    Am I on the same page do you mean Charcot- Marie Tooth and blood level measured as ng/ml?
    If so I am not a doctor but in a quick check of the internet, I could find no reason not to take Vitamin D if you have this.
    Many people with diseases are Vitamin D deficient and if we can at least correct that status, many at least, then do not have symptoms/problems caused by low Vitamin D.
    The upper end of the Vitamin D range is 100ng/ml. We also know that the official safe level is 150ng/ml. We also usually encourage a person with a “condition”, to have a level of 80ng/ml.
    So let me ask you this if you do not mind. With a level of 74 ng/ml(?) did it correct any of your symptoms that would be associated with CMT and what were they? (Perhaps you have also not been at this level for very long?) How much Vitamin D do you take to have the 74ng/ml and did you ever take anymore than that to see if it helps you any further?
