Can anyone shed any light on my recent Thyroid test results please? They are all within "normal" range. Am taking 75mcg of Levo - I hadn't taken any Levo when I had the test done. Normal ranges in brackets. Tia.
I Am feeling exhausted most of the time, have been on the 75mcg for quite a while, but even when on a higher dose, I felt rubbish. Have Fibromyalgia as well, but things can all merge, and don't know why I feel exhausted. All my vitamin levels are "normal" except Vitamin D, (40 - normal range supposed to be 75-150) but am addressing that. Vit B12 364 (normal being 181-910). I don't really like increasing Levo, as the side effects over years aren't good, and I think my Osteoporosis has been caused by Levo - can't prove that though.

Osteoporosis can be due to low FT3 as well as high FT4
Your TSH is too high but so us FT4
Your FT3 is too low. You're a poor converter
What were folate and ferritin results and ranges
Your vitamin D and B12 need improving.
Vitamin D is deficient. Aiming to improve to at least 80nmol and around 100nmol may be better . Vitamin D mouth spray by Better You is good as avoids poor gut function. Suggest you supplement 2000iu for 2-3 months and retest. It's trial and error what dose each person needs.
Once you Improve level, very likely you will need on going maintenance dose to keep it there.
B12 is likely too low. Especially if folate is low as well, they work together
Supplementing a good quality daily vitamin B complex, one with folate in not folic acid may be beneficial
Were you originally diagnosed as having Hashimoto's, with high thyroid antibodies?
Are you on strictly gluten free diet, or tried it?
Only add one supplement at a time and wait at least ten days to assess results before adding another
Always take Levo on empty stomach and then nothing apart from water for at least an hour after. Many take early morning, on waking, but it may be more convenient and possibly more effective taken at bedtime.
Other medication at least 2 hours away, some like HRT, iron, calcium, vitamin D or magnesium at least four hours away from Levothyroxine
Many people find Levothyroxine brands are not interchangeable.
Once you find a brand that suits you, 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.
Many patients do NOT get on well with Teva brand of Levothyroxine. Though it is the only one for lactose intolerant patients
Dr Toft, past president of the British Thyroid Association and leading endocrinologist, states in Pulse Magazine,
"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l.
In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l.
Most patients will feel well in that circumstance. But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.
This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)."

Professor Toft recent article saying, T3 may be necessary for many otherwise we need high FT4 and suppressed TSH in order to have high enough FT3
Thanks SlowDragon - lots to take in there! I have started with taking Vit D, Vit K and Mag Glycinate, and I do take my Thyroxine first thing, and then no food for one hour. My Ferratin was 28ug ( normal range 10-291), and Folate was 5.1 ( should be >5.4), so that came back as "abnormal".
Ferritin is far too low. GP should run full iron panel
Eating iron rich foods plus vitamin C or orange juice. Liver or liver pate once a week should help improve
Folate is below range. GP should prescribe, but they only prescribe cheap folic acid. So you may be better taking your own good quality vitamin B complex instead
If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results
