You would normally expect the ALP numbers to be within range or going the other way in an adolescent Mehita. They are often elevated, not below normal, as they increase with growth and puberty.
Since this is not the case you would have to think that active disease and malabsorption are likely playing a part in these decreasing numbers and it is something that the doctor needs to address.
My two have had ileal resections and whilst I am not up on where is at with her bloods and supplements Matt certainly has issues with Magnesium, Zinc, Vitamin D and B12. I will confess that I am not always happy with normal reference ranges when he is sitting at the lower end of them and so aim closer to upper limits and supplement accordingly.
Do you mean 600iu? If so, then yes that is a low dose. I had Matt on 2,000iu and a few months ago increased him to 4,000iu.
