Taking 4000iu per day should mean you see an increase when you next test at 3 months.
That's a high ferritin level you've got. It can sometimes indicate inflammation in your body. Did you also get CRP tested?
Good luck with the private Endo. They're often more open to prescribing even though a lot of them also work for the NHS. Remember to give them your most recent blood test results or it's a waste of a first appointment.
Morning Sunday Girl, CRP HS is 1.01 so whilst it's not high, my research suggests it could be indicative of an inflammation or immune response.
I'm convinced my thyroid is overactive, the NHS ENT consultant who scanned my thyroid goitre said it might be producing thyroid hormone or it might have an autoimmune component. My antibodies aren't obviously showing an issue but I haven't had TSI tested which might point to Graves although I'm not sure I'm entirely symptomatic of Graves.
I'm leaning towards a toxic goitre causing high levels, this could tie in with the high SHBG which is messing up the benefit of HRT and the vitamin deficiencies or of course the deficiencies could be unhelpful to a borderline thyroid performance!
As an example of the impact of high SHBG, my testosterone is 1.48 nmol which is sightly over range, SHBG is 124 (down from 131 in July), meaning FREE Testosterone is 0.01 nmol!!!
The two GPs I've spoken to about high SHBG say it isn't relevant to anything 🙄.
Luckily my GP has just prescribed six months T and it was the private bloods that show the high T level or I'm guessing they'd be stopping or reducing that based on the high total T. I won't be sending that result in!
(Sorry I'm taking the bus down a SHBG cul de sac!)
