I have just had some bloods done by my GP, all of which are in the normal range. Some are low in range and I would be grateful for any recommendations, especially from SlowDragon
Thanks.
Serum ferritin level 131 ug/L [30.0 -
250.0
Serum vitamin B12 level 267 ng/L [200.0
- 900.0
Serum folate level 6.4 ug/L [3.0 - 20.5];
Serum folate of less than 3 ug/L is used
as a
guide to indicate folate deficiency.
However,
there is an indeterminate zone with
folate levels
of 3-4.5 ug/L, so low folate should be
interpreted
as suggestive of deficiency and not
diagnostic.
Serum total 25-hydroxy vitamin D level
77 mol/L [50.0 - 200.0];

With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a separate B12 supplement and a week later add a separate vitamin B Complex
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
Igennus B complex popular option too. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose
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
I am not vegetarian or vegan and eat plenty of meat ( also lots of vegetables, cheese and fruit)
Results in June
TSH 0.03 ( 0.27-4.2)
FT4. 12.1 (12-22)
FT3 5.8 (3.1-6.8)
I am under a good endocrinologist and am taking Levi 100mcg plus liothyronine 20 mcg per day.
I usually take methyl folate 1000mcg per day, but deliberately didn’t for a couple of weeks to see what would happen. I also take vitamin D in the winter interestingly my B12 has dropped a lot and was almost 4 times higher in 2018
I am heterogeneous for MTHFR
Thank you so much for the recommendations, I will get on it! Of course, the GP is not interested as they are “ in range”
Thank you also for putting in so much time, it is invaluable
Thank you….. my endocrinologist reduced my Levi by 25 mcg recently!
Sorry, I didn’t answer you. I have very non specific symptoms, sleepiness, joint pains and weight gain sine Levi reduced but non specifically B12 as far as I know.
I did discuss my folate with my dentist as I had mildly bleeding gums and a sore tongue. He did not believe it was related and lectured me about cleaning my teeth.
You could try increasing levothyroxine back to 112.5mcg daily and retest in 6-8 weeks
Might need to tweak further
Then (possibly) consider reducing T3 by 5mcg
Personally…..I only function on Ft4 and Ft3 at least over 60% through range…..but then TSH is 0.01
If I reduce levothyroxine or T3 enough to get TSH up to 0.02 ….stuck on sofa and legs stop working
I find it important to very finely tune both levothyroxine and T3 dose
Levothyroxine
125mcg daily too much = Ft4 right at top of range
112.5mcg daily too little = Ft4 right at bottom of range and TSH 0.02
125mcg 4 days and 112.5mcg 3 days = Ft4 at 18-19 ….about right for me but TSH 0.01
I recently tried reducing T3 from 20mcg to 15mcg …..made no difference to TSH whatsoever…..and felt worse ….so back on 20mcg (currently as 4 x 5mcg….but considering going back to 1 x 10mcg and 2 x 5mcg)
My last test for folate was 4.1 (3.1 - 22) but GP said it was fine. A year later I asked for another folate test while they were doing a blood test for diabetes which I dont have. It was refused as I was in range last year!
I now buy folate as if you dont need it, you just pee it out. It takes 3 to 4 months to raise the levels though.
my GP did it this time because my medichecks results were always low. She is also very nice, but having come back “normal” I very much doubt she will do it again.
I think it is time for an evidence based full yearly check for people with thyroid disease ( and other autimmune diseases) but suppose the workload would be too great.
