Serum 25-Hydroxyvitamin D Levels and Risk of Multiple Sclerosis
We have known for some time now that Vit D and sun exposure was very protective against multiple sclerosis (not quite as effective for treatment, however).
What was surprising about this study, and maybe actually not so surprising given that most chronic diseases start long before onset of symptoms…was that higher levels of serum 25 hydroxyVit D were MOST protective prior to 20 years of age. How much will current recommendations to avoid sun exposure at all costs going to impact future rates of MS? Expect higher rates in the near future, as well as ever increasing rates of certain cancers, diabetes and hypertension (all of which Vit D is very protective for…). Of note is that the protective effect was noted only in whites.
