I have recently read an article that it is important to take Vitamin D to boost the immune system.
My wife was diagnosed with E.T. over five years ago and sometime ago was advised that it would not be advisable to take Vitamin D due to having E.T.
In recent times, she has found that she has to avoid being in the sun, no doubt due to her condition.
Has anybody any problems taking Vitamin D due to their MPN?
