l have taking 10.000ius daily for the last two years - prior to that l was taking 20.000ius - and my levels are 98 - still too low.
150/225 is the optimum level according to my books on vitamind3deficiency. Seems most of us with ms have this problem.
Have you noticed that how adverts for cereals/yoghurts etc are all now fortified with vitd3.
My level 5yrs ago was as low as yours. Except when l asked my consultant neuro about vitd - he said a normal diet would provide enough!! - l hope he is eating his words now as so many GP’s are realising the importance of Vitd3 - and vitb12.
lt is such a cheap supplement to buy - only about £15 per annum.
