I have just been to see my MS nurse and asked for a blood test to see if my body is absorbing the Vit D3 5,000 iu supplements I've been taking for almost 8 months.. seems not..I had an appointment with my GP and was told my results came back and I am deficient in Vit D .. last time 8 months ago I was at the low end but not deficient. The range is 50-150 and I think I was 56 last time so low but not under that number. This time I am "36"... how did that happen..?. I also had my Vit B12 checked as last time it too was low but not a worry and this time I am normal (Being a Vegie for 33 years hasn't seemed to cause a problem then.. :-) ) also my Folic is normal (whatever that means..??) and my Calcium is perfectly in the middle (Had Calcium checked as I have developed a "PICA" which is a craving for substances.. for me it is CHALK but you can't eat that so I just pick the lime scale out of my kettle and that seems to quench my cravings for a bit..). So then it was also my Iron which was checked and that is low which maybe the problem causing my PICA...!! So GP told me I am "Anaemic" (pale and interesting sounds more attractive.. ) My Doctor has given me Iron tablets and Vit D3 3,200 iu supplements.. My Dr hopes that with my Iron sorted then I should be more able to absorb Vit D3 even if it is a lower dose than my supplements that I bought over the internet. So now I'm thinking has this last 8 months plus of feeling super knackered been down to me being Anaemic..? or MS fatigue..? Or both..?. How about you..?
