"There are no issues at school" - are you sure? You have asked her I assume - and she isn't admitting to any but that improvement at the point it is too late to go and relapse next morning sounds very typical. My granddaughter was exceedingly unhappy at school because of issues with teaching attitudes and simply refused to go. Her friends were all at college, she wasn't. Transfer to a local college to do a baseline college course towards her hope of doing theatrical makeup has achieved a dramatic change even though the friends are at other colleges. Could there be social media issues?
If that is not a typo and you really mean 100,000 IU/month, I would go back and discuss the dose the GP is using - 10,000 IU is actually very low for managing vit D deficiency at that level. A more usual recommendation from the experts is 50 to 60,000 IU PER WEEK, taken in one dose or divided in 3 doses. I take a maintenance calcium/vit D supplement that gives me 5,600 IU and my husband is deficient (level of 7) and our GP has given him 25,000 IU per week.
I'm sorry to have to disagree with health's post but less than 10% of vit D requirement can be found in the diet - even for avid pescatarians! Vit D occurs in oily fish and eggs yes, but you would have to eat large amounts every day, milk in Europe is not fortified so getting vit D from milk if you live in the UK doesn't happen. Given her age I imagine your daughter doesn't go out in the sun much between 11am and 3pm between May and September (the only times it is possible to make vit D in skin even in the south of England) - and if she does has make-up or sunscreen on? That pretty much reduces the amount of vit D made in the skin to approaching zero.
I hope this helps a bit. 6
