Vitamin D deficiency, but...

. Apparently the brand of Cit D your taking isn't working.

  You can continue to take 2000 IU but convert to another brand

I was level 26 and took supplements and slowly my level increased. It takes quite a while.  25 is just on the edge of deficiency rather than insufficiency. I believe around twenty five per cent of the population in UK are vit D insufficient. My pharmacist's assistant was found to be 26 much to the embarrassment of the pharmacist. 

My level was 17 and was put on 20000 iu twice a week for 9 weeks. I then had another blood test and it was 75. I would increase your level to a higher amount and yes, buy a reputable make.I'd also call the nurse and ask her where she got that info as you were bothered by what she said. I hope that helps.

The approach recommended by UK hospital trusts (Gateshead is an example) is to take something more like 60,000 IU per week, either as a single dose or 3 x 20,000IU, for about 8 weeks and then check the levels again. If they are OK you continue with a suitable maintenance dose (here in northern Italy where I live it is recommended to take 2,000 IU/per week, despite the amount of sun we get!). These high dose version can be prescribed by the doctor - as they have to be ordered specially in the UK I think.

However -   if you are taking 2,000IU per day, you really should have some investigations done because it would appear that you may not be absorbing the vit D and there are a few reasons for that. On the other hand - it may be that you are just using it all and not increasing the baseline level.

Hi my result was 20 and I was prescribed 20000 units of fultium d3 daily for 2 weeks followed by a maintenance dose of 800 daily for 60 days  then be retested.
