I think all one can say from those limited results is that your thyroid is struggling a bit. Needs more than average stimulation to produce average results.
Are they not fairly close to mid-range on the average scale?I am assuming if they're within the average scale then they must be ok, but I do get symptoms.
It's not as simple as that. The Frees may be around mid-range, but the TSH should be lower. The fact that the thyroid needs more stimulation from the TSH means that it is struggling a bit. It could sort itself out, but it could get worse. Only time will tell.
Are you on any thyroid meds at all? Nothing in your profile to tell us whether or not you have a diagnosis and on meds. Need to know that to interpret the results.
In that case your results are classed as euthyroid.
A normal healthy person with no thyroid condition would generally have TSH no higher than 2, often around 1, with FT4 around mid-range-ish. This is not set in stone, none of us ar tested for a baseline in health so none of us know what is normal for us.
Here is a graph of TSH level in healthy people, you will see that most have TSH of around 1-2 but some have TSH slightly lower, some have it higher, so yours is coming in around the average:
Your FT4 is at 53% and 51% which again fits in with the above.
It would be helpful to see your current nutrient levels - results, ranges and units of measurement for Vit D and B12 and what you supplement with and the dose:
If male what's the range - 30-400? If so it's low.
If female I expect the range is 13-150 or 20-300 or similar in which case it's OK.
Serum Folate 5.0 ug/L
This is low. As <3ug/L is folate deficiency then you can see how low it is.
No reference range?
Where no range we recommend aiming for double figures.
As you are taking B12 are you also taking a B Complex to keep all the B vitamins balanced?
b12 stores normal, no need to test again for 2 years, if supplementing, which I am.
What is the actual result and unit of measurement? B12 range can be 150-900, 151 is normal, 899 is normal, but there's a great deal of difference, low end can mean deficiency.
Depending on your result you may or may not need a separate B12 supplement, you may only need what's in a B Complex to maintain your level.
I take Vit D3 every day.....
Do you test twice a year which we should when supplementing.
What is your level - result and unit of measurement?
How much D3 do you take? Our level determines how much we need and we usually need more in winter than summer.
Do you take D3's important cofactors - magnesium and Vit K2-MK7?
Serum Ferritin 121 ug/L = Male = range (15 - 300 )
Serum Folate gives range is given as 3.0, just that, no lower or upper limit.
B12 , no range given on results information. Keep in mind it is the NHS blood test. Only says, normal, no need to test again if supplementing, for 2 years.
Ref D3, I take one 250 ug a day in summer but usually double that in winter.
Serum Ferritin 121 ug/L = Male = range (15 - 300 )
OK, so that's a pretty good result.
B12 , no range given on results information. Keep in mind it is the NHS blood test. Only says, normal, no need to test again if supplementing, for 2 years.
My NHS B12 tests have had a result, unit of measurement and reference range. The range has always been 150-900 and the unit of measurement ng/L (which is the same as pg/ml). The problem with saying normal is that if it's below 300ng/L it could suggest B12 deficiency, with anything below 550ng/L it's possible that deficiencies could begin to appear in the cerebrospinal fluid so really there's no such thing as "normal", as I said before normal could be 151 or 899 or anywhere in between.
Ref D3, I take one 250 ug a day in summer but usually double that in winter.
Not been tested for D3.
Do you mean 25ug (which is 1,000iu), surely you're not taking 250ug which is 10,000iu daily in summer, or 20,000iu in winter?
It's essential to test twice a year when supplementing, this tells you if you need to take D3, if you're taking enough or too much. D3 is fat soluble so any excess is stored as it can't be excreted, and if we're taking too much it could lead to toxicity.
You can get an easy home fingerprick blood spot test that an NHS lab in Birmingham offer to the general public for £29 here:
The Vit D Council, Vit D Society and Grassroots Health all recommend a level of 100-150nmol/L, with a recent blog post on Grassroots Health mentioning a study which recommends over 125nmol/L.
I take Magnesium Citrate and Stearate, daily.
Magnesium stearate is a filler/binder/flow agent/excipient in tablets, I have not heard of it being sold as a supplement.
Magnesium helps the body convert D3 into it's usable form.
D3 aids absorption of calcium from food and Vit 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, so it's important to take K2-MK7 when supplementing with D3. 90-100mcg K2-MK7 is enough for up to 10,000iu D3. K2 is a fat soluble vitamin so needs to be taken with some dietary fat unless it's an oil based supplement (eg softgel with oil). As D3 is also fat soluble that also needs to be taken with dietary fat so unless they're both oil based softgels they should be taken at different times of the day to avoid them competing for the fat for absorption.
As already explained, Folate is low and you should be taking a good quality bioavailable B Complex as you're taking B12.
You absolutely must test for Vit D. 10,000iu is a very big dose, it's more than the loading dose for Vit D deficiency and that would only be taken for a few weeks then followed by a smaller maintenance dose.
The Vit D Council, Vit D Society and Grassroots Health all recommend a level of 100-150nmol with a recent blog post on Grassroots Health recommending at least 125nmol. Over 220nmol is likely to lead to toxicity.
Magnesium Oxide is used as a laxative. Magnesium Citrate is also used to help constipation, to use both is rather an overkill, out of the two if you need help in that department then Citrate would be the one recommended.
I know nothing about nitric oxide so can't comment.
Have you tested zinc and copper? These should be in balance. Hypo patients generally are low in one and high in the other so before supplementing we should test to know what, if either, we need.
A.good B Complex is Thorne Basic B, I've used it for many years and many members here use it.
I will reduce the Vit D3, present product, to 1 per week, and see how that goes.
I have ordered the Thorne Research - Basic B Complex - B Vitamins in Their Active Forms - 60 Capsules.
I will also stop taking the Magnesium Oxide and stick with just the Citrate for now.
I made a mistake with the labelling of my Magnesium Oxide capsules, it's complicated and all to do with putting them in a better container than the one they came in, I named them Stearate instead of Oxide.
I shall have to get my mineral and vitamin blood test done, as well as a more in-depth thyroid blood test.
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
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate methyl folate supplement
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.
Now your serum B12 is over 500 (or Active B12 level has reached 70), stop the B12 and just carry on with the B Complex.
Serum TSH Level. Result = 2.13 mU/L average (0.35 - 5.50). --- 34.56% through range
Serum-free T4 Level. Result = 12.3 pmol/L average (7.0 - 17.00). --- 53% through range
May 2022
Serum TSH Level. Result = 1.78 mU/L average (0.35 - 5.50). --- 27.77% through range
Serum-free T4 Level. Result = 12.1 pmol/L average (7.0 - 17.00). --- 51% through range
Your Free T4 results are both mid-range, and your TSH is well within range at a point we would expect from someone with a healthy thyroid.
Ideally you would also have had Free T3 results and also results for TPO Antibodies and Tg Antibodies to be able to say that your thyroid is okay.
If you have symptoms similar to those attributed to hypothyroidism you might want to get some tests done of your minerals and vitamins. There is a lot of overlap in the symptoms of being hypothyroid and having low nutrient levels.
