Hi could anyone please give their thoughts on my recent blood results? I increased from 50mcg levo to alt 50/75 for three weeks in June and have since been on the full 75mcg for 5/6 weeks and my doc wants me to reduce back to 50/75 as I have gone under the tsh range. I will show my previous results from May followed by those from this week and my vit results from Feb 17 and this wekl’s
TSH May 2.67 July 0.18 (0.35-5 mU/L)
Ft4 May 18.2 July 22.9 (11-23 pmol/L)
Vit D 2017 42 July 72 (50-150 nmol/L)(supplemented with 10mcg vit D3 since first result)
B12 2017 408 July 467 (200-900 ng/L ( no supplements)
Ferritin 2017 76 July 79 (12-300 ug/L)
Folate 2017 3.5 July >20
Told I’m not anaemic and liver and kidney functions all good. Thanks

and your doctor is making the same mistake as all of them, dosing by TSH. TSH is not a thyroid hormone, it's a pituitary hormone which tells the thyroid to produce thyroid hormone if to little is detected. Your thyroid hormone - FT4 - is currently 22.9 (11-23 pmol/L) so it's in range. No real need to reduce unless you actually feel overmedicated.
What you really need is FT3 testing, at the same time as TSH and FT4 as advised in your previous post. This will tell you how well you convert T4 to T3. T3 is the active hormone which every cell in our bodies need. If your FT4 and FT3 are in balance near the top of the range, you are converting well and most likely optimally medicated. If your FT4 is high in range and FT3 low in range you are not converting well at all and may benefit from the addition of T3 to a slightly reduced amount of Levo. Most doctors have had an infomation bypass where T3 and FT3 are concerned.
Vit D 2017 42 July 72 (50-150 nmol/L)(supplemented with 10mcg vit D3 since first result)
10mcg D3 is 400iu and I'm amazed that your level has actually risen taking that amount. Most people need a maintenance dose of around 1000iu daily when their level is good.
The Vit D Council, the Vit D Society and Grassroots Health all recommend a level of 100-150nmol/L. With your level I would be supplementing at 3000iu daily until I reached the recommended level then I would find my maintenance dose which may be 2000iu daily, maybe more or less, maybe less in summer than winter, it's trial and error so it's recommended to retest once or twice a year to keep within the recommended range. You can do this with a private fingerprick blood spot test with City Assays vitamindtest.org.uk/
There are important cofactors needed when taking D3 as recommended by the Vit D Council -
D3 aids absorption of calcium from food and K2-MK7 directs the calcium to bones and teeth where it is needed and away from arteries and soft tissues where it can be deposited and cause problems such as hardening of the arteries, kidney stones, etc.
D3 and K2 are fat soluble so should be taken with the fattiest meal of the day, D3 four hours away from thyroid meds.
Magnesium helps D3 to work. We need Magnesium so that the body utilises D3, it's required to convert Vit D into it's active form. So it's important we ensure we take magnesium when supplementing with D3.
Magnesium comes in different forms, check to see which would suit you best and as it's calming it's best taken in the evening, four hours away from thyroid meds
Ferritin should be half way through it's range. You can help raise your level by eating liver regularly, maximum 200g per week due to it's high Vit A content, and including lots of iron rich foods in your diet apjcn.nhri.org.tw/server/in...
Also liver pate and black pudding.
B12 2017 408 July 467 (200-900 ng/L ( no supplements)
This is low. According to an extract from the book, "Could it be B12?" by Sally M. Pacholok:
"We believe that the 'normal' serum B12 threshold needs to be raised from 200 pg/ml to at least 450 pg/ml because deficiencies begin to appear in the cerebrospinal fluid below 550".
"For brain and nervous system health and prevention of disease in older adults, serum B12 levels should be maintained near or above 1000 pg/ml."
You could supplement with sublingual methylcobalamin lozenges 1000mcg daily.
When taking B12 we need a B Complex to balance all the B vitamins. Good makes are Thorne Basic B and Igennus Super B.
Sorry I didnt put in the folate range - it’s 3.9-19.8 and my result was >20
Oh I see. I read that as your result was 3.5 and the range was over 20.
OK, so folate is good, high folate apparently isn't a problem when B12 is high. I will remove my comment in my previous post to avoid confusion.
You still need a B Complex when taking B12 to balance the B vitamins. Out of the two suggested, Igennus Super B x 1 tablet has a smaller amount of methylfolate than the Thorne, so would be a better choice.
