Supplement for vit D please

Vitamin D 62.3 (50 - 75 vitamin D suboptimal. Advise on safe sun exposure and diet)

in Dec 2017

It was 72 (50 - 75 vitamin D suboptimal. Advise on safe sun exposure and diet )

in June 2017 and I was taking 6000iu D3, so it has dropped a bit.

Symptoms are joint pain, clotty periods, fatigue, muscle and joint weakness, ears ringing, diagnosed vit D deficient Nov 2013, thank you.

What dose D3 are you currently taking?


Your other post shows you are under medicated.

Heavy periods are classic sign of being hypothyroid, also lowering your iron and ferritin as a result

Ears ringing is tinnitus, most likely low B12, also classic sign of hypothyroidism


Vitamin D - suggest you go back to 6000iu if that was keeping level stable. Again you need high dose because you are under medicated

Strictly gluten free diet may help gut heal.

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)."

You can obtain a copy of the articles from Thyroid UK email print it and highlight question 6 to show your doctor
