Thanks for the add.
I hope you can read my very long post!
Although I am well versed in Vit D and companions with regards to my own issues (there are many) I am posting regarding my 14 year old son and after any views/opinions.
In August 2014 he had his blood tested following some fatigue and fluctuating thyroid, and his Vit D was 77 nmol/L. he had been out on his scooter all summer and tans very quickly.
This year after a winter of tiredness he had has May,June,July off school with debilitating fatigue which began (we think) with a virus.
Turns out he was very iron deficient and supplements have corrected this
We saw a pediatric endo on 20th July and he was still very tired, feeling exhausted.
On asking her to test his vitamin D she said 'no need, because last August it was at a good level, he has a suntan so has had enough sun'
we explained to her that he has not seen any sun this year because he has been ill since 9 May and that the dark skin is natural. She still refused.
Anyway, we went on holiday to Greece the next day and literally had to carry him though the airports because he was so weak.
On the 4 day in Greek sunshine he started perking up, by the second week we had our energetic cheeky teenage boy back, and by the time we came home he carried his own suitcase through the airport.
Is it possible that a combination on iron and vit D from the sun could have had this effect, or is it a coincidence??
I just don't know but we have been home 10 days and I have been giving him vitamin D drops (1000) daily and he is still much better and starts physio next week to build on the muscle wastage suffered while he was ill. He rode his bike to The shop today and has started doing school coursework he fell behind on last term.
