtually every single person who takes levothyroxine

Even if we don’t start on full replacement dose, most people need to increase levothyroxine dose slowly upwards in 25mcg steps (retesting 6-8 weeks after each increase) until on, or near full replacement dose

NICE guidelines on full replacement dose

nice.org.uk/guidance/ng145/...

1.3.6

Consider starting levothyroxine at a dosage of 1.6 micrograms per kilogram of body weight per day (rounded to the nearest 25 micrograms) for adults under 65 with primary hypothyroidism and no history of cardiovascular disease.

Traditionally we have tended to start patients on a low dose of levothyroxine and titrate it up over a period of months.

RCT evidence suggests that for the majority of patients this is not necessary and may waste resources.

For patients aged >60y or with ischaemic heart disease, start levothyroxine at 25–50μg daily and titrate up every 3 to 6 weeks as tolerated.

For ALL other patients start at full replacement dose. For most this will equate to 1.6 μg/kg/day (approximately 100μg for a 60kg woman and 125μg for a 75kg man).

If you are starting treatment for subclinical hypothyroidism, this article advises starting at a dose close to the full treatment dose on the basis that it is difficult to assess symptom response unless a therapeutic dose has been trialled.

A small Dutch double-blind cross-over study (ArchIntMed 2010;170:1996) demonstrated that night time rather than morning dosing improved TSH suppression and free T4 measurements, but made no difference to subjective wellbeing. It is reasonable to take levothyroxine at night rather than in the morning, especially for individuals who do not eat late at night.

BMJ also clear on dose required
