These are my latest thyroid test results from Blue Horizon. Their advice is that my TSH is too low and if on medication, consider reducing it. However, I think these results don't look too bad. I am taking 3 grains of NatureThroid per day and I must say, I feel pretty good ( at last!! ) I would be so grateful if those of you that are so much more knowledgeable than I am would give their opinion please? I think I need to increase my Vit D supplementation? ;-
Biochemistry;
HbA1c-(IFCC) 34 20 - 42 mmol/mol
hs-CRP 0.67 <5.0 mg/L
Ferritin 149.0 13 - 150 ug/L
Magnesium 0.95 0.66 - 0.99 mmol/L
Hormones;
Insulin 49.8 <173(Fasting) pmol/L
Thyroid Function;
TSH L 0.03 0.27 - 4.20 mIU/L
T4 Total 85.9 66 - 181 nmol/L
Free T4 14.00 12.0 - 22.0 pmol/L
Free T3 6.14 3.1 - 6.8 pmol/L
Reverse T3* 15.0 10 - 24 ng/dL
Reverse T3 ratio 26.65 (Normal >15 Ratio Borderline 12-15 Low <12 )
The trouble is with these doctor comments from the labs, is they are the same as any NHS doctor. If they don't know you're on NDT, or if they do know you're on it but don't understand what NDT does to your results, then they wont know what your levels should be like.
When on NDT then TSH is often very low or suppressed, and it tends to lower FT4 as well. It's the FT3 result that is important. Your FT3 is in range and your TSH and FT4 are not unexpected for someone on NDT. If you feel well, stick to your dose.
HbA1c-(IFCC) 34 20 - 42 mmol/mol - Good
hs-CRP 0.67 <5.0 mg/L - Good
Ferritin 149.0 13 - 150 ug/L - are you supplementing or eating lots of liver, black pudding or liver pate? You don't want this to go any higher.
Magnesium 0.95 0.66 - 0.99 mmol/L - Magnesium is not a very reliable test so as it's within the range it's probably fine.
Insulin 49.8 <173(Fasting) pmol/L - Can't comment on that other than to say it's below the limit which is as it should be.
Reverse T3* 15.0 10 - 24 ng/dL
Reverse T3 ratio 26.65 (Normal >15 Ratio Borderline 12-15 Low <12 )
Nothing to worry about here but not a particularly useful test as it can only tell you if your rT3 is high but not why it's high.
Anti-Thyroidperoxidase abs 21.8 <34 kIU/L
Anti-Thyroglobulin Abs 14 <115 kU/L
The TPO antibodies are within range but have you had them tested before and were they higher or over range?
Vitamin D (25 OH) 69nmol/L
The Vit D Council recommends a level of 125nmol/L and the Vit D Society recommends a level of 100-150nmol/L. Supplementing is advised and the Vit D Council suggests that for your current level, to reach the recommended level, then take 3,700iu D3 daily (nearest available is 4,000iu). As they also suggest taking 5,000iu on days we don't sunbathe, you could consider taking 4000-5000iu daily. Retest in 3 months and when you've reached the recommended level then you'll need a 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
Check out the other cofactors too (some of which can be obtained from food).
Vitamin B12 425pmol/L - 575pg/ml
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."
Serum Folate 26.00 8.83 - 60.8 nmol/L
Folate is recommended to be at least half way through it's range, so that's 35+ with that range. You could nudge yours up by taking a good B Complex containing methylfolate rather than folic acid. You may find that 1 x Igennus Super B will be enough.
