Low serum folate = folic acid supplement?

11 Replies

Hello,

My youngest daughter (she's 21) has recently been diagnosed with hypothyroidism.

She's been started on 50 mg Levothyroxine

Her other low result was:

Serum folate 2.2 (2.8-20 ug/L)

For this she's been prescribed folic acid - 5mg daily

I'm a little surprised that it's folic acid especially after browsing the site this morning.

What're your thought please?

That’s all NHS ever prescribes

Once she finishes folic acid prescription she can consider starting a daily vitamin B complex

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.

thyroidpharmacist.com/artic...

Does she have Hashimoto’s?

B vitamins best taken after breakfast

Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule) 

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

endo.confex.com/endo/2016en...

endocrinenews.endocrine.org...

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate methyl folate supplement

What are her vitamin D, B12 and ferritin levels ?

Thyroid will need retesting 6-8 weeks after each dose increase

Which brand of levothyroxine has she started on

Thank you. It was that article or clone of it I was reading. Hashimoto's is a moot point. Her GP requested it and the lab said she'd already been tested and they wouldn't do it again. She has never been tested.

Vit B12 was 319 (180-2000ng/L)

Ferritin and vit D not done

She's on Teva

B12 too low

Suggest she considers add separate B12 approx 2-3 weeks after starting on folic acid

Low B12 symptoms 

b12deficiency.info/signs-an...

methyl-life.com/blogs/defic...

With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a B12 supplement as well as a B Complex (to balance all the B vitamins) initially for first 2-4 months.

once her serum B12 is over 500 (or Active B12 level has reached 70), stop the B12 and just carry on with the B Complex.

B12 range in U.K. is too wide

Interesting that in this research B12 below 400 is considered inadequate

Teva

Is she lactose intolerant?

Many patients do NOT get on well with Teva brand of Levothyroxine.

Teva contains mannitol as a filler, which seems to be possible cause of problems.

Teva is the only brand that makes 75mcg tablet. So if avoiding Teva for 75mcg dose ask for 25mcg to add to 50mcg or just extra 50mcg tablets to cut in half

But for some people (usually if lactose intolerant, Teva is by far the best option)

Most easily available (and often most easily tolerated) are Mercury Pharma or Accord

Mercury Pharma make 25mcg, 50mcg and 100mcg tablets 

Accord only make 50mcg and 100mcg tablets 

Accord is also boxed as Almus via Boots, and Northstar 50mcg and 100mcg via Lloyds ....but Accord  doesn’t make 25mcg tablets

beware 25mcg Northstar is Teva

List of different brands available in U.K.

Posts that mention Teva

Teva poll

Once she finds a brand that suits, best to make sure to only get that one at each prescription.

Watch out for brand change when dose is increased or at repeat prescription.

Government guidelines for GP if you find it difficult/impossible to change brands 

gov.uk/drug-safety-update/l...

If a patient reports persistent symptoms when switching between different levothyroxine tablet formulations, consider consistently prescribing a specific product known to be well tolerated by the patient. 

academic.oup.com/jcem/artic...

Physicians should: 1) alert patients that preparations may be switched at the pharmacy; 2) encourage patients to ask to remain on the same preparation at every pharmacy refill; and 3) make sure patients understand the need to have their TSH retested and the potential for dosing readjusted every time their LT4 preparation is switched (18).

Levothyroxine is an extremely fussy hormone and should always be taken on an empty stomach and then nothing apart from water for at least an hour after

Many people take Levothyroxine soon after waking, but it may be more convenient and perhaps more effective taken at bedtime

verywellhealth.com/best-tim...

No other medication or supplements at same as Levothyroxine, leave at least 2 hour gap.

Some like iron, calcium, magnesium, HRT, omeprazole or vitamin D should be four hours away

(Time gap doesn't apply to Vitamin D mouth spray)

If normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test

If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal

Suggest you get her a weekly pill dispenser so it’s easy to remember to take levothyroxine everyday

And get her a vitamin D test here

vitamindtest.org.uk

Test twice yearly when supplementing 

What’s her diet like

Is she vegetarian or vegan

Gluten free or dairy free

She needs to request ferritin to be done at next thyroid test

Or get tested privately along with BOTH thyroid antibodies

Thank you SlowDragon . Fab points to digest.She's on no particular diet: eats most things

SlowDragonAdministrator in reply to RexandBoone

ok

Come back with new post once she gets retested after 6-8 weeks on 50mcg levothyroxine

Book early morning test around 9am and last dose levothyroxine 24 hours before test

Plus push for testing iron and ferritin

You will need to test thyroid antibodies privately

But virtually guaranteed she has Hashimoto’s as you do

Coeliac blood test necessary once thyroid antibodies confirmed

Personally, I would never take folic acid again, I would only ever take methylfolate.

Some people come on to the forum with very high levels of folate. I wonder if they actually have lots of unmetabolised folic acid in their blood. If they switch to methylfolate their levels sometimes drop dramatically. My personal opinion is that this happens because their folate is actually getting used, whereas folic acid builds up and does nothing much or does what it has to extremely slowly.

Whether someone can metabolise folic acid well is probably mostly due to genetics. MTHFR problems are one cause for having problems. About 50% of the global population has less than ideal versions of the MTHFR genes.

One thing to consider is that vitamin B12 and folate have a strong relationship. For the body to make use of B12 it must have adequate levels of folate. But in cases of deficiency or low levels of either, it is essential to start supplementing B12 about a week before starting to supplement folate, if both are needed.

There are very high dose methylfolate supplements that can be bought on sites selling supplements. If I was deficient I might buy 30 doses of 5000mcg, but then I would reduce to 1000mcg. When my level was where I wanted it to be I would reduce again to 400mcg.

It may be that a good quality B Complex might do the job without any additional methylfolate. But I have to take an extra methylfolate supplement on top of a B Complex . If I don't my level drops into my boots.

Thank you humanbean . It's quite fascinating. How do people decide on which tests and frequency (across this forum)? It's not like it's cheap

humanbean in reply to RexandBoone

I agree that testing is a worrying drain on most people's resources. There are certain tests that people do that crop up time and time again. The most common one are the thyroid tests done by various blood testing companies :

I was going to try and help you with examples but my Firefox browser has just blown up and I can't see the Medichecks website any more, nor can I log in.
