Been a member for a while & have gained good advice by reading posts from others, but first time posting myself. Hope it make sense.
Have under active thyroid, rheumatoid arthritis, pernicious anaemia &, more recently, bullous pemphigoid.
A year ago I was advised that my vitamin D was low & given a course of D3, at the end of which my reading was :- serum 25-Hydroxy vit D3 63.4nmol/L [>75]. I was then advised that this was now OK & to take 800IU vit D3 daily for maintenance.
However, from advice given to people in this community & the fact that I have now been prescribed Prednisolone, for the bullous pemphigoid, which can deplete vit D, I thought it might be an idea to increase this dose & for the last couple of months or so I have been taking 5000IU vit D3 daily, together with vit K2 Mk7.
To make sure that I wasn't overdosing I asked for a blood test this week & was surprised to find that the reading was now :- serum 25-Hydroxy vit D3 level 54.8nmol/L [>75]. The doctor, not knowing that I was on the 5000IU dose, left me a prescription for 800IU daily. I explained to the receptionist that I had been taking the higher dose & so this prescription would be no good. She promised to have a word with the doctor & said I should ring back today. This I did , only to be told to forget the prescription of 800IU & take 5000Iu weekly! I had to explain, again, that I was already taking 5000IU daily, so how was this going to increase my vit D?
Currently waiting for receptionist to ring back whilst feeling more than a little frustrated!
